There are a few things that they have that I really like. I was wondering if it is something that you will be adding:

1) Apple Mail plugin. I am an email power user. I have using the browser for emails. Will you support an Apple Mail plug in? Mailbutler also has a Chrome extension, but I don't need it since they support Mail.app with this plug in.

2) Mailbutler also supports unlimited email addresses. It does not have to be a Google email either. I have both Google and IMAP so this is useful for tracking all of my link clicks and opens.

3) Undo Send. I can set an Undo send. Basically it is a timer that delays the email. Mine is sent for 10 seconds so I can easily stop it when I remember that I made a mistake. This is not the same thing as scheduling an email - which they have as well.

There are lots of other features that Mailbutler has, however, #1 and #2 above are most important to me.

Looking forward to your response. Thanks
