criptext.com - Email Domain Verification & Deliverability Report

Criptext is a privacy-focused email service that emphasizes end-to-end encryption using the Signal Protocol. The service was designed to give users full control over their email communications, with features including message expiration, read receipts, and the ability to unsend messages. Criptext stores encrypted emails on user devices rather than on central servers.

criptext.com supports standard email authentication protocols including SPF and DKIM for outbound messages. DMARC policies are published for domain protection. As a privacy-first service, Criptext's architecture prioritizes end-to-end encryption, meaning messages between Criptext users are encrypted by default.

The criptext.com mail servers handle recipient verification at the SMTP level and reject messages to nonexistent addresses. The domain does not operate as a catch-all. Given the privacy-oriented architecture, inbound mail handling follows standard SMTP conventions with additional encryption processing for incoming messages.

When sending to criptext.com users, ensure your domain has proper SPF and DKIM authentication. Messages from external senders are delivered through standard SMTP and encrypted at rest on the recipient's device. Maintain standard deliverability practices including clean lists and proper authentication for consistent delivery.
