The service that carries it out into the world decides how fast it goes, how much it costs and, most of all, how often it lands in the inbox where your reader will see it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That service is called an SMTP service, or a sending service. There are dozens of them, they all describe themselves in the same words, and their pricing pages are built to be compared with nothing. So people pick one at random, or pick the one a friend uses, and never know if it was right for them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide fixes that. I will explain what a sending service does in plain words, the eight things that make one different from another, and then walk through the eight services most marketers choose between. You get real prices at four list sizes, a table that tells you which one fits your situation, and a clear picture of how the ResultsAiX Mailer works with any of them.<\/p>\n\n\n\n<div class=\"aixg\"><div class=\"box done\"><span class=\"bt\">What you will have by the end of this guide<\/span>\n<ul>\n  <li>A clear understanding of what a sending service does and why your WordPress site needs one<\/li>\n  <li>The eight points that separate one service from another, so you can judge any of them<\/li>\n  <li>A side by side view of <a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a>, Amazon SES, Brevo, Mailgun, Postmark, SendGrid, Resend and Elastic Email<\/li>\n  <li>Real monthly costs at 10,000, 50,000, 100,000 and 250,000 emails, from each provider&#8217;s own pricing page<\/li>\n  <li>The right service for your list today, and a simple path as your list grows<\/li>\n<\/ul><\/div><\/div>\n\n\n\n<div class=\"aixg\"><nav class=\"toc\" id=\"contents\">\n  <b>In This Guide<\/b>\n  <ol>\n    <li><a href=\"#what\">What A Sending Service Does<\/a><\/li>\n    <li><a href=\"#differ\">The 8 Things That Make Services Different<\/a><\/li>\n    <li><a href=\"#eight\">The 8 Main Services, One By One<\/a><\/li>\n    <li><a href=\"#prices\">What They Cost, Side By Side<\/a><\/li>\n    <li><a href=\"#which\">Which One For Which Person<\/a><\/li>\n    <li><a href=\"#mailer\">How The ResultsAiX Mailer Works With Them<\/a><\/li>\n    <li><a href=\"#start\">Why I Start People On SMTP2GO<\/a><\/li>\n    <li><a href=\"#plan\">Your First 14 Days<\/a><\/li>\n    <li><a href=\"#faq\">Questions People Ask<\/a><\/li>\n    <li><a href=\"#next\">What To Read Next<\/a><\/li>\n  <\/ol>\n<\/nav><\/div>\n\n\n\n<div class=\"aixg\"><span class=\"kicker\">Part 1<\/span><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what\">What A Sending Service Does<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">SMTP stands for Simple Mail Transfer Protocol. It is the language mail servers use to pass an email from one to the next. When you press send, your email is handed to a mail server, that server talks to the mail server of your reader&#8217;s inbox provider (Gmail, Outlook, Yahoo, Apple and the rest), and the inbox provider decides where it goes: the inbox, the promotions tab or the spam folder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A sending service is a company whose whole business is running those outgoing mail servers well. You give it your email, it delivers it, and it reports back on what happened: delivered, opened, bounced, marked as spam.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Here is the journey of one email from your WordPress site:<\/p>\n\n\n\n<div class=\"aixg\"><div class=\"flow\">\n  <div><b>You Write<\/b><span>a broadcast or automation in the Mailer<\/span><\/div>\n  <div><b>The Mailer Queues<\/b><span>it at the pace you set<\/span><\/div>\n  <div><b>The Service Sends<\/b><span>from its trusted mail servers<\/span><\/div>\n  <div><b>The Inbox Checks<\/b><span>your domain&#8217;s SPF, DKIM and DMARC<\/span><\/div>\n  <div><b>Your Reader Opens<\/b><span>and the result flows back to you<\/span><\/div>\n<\/div><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Why WordPress Needs One<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Out of the box, WordPress hands email to the web server it runs on. A web server is built to serve pages, not to deliver mail at scale. It has no sending reputation, it usually does not sign your email with your domain, and most hosts cap how many emails it may send in an hour.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A professional sending service gives you four things your web server cannot:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Reputation.<\/strong> Mail servers that inbox providers already know and trust.<\/li>\n\n\n<li><strong>Authentication.<\/strong> Every email signed for your own domain, so Gmail and Outlook can prove it really came from you.<\/li>\n\n\n<li><strong>Speed and volume.<\/strong> Thousands of emails an hour, every hour, without your host stepping in.<\/li>\n\n\n<li><strong>Feedback.<\/strong> Bounces, complaints and unsubscribes reported back automatically, so your list stays clean by itself.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The ResultsAiX Mailer is the brain: your list, your tags, your broadcasts, your automations and your reports, all on your own WordPress. The sending service is the engine that carries each email out. You choose the engine, and you can change it, or run several, whenever you like.<\/p>\n\n\n\n<div class=\"aixg\"><div class=\"box note\"><span class=\"bt\">SMTP or sending service: same thing<\/span><p>You will see these called SMTP services, SMTP relays, email APIs, transactional email services and email delivery platforms. For a WordPress marketer they all mean the same thing: a company that sends your email from its servers, on your domain.<\/p><\/div><\/div>\n\n\n\n<div class=\"aixg\"><span class=\"kicker\">Part 2<\/span><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"differ\">The 8 Things That Make Services Different<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Every sending service delivers email. What separates them is how they do it, what they charge and how easy they are to live with. Once you understand these eight points, you can read any pricing page in two minutes and know whether it suits you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Shared IPs Or A Dedicated IP<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every email leaves from an IP address, and inbox providers keep a reputation score for each one.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Shared IP:<\/strong> you send from a pool of addresses the service shares between many good customers. The service manages the reputation for you, and you benefit from the pool&#8217;s history from your very first email. This is what almost everyone should start on.<\/li>\n\n\n<li><strong>Dedicated IP:<\/strong> an address used only by you. Your reputation is entirely your own. It makes sense once you send steadily, at volume, every week, usually from around 100,000 emails a month. It needs a warm-up period, and most services include one on their bigger plans or sell it as an add-on.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Today your domain&#8217;s own reputation matters even more than the IP. Gmail and Outlook judge the domain in your From address, which is why authenticating your domain (SPF, DKIM and DMARC) is the single most valuable thing you can do, on any service.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. API Or SMTP<\/h3>\n\n\n\n<div class=\"aixg\"><table class=\"tbl\">\n  <tr><th style=\"width:24%\">Method<\/th><th>How It Works<\/th><th style=\"width:32%\">Best For<\/th><\/tr>\n  <tr><td>API<\/td><td>The Mailer sends each email as a secure web request with an API key. Fast, and the service can reply with an ID for every message. The <a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a> connection even sends in batches of 50 per request.<\/td><td>Most people. All ten built-in provider connections in the Mailer use it.<\/td><\/tr>\n  <tr><td>SMTP<\/td><td>The Mailer logs in to the service&#8217;s mail server with a host, port, username and password, and passes each email over that connection.<\/td><td>Any service that gives you SMTP details, including one you already pay for.<\/td><\/tr>\n<\/table><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Those are the two ways to hand an email to a service, and the ResultsAiX Mailer supports both. Its Sending tab has a built-in connection for each major service, plus a <strong>Bring-your-own SMTP<\/strong> connection for anything else.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. How They Charge<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">There are three pricing models, and knowing which one a service uses tells you how the bill will grow.<\/p>\n\n\n\n<div class=\"aixg\"><table class=\"tbl\">\n  <tr><th style=\"width:26%\">Model<\/th><th>How It Works<\/th><th style=\"width:30%\">Examples<\/th><\/tr>\n  <tr><td>Pay per email<\/td><td>No plan. You pay a small amount for every thousand emails, and nothing in a month you send nothing.<\/td><td>Amazon SES<\/td><\/tr>\n  <tr><td>Monthly plan by volume<\/td><td>A monthly fee for an allowance of emails, with extra emails charged at a set rate per thousand if you go over.<\/td><td><a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a>, Mailgun, Postmark, SendGrid, Resend, Elastic Email<\/td><\/tr>\n  <tr><td>Marketing platform plan<\/td><td>A plan that also includes the provider&#8217;s own campaign tools. You pay for features you may not use, because the Mailer already does that job.<\/td><td>Brevo<\/td><\/tr>\n<\/table><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Because the ResultsAiX Mailer holds your list, you never pay a sending service by the number of contacts. You only pay for the emails you send. A list of 50,000 people that you email once a week costs about the same as sending 200,000 emails a month.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Daily And Hourly Limits<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most services count your allowance per month. A few count it per day, especially on free plans, and new accounts often start with a lower daily limit that rises once the service has seen you send well. The Mailer handles every kind of limit for you: you type the number into the connection&#8217;s <strong>Daily limit<\/strong> box, and the queue paces itself to fit, then carries on the next day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Deliverability Tools<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every good service signs your email with DKIM once you verify your domain, processes bounces, and reports spam complaints. The differences are in the extras: inbox placement tests, email validation, reputation monitoring, dedicated IP warm-up and log history. Nice to have, but your own list quality and domain authentication do far more for your inbox rate than any extra.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Ease Of Setup<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every service asks for the same core steps: create an account, verify your domain with a few DNS records, create a key, paste it into the Mailer. The difference is how much is in the way. Some services are ready in fifteen minutes. Amazon SES needs a region choice, a domain identity and a request for production access, which takes a day.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Support<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">When you want help, you want a human who knows email. Support ranges from ticket only, through live chat, to phone support and a named account manager on large plans. If you are not technical, good support is worth more than a few dollars a month.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Where Your Data Lives<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Some services let you choose US or EU servers, which matters if your business or your readers are in Europe. Mailgun offers US and EU regions, and the Mailer has a Region box for it. Amazon SES runs in many regions, and you pick one. <a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a> has location-specific servers for the US, the EU and Australia.<\/p>\n\n\n\n<div class=\"aixg\"><div class=\"box tip\"><span class=\"bt\">The one thing that matters most<\/span><p>The service you choose matters less than how you use it. People who reach the inbox authenticate their domain, mail people who asked to hear from them, and grow their volume steadily. Do those three things and every service in this guide will serve you well. Guide 4 covers all three in depth.<\/p><\/div><\/div>\n\n\n\n<div class=\"aixg\"><div class=\"cta\"><span class=\"ct\">One Mailer, Any Sending Service<\/span><p>The ResultsAiX Mailer has built-in connections for every service in this guide, so you pick the engine and your list stays on your own site.<\/p><a class=\"ctab\" href=\"https:\/\/kevinfahey.org\/guide2-mailer\/blog\">See ResultsAiX Mailer &rarr;<\/a><\/div><\/div>\n\n\n\n<div class=\"aixg\"><span class=\"kicker\">Part 3<\/span><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"eight\">The 8 Main Services, One By One<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Here are the eight services marketers most often choose between. Every one of them has a built-in connection in the ResultsAiX Mailer, so whichever you pick, you paste in your key and send. For each one you will see what it is best at, who it suits and exactly what the Mailer asks for.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">SMTP2GO<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a> is a sending service and nothing else, and it does that job very well. Setup is quick, the dashboard is clear, reports are easy to read, and paid plans include chat and phone support as well as tickets. It works both as an API and as an SMTP relay, verifies your domain with three simple CNAME records, and includes a dedicated IP from its Professional plan.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> anyone who wants a reliable service that is easy to live with, from a first list to a list of hundreds of thousands. It is what I use.<\/li>\n\n\n<li><strong>Free start:<\/strong> 1,000 emails a month (up to 200 a day).<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> an API Key.<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Amazon SES<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Amazon Simple Email Service is the lowest cost way to send real volume: you pay per email with no monthly plan. It is built for developers, so the setup uses words like identity, region and sandbox, and new accounts send only to verified addresses until you request production access. The Mailer&#8217;s built-in guide and the Training tab walk you through every step, in order.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> bigger lists that send often, where the saving adds up quickly.

Its free plan allows 300 emails a day, and its paid plans count a monthly volume of emails.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> small lists that want to start free, and businesses that already use Brevo for other channels.<\/li>\n\n\n<li><strong>Free start:<\/strong> 300 emails a day.<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> an API Key.<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Mailgun<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mailgun is a developer favourite with detailed logs that show exactly what each receiving server said.

It keeps broadcast email in its own Broadcast message stream, separate from receipts and password resets, and it expects a clean, opted-in list. It is one of the most respected names in email delivery.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> businesses where every email arriving matters more than the cost per email.<\/li>\n\n\n<li><strong>Free start:<\/strong> 100 emails a month to test with.<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> the Server Token of your Broadcast stream.<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">SendGrid<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SendGrid, now part of Twilio, is one of the best known sending services in the world, with plans that scale into the millions and a dedicated IP included on its Pro plan.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> growing businesses that want a big, established name.<\/li>\n\n\n<li><strong>Free start:<\/strong> a 60-day trial at 100 emails a day.<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> an API Key with Mail Send permission.<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Resend<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Resend is the newest service in this guide and one of the simplest to set up: add your domain, add a few DNS records, create a key. Its free plan includes 3,000 emails a month, and its paid plans have no daily limit.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> people who want to be sending within minutes, on a modern, clean dashboard.<\/li>\n\n\n<li><strong>Free start:<\/strong> 3,000 emails a month (up to 100 a day).<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> an API Key.<\/li>\n\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Elastic Email<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Elastic Email is one of the lowest cost monthly plans for larger volumes, with email verification included on its Starter plan and webhooks, sub accounts and custom rDNS on Pro. With your domain fully authenticated, it is a sound budget choice.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Best for:<\/strong> large lists on a careful budget who want a monthly plan rather than pay per email.<\/li>\n\n\n<li><strong>Free start:<\/strong> 3,000 emails a month (up to 100 a day).<\/li>\n\n\n<li><strong>The Mailer asks for:<\/strong> an API Key.<\/li>\n\n<\/ul>\n\n\n\n<div class=\"aixg\"><div class=\"box note\"><span class=\"bt\">Four more connections in the Mailer<\/span><p>The Sending tab also has built-in connections for SparkPost and Mailjet, a <strong>Bring-your-own SMTP<\/strong> connection for any service that gives you SMTP details, and WordPress wp_mail for quick tests while you set up.<\/p><\/div><\/div>\n\n\n\n<div class=\"aixg\"><span class=\"kicker\">Part 4<\/span><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"prices\">What They Cost, Side By Side<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Every price below is as published by each provider on its own pricing page, in US dollars, with monthly billing.

The Mailer is not tied to any sending service. You connect the ones you choose, decide how they share the work, and change your mind at any time without touching your list, your automations or your reports.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Sending Tab: All Your Connections In One Place<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the Mailer, open <strong>Delivery<\/strong>, then <strong>Sending<\/strong>. The Sending Providers table lists every connection with its provider, whether it is active, its priority, how many emails it has sent today, its daily limit and its last test result. You can add as many connections as you like: any provider, and several accounts of the same provider.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/smtp-service-guide-03-mailer-sending-providers.webp\"><img decoding=\"async\" src=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/smtp-service-guide-03-mailer-sending-providers.jpg\" alt=\"Mailer Sending Providers table with SMTP2GO, Amazon SES and Mailgun connections, priorities, daily limits and OK tests.\"\/><\/picture><figcaption class=\"wp-element-caption\">Every sending connection on one screen.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Adding A Connection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Click <strong>+ Add Sender<\/strong>, give it a Display name and choose the Provider.

It sends a test email through that one connection to your site&#8217;s admin address and shows the result straight away, then records it in the Last test column with the time. You can also send yourself a test from any broadcast before it goes out.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Priority And Automatic Failover<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Give each connection a priority number. The lowest number sends first. If that connection reaches its daily limit or has a problem, the next one in line takes over automatically, so your broadcast keeps going. If a single send does not go through, the queue tries it again with a growing delay, up to three attempts.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Rotation: Share The Work Between Services<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Below the providers table sits the <strong>Send Rotation &amp; Warmup<\/strong> panel. Choose how your connections share the sending:<\/p>\n\n\n\n<div class=\"aixg\"><table class=\"tbl\">\n  <tr><th style=\"width:26%\">Mode<\/th><th>What It Does<\/th><\/tr>\n  <tr><td>Priority + failover<\/td><td>The default. The lowest priority number sends everything, and the next takes over when needed.<\/td><\/tr>\n  <tr><td>Rotate evenly<\/td><td>Spreads sends across every connection. 1,000 emails over 5 connections is about 200 each, and the connection that has sent the least today always goes next.<\/td><\/tr>\n  <tr><td>Weighted shares<\/td><td>You set each connection&#8217;s share, for example 50\/35\/15. A weight of 0 keeps a connection as a backup only.<\/td><\/tr>\n<\/table><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Failover always stays underneath: whichever mode picks the connection, if one has trouble the next in line delivers the email. The panel shows each connection&#8217;s sends today, its share, its capacity left and an Authentication badge that confirms your domain is set up for that provider. Tick <strong>Strict DKIM guard<\/strong> and only authenticated connections take part in rotation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/complete-smtp-service-guide-ys-05-mailer-rotation-warmup.webp\"><img decoding=\"async\" src=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/complete-smtp-service-guide-ys-05-mailer-rotation-warmup.jpg\" alt=\"Send Rotation and Warmup panel sharing sends across three connections, all authenticated for yoursite.com.\"\/><\/picture><figcaption class=\"wp-element-caption\">Share sends between services with weighted shares.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Warmup For A New Account<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A brand new account or a new sending domain has no history yet, so the smart move is to start small and grow. Tick <strong>Warm up<\/strong> on a connection and choose a pace:<\/p>\n\n\n\n<div class=\"aixg\"><table class=\"tbl\">\n  <tr><th style=\"width:26%\">Pace<\/th><th>First Day<\/th><th>Growth<\/th><\/tr>\n  <tr><td>Conservative<\/td><td>50 emails<\/td><td>1.5 times each day<\/td><\/tr>\n  <tr><td>Standard<\/td><td>100 emails<\/td><td>Doubles each day<\/td><\/tr>\n  <tr><td>Fast<\/td><td>500 emails<\/td><td>Doubles each day<\/td><\/tr>\n  <tr><td>Custom<\/td><td>Your number<\/td><td>Your growth factor<\/td><\/tr>\n<\/table><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Then send normally. Each day the queue sends up to that day&#8217;s cap and the rest waits and continues the next day, so a 20,000-email broadcast on the Standard pace completes in about eight days. When warmup reaches the connection&#8217;s daily limit, the row shows Warmup complete.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Daily Limit And The Hourly Ceiling<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Two settings keep your sending smooth and steady:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n\n<li><strong>Daily limit<\/strong>, on each connection. Set it to your plan&#8217;s allowance and the Mailer paces each send to fit, then picks up the next day.<\/li>\n\n\n<li><strong>The hourly ceiling<\/strong>, in <strong>Setup<\/strong>, then <strong>Settings<\/strong>, under Operations: &#8220;Never send more than this many broadcast emails an hour&#8221;. One ceiling for all your broadcasts together, spread evenly across the hour. For example 900 means about 15 a minute and never more than 900 in any hour. Automation and welcome emails are never held back by it, so new subscribers always get their welcome straight away.<\/li>\n\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Next to it, <strong>Queue batch size<\/strong> and <strong>Queue interval (seconds)<\/strong> set your normal sending speed, and an optional sending window lets broadcasts go out only between the hours you choose. On my own list I send at about 2,000 an hour: fast enough to reach everyone the same day, and steady enough that every inbox provider sees a calm, regular sender.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/smtp-service-guide-06-mailer-hourly-ceiling.webp\"><img decoding=\"async\" src=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/11\/smtp-service-guide-06-mailer-hourly-ceiling.jpg\" alt=\"Mailer Operations settings with queue batch size, queue interval and an hourly ceiling of 1,000 emails.\"\/><\/picture><figcaption class=\"wp-element-caption\">One steady hourly ceiling for every broadcast.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Every broadcast can also have its own speed in emails an hour, and its report shows the progress live: how many have gone, how many are waiting, the pace and when it will finish.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/10\/autoresponder-sending-at-scale-mailer-14-broadcast-sending-live-rs.webp\"><img decoding=\"async\" src=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/10\/autoresponder-sending-at-scale-mailer-14-broadcast-sending-live-rs.jpg\" alt=\"Broadcast report showing a live drip send at about 1,500 emails an hour with opens, clicks and revenue.\"\/><\/picture><figcaption class=\"wp-element-caption\">Each broadcast shows its pace live.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Bounces And Complaints Come Back Automatically<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For every API connection, the Sending tab shows a <strong>Bounce &amp; complaint webhook<\/strong> URL with a Copy URL button. Paste it into your sending service&#8217;s webhook settings, tick the bounce, spam complaint and unsubscribe events, and those people are taken off future sends automatically. The Mailer treats a hard bounce (an address that does not exist) differently from a soft bounce (a full mailbox), so real people stay on your list.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><picture><source type=\"image\/webp\" srcset=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/10\/smtp-rotation-email-warmup-mailer-21-reports-list-health-rs.webp\"><img decoding=\"async\" src=\"https:\/\/resultsaix.com\/blog\/wp-content\/uploads\/2026\/10\/smtp-rotation-email-warmup-mailer-21-reports-list-health-rs.jpg\" alt=\"Mailer List Health report with unsubscribes, bounces from the webhook and zero spam complaints.\"\/><\/picture><figcaption class=\"wp-element-caption\">Bounces and unsubscribes come back automatically.<\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Send A Broadcast Through One Connection<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Each broadcast has a <strong>Send via<\/strong> choice. Use it to send one particular broadcast through one connection, for example your partner mailings through a separate account. If that connection reaches its limit mid-send, the others still take over, so the broadcast always completes.<\/p>\n\n\n\n<div class=\"aixg\"><div class=\"box done\"><span class=\"bt\">What this means for you<\/span><p>You can start on one service today, add a second next month, share the work between them, warm up a new one gently and set one steady pace for everything, all from one screen, without ever moving your list.<\/p><\/div><\/div>\n\n\n\n<div class=\"aixg\"><div class=\"more\"><a href=\"https:\/\/kevinfahey.org\/guide2-mailer\/blog\">See ResultsAiX Mailer &rarr;<\/a><\/div><\/div>\n\n\n\n<div class=\"aixg\"><span class=\"kicker\">Part 7<\/span><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"start\">Why I Start People On SMTP2GO<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When someone asks me which sending service to use, my answer is <a href=\"https:\/\/kevinfahey.org\/smtp2go\/blog-complete-smtp-service-guide\" target=\"_blank\" rel=\"noopener\">SMTP2GO<\/a>, and it is the one I use myself.
