Email Tracking

With Mailbutler’s Email Tracking feature, you can get important information about all of your sent emails. See when and how often your emails were opened, and where your recipient was when they opened it, as well as which device they opened your message on.

Send Later

Don’t want to send your email immediately? With Mailbutler you can write your email now and send it at a specific time in the future. This allows you to work on your emails when you have time and send them at the optimal time. Perfect for people who like to work late at night or communicate with clients in different time zones and don’t want to appear unprofessional.


Mailbutler’s signature generator provides a collection of premade email signature templates into which you can simply enter your details and get started with immediately. You don’t need any design or coding skills, and all our signatures are fully responsive, so they look great on any device. For those who want a little more control, you can customize fonts, colours, logos and more to match your corporate identity.

Undo Send

Sent a message and realised you’ve made a mistake or forgotten an attachment? With Mailbutler’s Undo Send feature you can recall a sent email before it’s been delivered and correct any errors you may have made. All your sending emails are stored in your inbox until you’ve made any required edits, and you can set your own delay times so give yourself plenty of time to check over your emails.
