One event in.
A sequence out.
Send BigFat AI Labs an event when something happens in your product. The emails, the waiting and the branching happen here.
What a step can do
Events, not schedules
Workflows start from something a contact did. Send the event from your app with one API call and the flow takes over from there.
Delays that respect the clock
Wait an hour, a day, or until a specific point in the future. Contacts sit in the delay without holding a connection open.
Branching on real data
Split a flow on contact fields, on custom data you have attached, or on whether an earlier email in the same flow was opened.
Webhooks out
A workflow step can call your own systems, so an email sequence can also update a CRM or kick off work elsewhere.
Re-entry, decided by you
Choose whether a contact who triggers the same event twice runs the flow twice or is ignored the second time.
Building one
- Step 01
Pick the trigger
Any event you already track starts a workflow: a signup, a purchase, a plan change. Contacts enter the moment the event fires.
- Step 02
Compose the flow
Drag in emails, delays, conditions and webhooks. Branches split on contact data or on how someone responded to an earlier step.
- Step 03
Turn it on
Every run is visible while it happens, so you can see where a contact is in the flow and what the next step will be.
Three that people build first
Onboarding
Walk a new signup through the product over their first week, and stop sending the rest of the sequence once they have done the thing it was nudging them toward.
user.signed-up → Welcome → Wait 2 days → Getting startedCart recovery
Follow up on an abandoned checkout while it is still live, then follow up again with an incentive if the first message goes unanswered.
cart.abandoned → Wait 1 hour → Reminder → Wait 1 day → DiscountRe-engagement
Catch contacts as they go quiet and branch on whether they opened the last thing you sent, so the dormant and the merely busy get different messages.
contact.inactive → If opened last email → Update / Offer
Frequently asked questions
What can trigger a workflow?
Any event you send BigFat AI Labs from your own code, plus inbound email and contact changes. If your product can make an HTTP request when something happens, it can start a workflow.
Can a workflow branch on what someone did?
Yes. A branch checks a condition, such as whether an email was opened or a contact has a given field, and sends each answer down its own path.
What happens if someone enters a workflow twice?
You choose. A workflow can allow re-entry for things like abandoned carts, or run once per contact for things like onboarding.
Can I stop a sequence part way through?
Yes. A workflow can exit early when the contact does the thing it was nudging them toward, so nobody gets chased for something they already did.
