Frequently asked questions

Can I do more than one action?

Absolutely — chain extra nodes after Step 3. A common combo is welcome email + log to a sheet + Slack ping, all from the single Substack trigger.

Will it fire for imported contacts?

Depends on Substack's event. Most fire only on genuine new opt-ins; check the trigger's settings if you bulk-import so you don't email an old list.
