What MailDrop is

MailDrop provides temporary disposable email inboxes for sign-ups, verification messages, downloads, trials and forms. Opening an inbox does not require an account, phone number or personal information. Users can set a custom prefix and choose from several domains; inboxes refresh every 30 seconds and can receive HTML email, verification codes and attachments for browser preview or download. Messages are kept temporarily and then deleted automatically, so MailDrop advises against using temporary inboxes for long-term accounts such as banking. A REST API can create temporary mailboxes and read incoming email. API keys authenticate requests, and claimed mailboxes can be read only by the key that created them. When a quota runs out, the API returns HTTP 429 and includes quota state in response headers. The free API plan is described as a permanent trial with no credit card required. MailDrop lists web and API access and says the service is available in seven languages. Paid API plans start at $5 a month.

Getting started

Open the MailDrop website.
Set a custom email prefix and choose one of the available domains.
Use the inbox in your browser; it refreshes every 30 seconds.
For API access, create requests with an API key in the Authorization or X-API-Key header.
Choose an API plan based on request and mailbox quotas.

Verdict

MailDrop covers temporary inbox use in a browser and through a REST API, with a free API tier and paid quotas. Its automatic message deletion makes it a poor fit for long-term records.
