Frequently Asked Questions

Everything you need to know about Seenify email tracking, read receipts, privacy, and compatibility.

What is Seenify?

Seenify is an email tracking platform and lightweight browser extension that provides real-time email open tracking, email read receipts with double checkmarks, recipient-level tracking, and instant notifications. It currently integrates seamlessly with Gmail.

What is email tracking?

Email tracking is a method used to monitor when sent emails are opened by recipients. It helps senders confirm message delivery, understand engagement timing, and follow up effectively.

How can I know if someone opened my email?

With Seenify, you see visual double checkmarks (✓✓) right next to your sent emails in Gmail that turn blue upon opening. You also receive real-time desktop notifications the exact second the recipient opens your email.

How does Gmail email tracking work?

Once you install the Seenify extension, it automatically integrates into your Gmail composer. When you send an email with tracking enabled, Seenify appends the tracking pixel and monitors open activity directly in your Gmail interface and extension dashboard.

Does Seenify provide email read receipts?

Yes. Seenify provides real-time email read receipts using WhatsApp-style double checkmarks inside Gmail, detailed timestamps, and instant popup notifications.

Can Seenify track multiple recipients?

Yes. Seenify supports recipient-level and multi-recipient email tracking, allowing you to see individual open events when sending emails to multiple contacts.

How accurate is email open tracking?

Seenify provides high-precision email open tracking based on direct image load requests. If an email client blocks remote images or uses certain prefetching proxies, open detection occurs when images are loaded by the recipient.

Does email tracking work with Gmail?

Yes. Seenify is fully optimized for Gmail on Google Chrome, Mozilla Firefox, Brave, and other Chromium browsers.

Does Seenify support Outlook?

Seenify currently supports Gmail, with future platform support planned for Microsoft Outlook, Yahoo Mail, and additional email clients.

Is Seenify free?

Yes. Seenify is 100% free with no hidden paywalls for core email tracking features, double checkmarks, and real-time open notifications.

How does the Seenify tracking pixel work?

The Seenify tracking pixel is a transparent 1x1 GIF generated with a unique cryptographic token for each email. When the email is rendered by the recipient, the image requests the token from the Seenify server, recording the open timestamp without altering your email layout.

Does Seenify read my email content?

No. Seenify never reads, parses, stores, or sells the body content, attachments, or text of your emails. Seenify operates under strict Google API Services Limited Use compliance and only processes open metadata.

Provide real-time email read receipts and double-check tick indicators in Gmail.
Send native desktop notifications when an email is opened.
Display your tracking activity feed inside the extension popup UI.

Technical Disclosure

1. How Tracking Pixels Work

Seenify uses a standard, lightweight 1x1 transparent GIF image embedded in outgoing emails you choose to track. When the recipient's email client displays the email, the image is requested from our server, generating a timestamped open event.

2. Browser Local Storage

We use Chrome's native chrome.storage.local API to save your extension settings locally on your machine. No persistent tracking cookies are placed on your web browser.
