When you need one

The seven defaults cover sequence hygiene. Custom triggers add your team's workflow: routing, tagging, alerts. Examples:
- Tag prospects who clicked a pricing link twice — "warming" for prioritized follow-up.
- Alert the account owner when a large-account prospect replies.
- Tag prospects whose auto-reply mentioned a successor so you remember to chase the new contact.
Building one
- Open Triggers.
- Choose to create a new trigger.
- Set the condition — the prospect behavior to watch.
- Add actions: pause campaign, change status, apply tag, notify.
- Save, then watch it fire on real events before relying on it.
Design rules
- Never weaken the safety defaults — don't build anything that re-contacts opted-out or bounced prospects.
- Prefer tags over status changes — tags are reversible and don't fight the sequence state machine.
- One behavior per trigger — compound triggers are hard to debug.
- Test with one campaign — enable the trigger, run one small campaign, verify the actions fire as expected before going wide.
