Send Companion


Send Companion is an App Store approved and privacy-aware extension for Apple Mail on macOS Monterey (12.0) and higher, with the following features:

  • Do you often write the same email fragments?
    AutoText saves your composed (localized) email snippets inside a convenient toolbar to reuse it over and over again. Just compose an entire email with a few clicks.
  • Wish you ever had a second chance? With Review Alert you have!
    Review Alert delays your send action, allowing you to briefly review your email for the most common mistakes, like typos or sending the email from the wrong account.
  • Based on keywords you define, Attachment Reminder will remind you of a missing attachment.
    This allows you to add the attachment even after you have pressed the send button.
    Never ever send a second email with "and now with attachment...".

User Reviews

You’ll never utter these words again if you use Send Companion. The plug-in integrates seamlessly with Apple Mail, allowing you to configure the level of review you need. Attachment Reminder will scan your e-mail for keywords which might indicate that you intended to attach a file, such as “attachment,” “photo,” or “PDF”. The keywords can be user-defined, so the flexibility is virtually infinite.

Works exactly as intended.

I’ve been waiting for this for ages! jshutchinson


Does exactly what I need it to do and it stays completely out of the way until I need it.

No learning curve whatsoever. Great! Steve K


I use several email accounts from within Mac Mail. A big problem with this is that occasionally, when in a hurry, I don’t always check the “from” field and sometimes send email from the wrong account. This can be embarrassing, so when I found Send Companion, I was eager to give it a try.

It does exactly what it promises without fuss David-F


The ability to define your own keywords is definitely a plus and the software has worked the few times that I’ve tried it out.

Thank you!!! olaf-bininda
