Developers often need a credible project address without deploying a mail server. A hosted mailbox reduces operational work while keeping DNS ownership explicit.
Prefer managed delivery
Operating SMTP safely requires reputation, queues, bounce handling, abuse controls and monitoring—not only a server process.
If tests only need to receive mail, Free Domain Mail turns a domain into a receive-only catch-all inbox and offers an API (GET /api/v1/code, /api/v1/links and /api/v1/messages) for reading verification codes and links. It never sends mail, so transactional sending still needs a separate provider.
Keep environments separate
Use dedicated domains or subdomains for development, staging and production when sender reputation matters.
Never commit API keys or DNS verification tokens to a public repository.
Common mistakes to avoid
- Changing production DNS before recording the current values.
- Assuming a DNS record guarantees inbox placement.
- Testing before the previous TTL has expired.
Frequently asked questions
Does Free Domain Mail provide SMTP credentials?
No. It is receive-only, with no IMAP, SMTP or POP3 access. Read mail in the inbox or through the API with a Bearer key.
Can I send mail through Free Domain Mail?
No. It never sends or forwards mail; use a separate sending provider for transactional or marketing email.
