Fastmail Masked Email

Free plan: No
Mailbox storage: 5
Attachment limit: 50
Purpose: Masked Email creates a unique address for each login to keep your real address private and make addresses harder for companies to link for tracking.
Disable addresses: You can turn off a Masked Email address if it starts receiving spam, and Fastmail says this can help identify who leaked it.
Integrations: Fastmail says Masked Email can connect with 1Password and Bitwarden for smoother signups.
Custom domain: You can use your own domain for Masked Email, though Fastmail says this is less anonymous than using its shared domain and makes addresses portable.
Address behavior: Masked Email addresses are random aliases intended for logins, and Fastmail suggests using a new one for each site account.
Inbox identification: Messages to Masked Email addresses display a masked icon, and opening one shows the label assigned to that address.
API: Fastmail provides a JMAP extension that lets apps read and manage a user's Masked Email addresses.
API limit: Pending masked addresses are automatically deleted 24 hours after creation and are not shown in the Fastmail interface.
Security: Fastmail says data is encrypted at rest and communications are encrypted in transit, with support for TLS 1.3 and Perfect Forward Secrecy.
Account protection: Fastmail supports two-step verification and passkeys, and says it conducts internal security audits and runs a bug bounty program.
Encryption limit: Fastmail does not offer end-to-end encryption in its own apps, but says customers can use PGP or S/MIME in many third-party apps.
Price from: $4/mo
