Its small but helpful actions such as: 1) Snooze emails 2) Program emails sending 3) Create notes on Evernote directly from Mail. 4) Quick access to GIF 5) Improved signature details (responsive)

Mailbutler helps me sort and prioritize my mail. I especially like the ability to send mail at a specific date/time and to get reminders to follow up on certain emails. You can also use it to sign emails with your digital links in an attractive way.

Creating email templates and use them over and over again. I use it for the FAQ people send me. The only thing I need to do is personalize them. Another great addition is the notification an email opened. The last great feature is I never forget to add an attachment again; usually, you will refer to it with a word. You can set different words and when you want to send the email it recognizes the word and reminds you to add the attachment.
