Mail.tm — Temporary email with a password: the address and password are generated automatically, the inbox lives until you delete it and messages are kept for 7 days. Free API with webhooks, handy for automated form and sign-up tests.
What is Mail.tm
Mail.tm creates a temporary inbox as soon as you open the site and protects it with a password, so a stranger can't read your mail just by guessing the address. That sets it apart from public services like YOPmail.
Official site: mail.tm. Price: free.

Who Mail.tm is for
Anyone who needs a temporary inbox for a few days without strangers reading it, and anyone automating form checks via the API.
When not to use a temporary email
Never register ad accounts, payment services, affiliate network accounts or anything with money on a disposable address: if you lose access, you can't reset the password or pass verification. Use temporary mail for trials, newsletters, gated downloads and testing your own landing page forms.
