Spec score 9.0 #5 of 44 in Temporary email services

What it is

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.

Who it suits

MailDrop may suit developers and privacy-conscious users who need temporary addresses for short-lived sign-ups or verification. Its API also serves users who want to create temporary mailboxes programmatically.

Verdict

MailDrop is built for temporary email rather than keeping account records. Its free API plan and mailbox controls are clearly described, but messages do not persist.
