Version 1.7.6 adds a key feature for me: the ability to start with an existing signature to create a new one. The latest version can use existing signatures as a template Please feel free to contact us at with any additional feedback! We don’t replace existing signatures, but you can delete the old one yourself if you choose. Also, you CAN edit existing signatures using the selection box at the bottom. Hi - thanks for the feedback! We’ll consider it for a future update to improve the UI. Also it should ask for permissions first, that way you have access to load a signature at the start rather then having to create a signature first. Developers should swap this out for something more inline with the UI. Only lasts a few seconds, but this sort of looks like the app is not working right. I also get a mac spinning wheel on submit for new signature. Otherwise you need to go back to your Signatures in MacMail and update and move around signatures. Would give 5 stars if we could replace existing signatures as well. This app makes adding new Signatures much easier then having to access the MacOS files directly, but this only allows for adding new signatures.
