SimpleLogin vs TMailr

SimpleLogin creates email aliases that forward messages to a mailbox while keeping a user's real address hidden. Users can reply to messages or send mail from an alias. Aliases can be created with a subdomain or catch-all domain, and users can bring their own domain. With PGP enabled, messages are encrypted with the user's PGP key before forwarding. Accounts support TOTP and/or WebAuthn two-factor authentication. SimpleLogin says its components are open source and can be self-hosted. It lists Chrome, Firefox, and Safari extensions, plus iOS and Android apps, including Android through F-Droid. The Free plan costs nothing and includes 10 aliases, one mailbox, and unlimited bandwidth; users cannot create more aliases after reaching the cap. Premium costs $36/year or $4 billed monthly, and includes unlimited aliases, custom domains, and mailboxes, plus PGP encryption. Free and Premium plans include the corresponding Proton Pass features. SimpleLogin says it joined Proton in early 2022.

TMailr combines receive-only temporary inboxes, masked forwarding aliases, email deliverability checks, and a developer sandbox on the web and through an API. Temporary inboxes use private links, receive mail only, and disappear when they expire. Free inboxes last 60 minutes by default, can be extended to 24 hours, and hold up to 50 messages; Pro inboxes are described as effectively unlimited and remain active while subscribed. Masked aliases forward messages to a real mailbox, can be paused or blocked separately, and keep the forwarding address out of TMailr pages and API responses. Deliverability tools include Gmail inbox tests, domain checks for MX, SPF, DMARC, MTA-STS, and TLS, plus header, address, and DMARC tools. Developers get test and live keys, JavaScript examples, polling, and signed webhooks. Incoming HTML is sanitized, remote images are blocked until requested, links show destinations, and attachments are virus-scanned; executable files are refused.
