Mail Seen Pulse - Email Open Tracker

Ever hit send and wondered "did they actually read it?" Mail Seen Pulse answers that quietly, inside Gmail, the way WhatsApp shows ticks. While composing, click ✓ Track, then send as usual. Next to each email you'll see: • ✓ one grey tick – sent from your side • ✓✓ two grey ticks – reached the recipient's mailbox • ✓✓ two green ticks – they opened it A gentle desktop notification tells you the moment someone opens your email, and the built‑in dashboard keeps your full history: who opened, how many times, and when. Ticks appear in your Sent list, inside conversations, and next to each message — so you never have to open a dashboard to know. Why people keep it installed: • Free forever — no account, no subscription, no watermark, no upsell. • Works with any recipient: Gmail, Outlook, Yahoo, school or company addresses. Tracking happens when their mail app loads the message, so they don't need anything installed. • Your own views never count. Reading your own Sent mail can't fake an "open". • Replies are tracked separately from the original email, so threads stay honest. • One‑click CSV export, encrypted backup & restore, bulk delete. • Light & dark theme; everything is stored on your computer first. Honest limitations (please read before installing): • The compose button works in Gmail on the web (mail.google.com) in desktop Chrome/Edge/Brave. It does not run inside mobile Gmail apps or other webmail's. • Tracking relies on the recipient's mail app loading images. If their setup blocks remote images (some corporate filters) or they read with images off, an open can't register until images load. • Apple Mail's "Mail Privacy Protection" pre‑loads images privately, so it can report an open before a human reads. No tracker of any kind can distinguish that. • Cached or offline views can delay an open by a few minutes; very old emails sync hourly, then daily. • This is a visibility tool, not a legal delivery receipt. If Mail Seen Pulse saves you from chasing "did you get my mail?", the ☕donate button keeps the free server running — donating is entirely optional and changes nothing in the app.
