What Mail.gw is
Mail.gw provides temporary email addresses through a website and an API. It generates an address automatically, without registration, and says incoming messages arrive instantly. Mail.gw is free, with its Free plan priced at $0. Incoming messages remain in the mailbox for 10 minutes, and that period cannot be extended. The service does not let users send email. Mail.gw describes the service as anonymous; its privacy policy says it does not store IP addresses and that temporarily stored emails and data are permanently deleted. The FAQ says the address and emails are deleted after 10 minutes. Suggested uses include registering for online accounts and sharing private thoughts online. The free API creates temporary email accounts and is intended to automate email confirmation during testing. It requires no API 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 configured with Mail.gw’s base URL. Notifications use Mercure server-sent events, not webhooks. Support options include email, Discord, and Telegram. Mail.gw does not renew its domains and recommends Mail.tm for a constant account.
