Fastmail Masked Email vs Mailo

Fastmail Masked Email creates a random email alias for each login, letting users give a site an address other than their real one. Using separate aliases can make it harder for companies to connect accounts for tracking. Messages to these addresses arrive in Fastmail; a masked icon marks them, and opening a message shows the label assigned to the address. An alias can be turned off if it starts receiving spam, which Fastmail says may help identify who exposed it. Users can connect Masked Email with 1Password or Bitwarden, or use their own domain; Fastmail says a custom domain is less anonymous than its shared domain but makes addresses portable. A JMAP extension lets apps read and manage addresses, though pending API-created aliases are deleted after 24 hours and do not appear in the interface. Fastmail supports two-step verification and passkeys and encrypts stored data and communications. Its own apps do not offer end-to-end encryption. Plans start at $4 a month, and a 30-day trial is available; there is no free plan. Access is available on Android, iOS, Linux, macOS, Windows, and the web.

Mailo is an email service available on the web and through Android and iOS apps, with calendar, address book, cloud and sharing services. Its free plan includes 1 GB of email storage, 500 MB for documents and photos, five aliases, advertising banners, and IMAP4 and EAS access. Premium is listed at €1.50 per month and expands the mailbox to 20 GB, with 5 GB for a virtual disk and photo albums and up to 100 aliases. Premium also removes webmail advertising, supports attachments up to 50 MB and provides POP3 or IMAP4 access. It includes a lifetime email address, and the offer can be activated for one to five years. Mailo says it stores data in France, does not use or sell it, and does not read messages; listed features also include end-to-end encryption and custom domains. Migration tools can retrieve messages, contacts and events from an old provider and set up forwarding. Mailo says it offers responsive, personalized support in English.
