Automated onboarding emails that know when to stop
Trigger a welcome sequence from signup, delay each step, and drop people the moment they finish onboarding.
A welcome sequence is only useful if it helps someone reach the first useful moment, and stays quiet once they get there. Most sequences fail the second half.
Start from the event, not the calendar
Fire the first email from a signup event, not from "everyone who was created this week". Calendar batches are easy to build and consistently late. An event-triggered campaign starts the clock for that user the moment they actually signed up.
Give later steps a delay. Day-zero mail can be a short orientation. Day-two mail can cover the one action that predicts retention. Stuffing both into the first send just trains people to skim.
Drop finishers automatically
Put onboarding state in a user attribute. Filter the audience on it. Because the audience is evaluated at send time, anyone who activated during a delay is excluded from the next step. You do not need a separate "unsubscribe from onboarding" flag.
That filter is also how you keep the sequence from becoming a product tour for people who already live in the product.
Do not let them re-enter
A user who logs out and signs up again, or who retriggers the same event from a second device, should not restart the whole series. A cooldown on the trigger is the simple fix: once they have entered, they are ineligible for a defined window.
Pair email with in-app, sparingly
Email is the right channel when they are not in the product. Once they open the app, an in-app banner pointing at the same next step is more useful than a second email. Do not send both at the same moment.
Where Retainza fits
Retainza campaigns can trigger on an event with a delay, filter on attributes so finishers drop out, and apply a cooldown so the same user cannot re-enter. Email goes out over your own SMTP.
