What are email campaign webhooks?
Webhooks are HTTP callbacks that notify your systems when campaign events occur, enabling automation without polling MailFleet manually.
Event types
Subscribe to events that matter for your stack:
- campaign.created
- campaign.started
- campaign.paused
- campaign.completed
- email.queued
- email.sent
- email.failed
- email.bounced
- provider.error
- spamassassin.checked
Sample payload
Example JSON (illustrative): {"event":"email.sent","campaign_id":"cmp_123","recipient":"[email protected]","timestamp":"2026-06-15T12:00:00Z"}
Security
Use HTTPS endpoints, validate signing secrets, handle retries idempotently, and verify timestamps on your receiver.
Best for
- Teams syncing campaigns with CRMs
- Ops building custom alerting
- Agencies piping events to client dashboards
Not best for
- Users who only need manual CSV exports without real-time automation
Common mistakes
- Using HTTP instead of HTTPS endpoints.
- Not handling duplicate deliveries on retry.
- Storing signing secrets in client-side code.
Key takeaways
- campaign.created
- campaign.started
- campaign.paused
- campaign.completed
- email.queued
Summary
MailFleet webhooks post HTTPS events — such as sends, bounces, failures, and provider errors — to your endpoints so CRMs, dashboards, and automation stacks stay in sync with desktop campaign activity.
Delivery note: MailFleet helps users manage campaigns through their own sending providers. Delivery outcomes depend on sender reputation, DNS authentication, content quality, recipient engagement, list quality, provider rules, and mailbox filtering systems.
For regulatory context on commercial email in the United States, see the FTC CAN-SPAM compliance guide.
