About Zapier
Zapier lets you automate tasks between Reply and other platforms. This is useful when there's no direct integration available.
You can connect Reply with thousands of apps and build automated workflows called Zaps. Each Zap consists of a trigger (an event that starts the workflow) and an action (what happens next).
Supported triggers and actions
Triggers – events in Reply that start a Zap:
New Emails Sent – triggers when an email is sent (first step or a follow-up).
New Email Opened – triggers when a prospect opens your email.
New Email Replied – triggers when a prospect replies to your email.
New Person Opt Out – triggers when a prospect clicks the opt-out link.
New Person Bounce – triggers when an email address bounces.
New Link Clicked – triggers when a prospect clicks a link in your email.
Inbox Category Set – triggers when a reply is marked with a specific inbox category (e.g. Interested, Not Interested, Out of Office).
Prospect Finished – triggers when a prospect completes all steps in a sequence.
Add or Update Contact – triggers when a contact is created or updated manually in Reply.
Zapier Step Launched – triggers when a Zapier step is reached in a sequence. Use this to connect with external apps mid-sequence. See the Zapier Step article for setup instructions.
Actions – what Zapier can do in Reply:
Create/Update Person – creates a new contact or updates an existing one in Reply.
Create/Update Person and Push to Sequence – creates or updates a contact and adds them to a sequence.
Mark as Replied – marks a prospect as replied in a sequence.
Mark as Finished – marks a prospect as finished.

💡 You can also map custom variables to default fields when creating or updating contacts and pushing them to sequences.
