CentralMail review
A privacy-focused free mailbox with IMAP, filtering, and OpenPGP support.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
CentralMail is a free personal email service operated by Transcom for solo users and small teams who want an ad-free mailbox with privacy controls. The Free plan provides 1 GB of storage, browser-based webmail, IMAP access, spam and virus filtering for incoming and outgoing messages, and addresses across multiple CentralMail-affiliated domains. Users can also choose Public or Private inbox privacy modes, with Private mode limiting delivery to an allow-list. Native access is web-based, while IMAP supports phone and desktop mail clients.
Privacy is the service's clearest differentiator. Optional OpenPGP signing and end-to-end encryption give users a way to add message authenticity and confidentiality, with additional compatibility for PGP and S/MIME. The filtering layer covers both incoming and outgoing messages, helping keep spam and viruses out of mail flows. These controls make CentralMail a strong fit for people who value privacy and want a free mailbox without advertising, rather than a broad productivity suite.
The published Free plan costs £0 per month and includes the core mailbox, filtering, IMAP, and encryption options; there are no paid tiers presented alongside it. Its narrower platform model may be less convenient for users seeking a full native mobile and desktop email experience, while the 1 GB storage limit may constrain heavier mailbox use. Choose CentralMail for a privacy-oriented free address with standard mail-client compatibility. Consider another service if you need more storage, custom-domain support, aliases, or a wider platform offering.
