Track email opens in Gmail

This tutorial explains what to watch, how to interpret an open event, and when to send a follow-up after a Gmail message is opened.

What to monitor

Focus on whether the email was opened, when it was first opened, and how that timing relates to your last touchpoint.

A simple decision rule

If the email was opened and there is no reply after a reasonable delay, send a short follow-up that adds one new piece of value or clarity.
