Email Intelligence That Respects Your Privacy
Email tracking with read receipts, smart tagging, notes, and a clean dashboard — private by design, running entirely on your Mac.
What You Get
Everything you need to track email delivery and engagement — without compromising your privacy.
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.
How SENTxt Works
Other tools route your outgoing mail through their own servers to track it. SENTxt™ works differently — everything runs locally on your Mac, so your email goes straight to your own mail server and never passes through ours.
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
