While Pipedrive doesn't offer a direct connection to tools like SignatureSatori, you can still make use of the signatures you created there in a few easy steps. Please note that this process has to be handled by individual users and has to be repeated in case of signature change.
Go to https://www.signaturesatori.com/app/user, log in with your work account and scroll all the way until you find the Download HTML option.
Click on it and open the saved file in your browser. Select all the content (you can use Ctrl+A on Windows or Command+A on Mac) and copy it.
In Pipedrive, go to Personal preferences > Email Sync > Signatures. Then, click “+ Add signature”.
A pop-up window will appear, copy the signature there:
Save the changes and that's it!
