MailDrop vs Tempr.email

MailDrop provides temporary email inboxes for sign-ups, verification messages, downloads, trials, and forms. You can open an inbox without an account, phone number, or personal information, choose a domain, and set a custom email prefix. Inboxes refresh every 30 seconds and can receive HTML messages, verification codes, and attachments for browser preview or download. Messages are retained only temporarily and then deleted automatically, so the site advises against using the service for long-term accounts such as banking. A REST API can create temporary mailboxes and read incoming email. API keys authenticate requests, and a claimed mailbox can be read only with the key that created it. When a quota is used up, the API returns HTTP 429 and quota details in response headers. MailDrop is available on the web and through its API, and the site says it is available in seven languages. The Free plan costs nothing; paid plans include Starter at $5 a month, Pro at $15 a month, and Business at $49 a month.

Tempr.email provides disposable email addresses for receiving messages without giving out a personal inbox address. Users choose an alias and domain, then read incoming mail without registering. The service lists 61 domains, with more added regularly, and accepts text and HTML email, including file attachments. Messages are automatically deleted after 30 days, though users can delete them sooner. A free account adds password protection for selected mailboxes, custom domains, saving or printing messages, header viewing and bookmark access. Premium access enables sending, forwarding and replying, as well as RSS and ATOM notifications for new mail. Tempr.email is a web service that also works in a responsive mobile browser. Listed use cases include registrations, downloads, surveys, short-term test accounts and newsletter testing. The service advises using a regular address for banking and important long-term accounts. It cautions that complete anonymity cannot be guaranteed, and that mailbox security partly depends on alias guessability; password protection also has limits. The free plan costs nothing and retains messages for 30 days.
