Question 1

What is MailBlinker?

Accepted Answer

MailBlinker is a free, self-hosted, unbranded email tracker that notifies you instantly via Telegram whenever your sent email is opened. It includes anti-cache protection against Gmail and Apple Mail image proxies, and provides device and location telemetry.

Question 2

Why is MailBlinker a better alternative to Mailtrack?

Accepted Answer

Unlike Mailtrack, MailBlinker is completely free, 100% self-hosted on your own infrastructure, adds zero 'Sent with Mailtrack' signatures or branding to your emails, and sends instant push alerts directly to your Telegram chat.

Question 3

How does MailBlinker prevent false opens from security bots?

Accepted Answer

MailBlinker combines sub-3-second latency analysis with CrawlerDetect and user-agent parsing to identify and filter out automated corporate security sandboxes (such as Mimecast, Proofpoint, and Barracuda), ensuring you only get alerts for genuine human opens.
