Universal Mailer overview

Note: While the software is classified as freeware, it is actually donationware. Please consider making a donation to help support development.

Universal Mailer is a Mail.app plugin that solves some issues when sending emails. It removes ATT00001.htm files, it correctly formats messages with attachments and inline images, and offers an option to set the default font for outgoing messages.

When enabled, Universal Mailer is able to correctly format outgoing emails, so that even after Exchange EWS filtering they retain the original format.

The plugin runs in the background without interfering with your work: all you have to do is set a default font for outgoing emails and write your emails as usual. When you hit the Send button, Universal Mailer checks the email for you and modifies it as needed.

On may Mac I'm getting an error message saying that this plug-in (v. 2.1.5) is incompatible with Mail 7.1 and 7.2. Can that be fixed?

2.1.5 works great here. Allowed me to change font of outgoing mail which has been a lacking setting in mail.app since about OSX 10.4. Not sure what Apple was thinking there and why this is not a standard option in mail.app. Current MU download link for stable broken: says „no file“ or goes to a dead github pages which does not exist: https://www.macupdate.com/download/40596/universal-mailer/2.1.3/UniversalMailer-v2_1_3.zip/1389118292 Project does still exist though and an updated version 2.1.5 can be found here: https://universalmailer.github.io/UniversalMailer/download.html
