GhostRelay vs TMailr

GhostRelay is a web service that creates email aliases and forwards their messages to a real inbox. Users can make random or custom aliases, monitor them, and disable or delete them from a dashboard. The free plan costs nothing, requires no credit card, and allows up to 20 aliases with unlimited forwarding, custom names, and enable or disable controls. Forwarded messages preserve the Reply-To header, and the service supports replying from an alias. Mail can be sent to any receiving address, including Gmail, Outlook, Yahoo, ProtonMail, and iCloud. Disabled aliases reject incoming messages and return a bounce to the sender. GhostRelay says email is processed in memory without disk or database storage and content is not retained. It describes TLS 1.3, AES-256, bcrypt hashing, and signed JWT authentication. Custom domains and a browser extension are available; mobile apps and a public API are not.

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.
