Use opens to guide timing
If an email was opened today, that often means your message is top of mind. That can be a better follow-up moment than sending blind three days later.
Open tracking is most useful when you use it as decision support, not as a vanity metric. These best practices help Gmail users get better follow-up timing without overreacting to noisy signals.

One open should not trigger five follow-ups. Use the signal with context: who the recipient is, what stage the conversation is in, and how recent the last reply was.
When you follow up after an open, bring something useful: a pricing clarification, a case study, a next step, or a short answer to a likely question.
Email open tracking depends on recipient mail client behavior and image loading, so it should be treated as a strong signal rather than an absolute truth.
