In their own words
Mail.cx
Mail.cx provides short-lived inboxes for developers, QA teams, and product teams checking account verification, transactional messages, notification pipelines, or application integrations. It only receives email; it does not send it. A web inbox can be opened without signup by choosing a username or generating one, and server-sent events can push arriving mail to the browser. Its REST API supports long-polling, retrieval of parsed or raw email, attachment downloads, and event delivery. API use is limited to 10 requests per second per token; long-polling allows one concurrent wait per token and 10 per address. Free messages are automatically deleted after one hour, while Pro messages are retained for 72 hours. The Free plan is free, and Pro is $9.90 a year. A separate pricing note lists paid plans from $4/mo. Mail.cx says connections use TLS and that passwords and API tokens are stored as hashes. Its terms caution that message retention and recovery are not guaranteed, and advise against relying on the service for critical, sensitive, or business-essential communications.
MailDrop
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.
