How do you add a note to an email?

Adding a note to an email is simple with Mailbutler! After you download Mailbutler, you’ll be able to open the Mailbutler Sidebar. In the Sidebar is a yellow button with a note icon, and clicking that lets you add a note to an email or contact whenever you have an email or contact selected. You can even share this note with other Mailbutler users! It really is as easy as that.

Is there a notes feature in Gmail?

The native Gmail application does not have an integrated notes feature. To add notes in Gmail, you have to download an extension. There are a few options on the market, but (and maybe we’re a little biased) we think Mailbutler is the best option – mostly because you also receive a wealth of other features which work well together, such as the Tasks feature, with which you can also add to-dos to emails and contacts, along with your notes.

Why should I work with the Mailbutler Notes feature in my inbox?

The Mailbutler Notes feature is a great way to keep on top of any important information you don’t want to forget. You can attach notes to emails and contacts and share them with all of your team members, so everyone is always up to date. You could add information about a client, or notes on a presentation, and share them with the relevant people, so you all remember everything you need to. It also works well in conjunction with our Contacts feature, which lets you add custom information to your email contacts, and our Tasks feature, with which you can attach actionable to-dos to emails and contacts.

Can I sync Mailbutler notes with third-party applications?

Yes you can! Mailbutler Notes can be integrated with OneNote and Evernote, and our other features integrate with many more different apps. You can sync your Mailbutler notes to these applications, meaning a note created in Mailbutler will show up in, for example, Evernote. Check out our Support Center article for more information on integrations.

“You know when you want your mail program to do that bit more, like easily schedule your emails, note that you've used the word attached in the copy but haven't attached anything, or help you know if your recipient has actually opened your last message? Mailbutler makes it happen.”
