Using the Email Signature Rescue Installer App for Mac OS

mac desktop icon

We know that there's nothing more frustrating than creating a beautiful email signature with our software, only to experience issues when it comes to installing it, no matter how big or small the hurdle may be. Whilst we do try and make the installation process as simple as possible for each and every email client, wouldn't it just be great if your signature could be installed for you? Well now it can!

We've been working hard on our signature installer app over the past few months so that all you need to do is insert your signature key and let our app do the rest for you. What's even better is that not only will it install your email signature for you, it will even automatically update your signature whenever you make changes to it from your Email Signature Rescue dashboard.


How does it work?

Firstly, download our signature installer app for Mac OS X. Once downloaded, run it and select your email client and mail account, then insert your signature key. Our app will then use the signature key to pull in your email signature and install it in your selected email client for you.

Whenever the installer app detects a change to the signature from your ESR dashboard, it will automatically push an update to your e-mail client meaning you'll never have to re-install your signature again.


Which email clients are supported?

  • Apple Mail (MacOS El Capitan, Sierra and High Sierra are supported)
  • Outlook for Mac 2016
  • Outlook for Mac 2011
  • Mozilla Thunderbird
  • Postbox for Mac

FAQ's and troubleshooting

My email signature isn't inserting when I compose an email

My email signature isn't inserting when I compose an email

If your email signature isn't inserting when composing a new email, there's two things you should check.

Make sure your email signature is installed by going to your email client's settings or preferences. If your email signature is not installed then you should make sure everything in the app is correct. If it is and the app isn't installing your signature, please get in touch with our friendly Support Team by clicking help button from your Email Signature Rescue account.

If your email signature IS installed, but isn't inserting into your emails, you'll need to set it as your default email signature for the account which can be done from your email client's settings or preferences.

If none of the above helped you resolve the issue you're experiencing, please get in touch with our friendly Support Team by clicking help button from your Email Signature Rescue account.

My email signature is inserting in an account it shouldn't be

My email signature is inserting in an account it shouldn't be

If your email signature is inserting into another webmail account you have which it shouldn't be then you should double check that you've selected the correct email client within the installer app.

I have multiple businesses and want to use different email signatures, how can I do this?

I have multiple businesses and want to use different email signatures, how can I do this?

Many of our users are running multiple businesses and need to have different signatures for each of their email accounts but aren't sure how to do this. Don't worry though, it's simple.

When using the signature installer app, simply install a signature, then if you require another one, click the Add New Signature button below and follow the same process as you did with your first signature.

My email signature isn't automatically updating when making changes from my ESR account

My email signature isn't automatically updating when making changes from my ESR account

Your email signature will only automatically update if you're using your signature key. If you have inserted the HTML via advanced settings then your signature will not automatically update and will require a re-install each time you make changes.

If you have your signature key inserted, you should check that the key is correct and current with your email signature in your account. Go to your dashboard and ensure the key matches the one installed. If it does, go to the installer app and click Preview Signature, if the signature has updated then it's working correctly and the issue is elsewhere. If it doesn't update then you should get a new key for your signature and insert the new key.
