[ 01 / 06 ]How it works
What is event-triggered marketing email?
Marketing email that sends because a user did something, like signing up, starting a trial, or going quiet, rather than because you picked a date and a list.
- Each person gets their own run through the automation, on their own clock.
- Segments read live attributes and engagement when the email sends, not when you exported a list.
- An exit event stops the automation the moment someone converts.
- Results are measured per step and per variant, so you can see which email did the work.

[ 02 / 06 ]Automations
Which marketing emails can I send?
Start from a ready-made automation and adapt it, or describe your own to your agent.
Welcome emails
A welcome email on signup, then a getting-started nudge a few days later.
Trial conversion
A value recap as the trial nears its end, then a last-day offer. Stops when they pay.
Win-back
A reason to come back for users who went quiet, then one offer.
Abandoned cart
Reminders after an hour and a day, then a gentle offer. Stops when they buy.
[ 03 / 06 ]Not a newsletter tool
Can I send a newsletter with Send & Retain?
No. There's no blast button, by design. Here's how that differs from a campaign tool.
What triggers a send
You press send on a list
Something a user did
Who gets it
The whole list at once
One person at a time, in their own run
When it stops
When the campaign ends
When the user converts or leaves
Pricing
Grows with every contact you store
Priced on sends. Contacts are unlimited
Safe for an AI agent
One wrong prompt mails everyone
Automations start paused, and there are no blasts to send

Win-back
