About the Inbox integration

Add the Inbox piece to a flow, connect your account once, and the rest of the builder can read from it and write to it. Because the piece is open source you can run it on our cloud or self-host it, and combine Inbox with 760+ other apps in the same flow.

Triggers

Start a flow the moment something happens in Inbox

Each trigger below can start a flow on its own, either instantly or on a schedule.

  • New Contact

    Triggers when a new contact is added to your INBOX account (through a form, manual entry, import, or API).

  • New Campaign

    Triggers when a new campaign is created in your INBOX account.

  • Email Bounced

    Triggers when a transactional email permanently bounces (hard bounce) — the recipient address does not exist or is blocked.

  • Email Spam Reported

    Triggers when a recipient marks a transactional email as spam in their inbox.

  • Email Opened

    Triggers each time a transactional email is opened by the recipient. Fires on every open (not unique).

  • Email Link Clicked

    Triggers when a recipient clicks a tracked link inside a transactional email.

Use Inbox in a flow

Connect Inbox once and every trigger and action above is yours to drop into the builder, alongside 760+ other apps. Free to start, on our cloud or your own servers.

Inbox, answered.

Add the Inbox piece to a flow, then authenticate with Basic auth. Once connected, its 6 triggers and 7 actions are available anywhere in the builder.

"New Contact" can start a flow that runs "Add Contact to List", and you can chain Inbox together with any of 760+ other apps and AI steps in between.
