Instant triggers and actions across 7,000+ apps.
Set it up
- Create a secret API key in your Email Fast dashboard (Settings, API keys).
- In Zapier, add the Email Fast app and paste the key when prompted; the connection self-tests against auth-test.
- Pick a trigger (an instant REST hook over the event bus) or an action (a direct API call) and map your fields.
Triggers
Triggers are instant REST hooks over the event-egress bus — a subscription (POST /v1/egress/hooks) that fires the moment a delivery signal lands, not a poll. This is the piece the API-only providers leave out.
| Trigger | Event | Fires when |
|---|---|---|
| Email Sent | email.sent | The MTA accepted the message for delivery (not recipient-confirmed). |
| Email Opened | email.opened | A human open (privacy-proxy prefetches are filtered out). |
| Link Clicked | email.clicked | A tracked link in the message was clicked. |
| Email Bounced | email.bounced | The receiving server rejected the message (hard bounce). |
| Spam Complaint | email.complained | The recipient marked the message as spam (FBL). |
| Send Failed | email.failed | The message could not be sent after exhausting retries. |
| Unsubscribed | email.unsubscribed | The recipient unsubscribed (one-click or preference centre). |
Actions
Every action is a direct call to the REST API, authenticated with your Bearer key.
| Action | Endpoint | What it does |
|---|---|---|
| Send Email | POST /v1/emails | Send a one-off email with an inline subject and HTML body. |
| Send Email (by template) | POST /v1/emails | Send using a stored template slug; subject, body, cc/bcc and reply-to default from the template. |
| Create or Update Contact | POST /v1/contacts | Create a contact or merge attributes into an existing one (used for list/segment membership via attributes). |
| Track Contact Event | POST /v1/events | Record a behavior event on a contact — the segment-membership / CDP signal journeys enroll and branch on. |
| Add Suppression | POST /v1/suppressions | Suppress an address (globally or on one stream) so it is never delivered to. |
| Remove Suppression | DELETE /v1/suppressions | Lift a suppression for an address (a whole stream, or every stream when omitted). |
