I like the ease of use. The availability of free version for testing and that it doesn't let the recipient know that the email is being tracked.

GetNotify is a website that helps you gain that extra edge on your emails and helps you find out whether your recipient has opened your email or not. It could be used by virtually anybody for any purpose. However, GetNotify has proved to be very useful for my Shopify Business. Here's what I like about it the most:- 1) Upgrades: GetNotify is basically free to use, however, if you need to send out more emails, you can always purchase more credits. For those who choose to use this professionally, I'd say it's completely worth it. 2) Tracking: GetNotify enables you to track Links within your e-mails. 3) Recipient Data: Not only will you get to know if your email has been opened or not, but you can even get other details such as how long your recipient has spent reading your e-mail. For those of you who want to delve into technical specifics, you can even get your recipient's IP Address, location, browser information and even what OS he/she is operating on. 4) Email Marketing: You can use GetNotify to collect useful metrics about your E-mail Marketing campaigns make informed decisions. 5) Go Incognito: You recipients won't know that the email is being tracked ;) ;)
