Email testing API automation guide
API-based email testing lets automation wait for messages, inspect content, extract links, and fail clearly when a workflow breaks.
Best for: Automation engineers building CI checks for email-dependent flows.
What to automate
Automated email tests should focus on deterministic flows where the expected message, recipient, and link behavior are known.
- Wait for a signup or notification email.
- Extract the first matching verification link.
- Assert subject, sender, and required text.
- Fetch attachment metadata when the workflow sends files.
Keep tests stable
Use unique inbox addresses per run, reasonable timeouts, and test-only data. Do not rely on a public inbox for secrets or production account recovery.
Token access
Zumasia API tokens are approved before use, which keeps automation intentional and rate-limited.
FAQ
Can the API wait for a message?
Yes. The API includes inbox waiting endpoints designed for automation workflows.
Can tests extract links?
Yes. The API can expose message links so tests can continue a verification flow.
Is API access public by default?
No. You request access and claim a token after approval.
