What Mail.gw is

Mail.gw is a free disposable email service for temporary addresses, available through the web and an API. It generates an address automatically without registration and says incoming messages arrive instantly. Mailboxes keep incoming messages for 10 minutes, and that period cannot be extended. The service does not support sending email. Mail.gw describes its service as anonymous; its privacy policy says it does not store IP addresses and permanently deletes temporarily stored emails and data. The service suggests temporary addresses for online account signups or sharing private thoughts. Its API creates temporary accounts for tasks such as automating email confirmation during testing. API access is free, requires no key, and has a general quota of 8 queries per second per IP address. Documentation lists a Dart client and compatibility with Mail.tm API libraries when used with Mail.gw's base URL. Notifications use Mercure server-sent events rather than webhooks. Support contact options include email, Discord, and Telegram. Mail.gw says it does not renew its domains and recommends Mail.tm for anyone needing a constant account. The Free plan is listed as free.

Good

  • Address is generated without registration
  • Incoming messages arrive instantly
  • Free API requires no API key
  • Privacy policy says IP addresses are not stored

Watch out

  • Incoming messages last only 10 minutes
  • Mailbox lifetime cannot be extended
  • Email sending is unavailable
  • Domains are not renewed

Who it suits

Mail.gw suits people who need a temporary inbox for account signups or a testing workflow that automates email confirmation. It is not suited to anyone who needs a lasting mailbox or outgoing email.

Verdict

Mail.gw provides quick, temporary inboxes and a free API for short-lived email confirmation workflows. Its 10-minute retention and lack of sending or domain renewal make it unsuitable as a persistent account.
