Every broadcast has a 🏷️ Tagging panel under Send Via.
Tags on open. Anyone who opens gets these tags. Up to five, comma separated.
Tags on click. Anyone who clicks any link in the email gets these.
Per link tags. Press Scan Email For Links and it lists every link in your email with a tag box beside each one. Now a click on your pricing link can tag someone differently from a click on your blog link. That is how you find out what people actually want.
Each tag is applied once per person no matter how many times they open or click, so your data stays clean.
The important part: every tag applied this way can start an automation instantly. Build an automation with the trigger "Gets a tag", name the tag, and your follow up runs itself. Tag on open, pitch the openers. Tag on the pricing link, send the buyers guide. Tag on no engagement, run a win back.
Per link tags still work when your links carry personalised merge codes such as your affiliate link with {{tag.aff}} in it, because matching ignores the part of the link that changes per person.
Tagging a click on one particular link:
A tag set for clicking any link fires for every link in the email, including a survey link or a link in your signature. When an email has more than one link, the Mailer points this out. To tag only the people who clicked your offer, use the per-link tags and attach the tag to that link alone.
