Integrations
Overview
Connect Deckle to the tools you already use — send from your auth stack, sync contacts, and automate everything.
Every Deckle integration is one of three shapes. Knowing which shape a connector is tells you exactly how it plugs in — and all three are built on the same public API, webhooks, and SMTP relay, so anything not listed can still be wired up with a few lines of code.
The three shapes#
Route a tool's auth & transactional email through Deckle over SMTP — e.g. Supabase, Clerk, Auth0, WordPress.
Stream external contacts and events into Deckle to drive automations — e.g. Segment, Shopify, Stripe.
Trigger on Deckle events and act on the Deckle API from no-code tools — e.g. Zapier, Make.
How they work#
Send-through connectors reuse Deckle’s SMTP relay: you generate a secret key and paste it as the SMTP password, so the tool’s email flows through your verified domain. Inbound connectors give you a signed endpoint URL; the provider posts to it, and Deckle normalizes each payload into a contact or event — which then enrolls matching contacts into your live automations. Bridge connectors use Deckle’s outbound webhooks as triggers and the REST API as actions.

If a connector isn’t listed yet, you can almost always achieve the same result with Zapier, an SMTP config, or a direct API call. Browse the full catalog under Integrations in the dashboard.Manage integrations#
Connect, disconnect, and rotate credentials from the Integrations page in your dashboard. Each connector has its own setup panel — SMTP settings for send-through, an endpoint + signing secret for inbound, and trigger/action references for bridges.
