Free custom-domain email for developers
Reviewed by the Free Domain Mail editorial team · Updated
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.
Free Domain Mail uses managed inbound and outbound providers and conservative limits for person-to-person and transactional testing.
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 this provide SMTP credentials?
No. Sending and receiving happen through the browser mailbox.
Can I send a product campaign?
No. Bulk and list-based sending are outside the service's acceptable use.
