Three AI features live directly inside the broadcast composer, where you actually need them.
Subject lines:
Write your email body first, then click the subject line button. The AI reads your content and returns ten subject lines, each tagged with the angle it takes, such as curiosity, benefit, urgency or social proof. Click any one to drop it straight into the subject field.
Getting ten angles rather than ten variations of the same idea is the point. It is much easier to recognise the right angle than to invent it from a blank page.
Rewriting your copy:
The rewrite button takes your existing body and rewrites it. You can ask for shorter, punchier, more formal, friendlier or more educational. The HTML structure is preserved, so your layout survives the rewrite.
Inbox score:
Before you send, click inbox score. The AI reads your subject and body together and returns a score out of one hundred, plus a list of specific problems it found. It looks at things like spam trigger words, the ratio of images to text, link density and patterns that damage sender reputation.
A score in the eighties or nineties with a couple of minor warnings is normal and fine. A low score with several issues is worth fixing before you commit a big send.
A note on judgement:
These are assistants, not replacements. The AI does not know your audience the way you do. Read what it produces, change what does not sound like you, and never send something you have not read.
