Seenly
Know the exact moment
your email is read.
Seenly slips an invisible pixel into the emails you send from Gmail. When your recipient opens it, you get a real-time ✓✓ read receipt — right in your Sent list and inside the thread.
No credit card · Works with your existing Gmail · Read receipts update live
Read receipts in three steps
Write like normal
Compose in Gmail exactly as you always do. Seenly works quietly in the background — nothing new to learn.
Hit Send
Seenly embeds a tiny invisible pixel and starts tracking. A subtle “Sent with Seenly” footer keeps things transparent (toggle it off anytime).
Watch for ✓✓
The instant your recipient opens the email, a ✓✓ and “read 2m ago” appears in your Sent list, your thread, and the Seenly popup.
Everything you need, nothing you don't
Real-time, no polling
Powered by Firestore live listeners — receipts flip to ✓✓ the moment an open happens.
Unlimited & free
Track as many emails as you want. The free plan has no monthly cap.
Smart proxy filtering
Gmail pre-fetches images at delivery. Seenly ignores those so you only see real opens.
Private by design
We store the subject, recipient, and open times — never the body of your email.
Repeat-open counts
See not just if but how many times an email was opened, and when it was last read.
Built to localize
Ships with i18n scaffolding — English today, your language next.

Your email is yours
Seenly is intentionally minimal about data. We only ever store what's needed to show you your own read receipts: the subject, the recipient, the send time, and open events. We never read or store the contents of your emails.
