The feature lets me know as soon as my sent email is opened by the receiver. I follow up any emails that have been marked as opened. What a great feature!

Part of my job has me sending cold emails. When I follow up with potential clients, I always adjust my follow-up email depending on whether the person has read the previous email or not.

The Tracking feature is my favorite feature. It integrates seamlessly with notifications, letting you know that your customers and coworkers are on the topics you are still missing. Especially for multi-project managers with a lot of emails super helpful!
