What Is Open Rate Tracking?
Open rate tracking involves inserting a hidden image (tracking pixel) into your email. When the email service provider (ESP) loads this image, it signals that the recipient has opened and read the email.
Why It’s No Longer Effective:
Inaccurate Data: Microsoft and Google have recently updated their email systems. Microsoft now blocks images from new senders by default, and Google tries to warn users about hidden tracking images (although we have implemented a solution for Google).

Harmful to Deliverability: Our research shows that using tracking pixels can reduce inbox deliverability by up to 70%, even with a custom domain.
