Launching Mid 2026

Email Intelligence That Respects Encryption

Email tracking with read receipts, smart tagging, and a tracking dashboard — built for S/MIME and GPG without breaking cryptographic integrity.

What You Get

Everything you need to track email delivery and engagement — without compromising security.

Read & Open Receipts

Know when your emails are opened. Delivery and read signals without proxy servers or message rewriting.

Notes on Emails

Attach private notes and context to any sent message. Your notes stay local — never on our servers.

Smart Tagging

Organize sent messages with intelligent tags. Filter and find tracked emails instantly.

Tracking Dashboard

A clean command center for all your tracked messages. Status, timestamps, and engagement at a glance.

Built for Signed & Encrypted Email Tracking

Most email trackers break S/MIME and GPG signatures because they modify the message body after signing. SENTxt™ works differently — tracking is injected before the cryptographic seal, so your signatures stay valid and your encryption stays intact.

S/MIME & GPG Encrypted Encryption remains unbroken

Privacy by Design

SENTxt™ is built on principles, not compromises.

Email content is never stored on our servers

Sensitive metadata stays local-first

No proxy servers, no message rewriting

Not spyware, not surveillance, not marketing analytics
