MailFlusher is an anonymous email forwarding service for creating separate email addresses for different websites, newsletters, and online services. It is built to protect a real address from spam, data breaches, and unwanted marketing while keeping control over who can contact that inbox.
The service lets users create unlimited aliases, forward incoming mail to a real inbox, and deactivate or delete aliases when they are no longer wanted. Messages sent to an alias can be replied to and sent from through the alias address, and the sender does not see the real email address. MailFlusher also supports GPG/OpenPGP encryption for forwarded mail, including attachments and optionally the subject line, along with blocklists, catch-all and on-the-fly aliases, smart filtering rules, multiple recipients per alias, tracker and pixel stripping, Ghost Inbox mode, outbound webhooks, and a REST API for managing aliases, recipients, and domains.
It works with Gmail, Outlook, Apple Mail, ProtonMail, Tutanota, Yahoo, iCloud, and any standard email client or other email provider. The page also says it is hosted in Germany and the EU, GDPR compliant, and has no tracking. Its intended users include privacy-conscious individuals, online shoppers, freelancers, and professionals.
In the Email & inbox space, MailFlusher takes a focused approach. Protecting users from spam and data breaches by providing disposable email aliases and anonymous forwarding. It is built as a consumer product for privacy-conscious internet users. There is a free tier, and paid plans start at $3. It runs on the web, embeddable surfaces, and API.
MailFlusher builds and maintains MailFlusher, and it first shipped in 2026. Key capabilities include email aliasing, anonymous forwarding, and GPG encryption. It exposes integrations via a public API.
