1) Tap the “Email Signature Capture” button on CleanUpDuplicates app home screen.
2) Tap on the 'Connect an email' button and choose to connect with your Microsoft, Exchange (Coming Soon) or Google (Business account).
Once your account is connected, app will scan any available emails from the past 30 days to look for signatures. Additionally, on an ongoing basis, the app will scan for signatures in any new emails you receive -- and if found, will be suggested as a new contact.
To review your captured signatures, press the Email Capture button on your CleanUp Duplicates app home screen. By default, the list will show signatures captures from all connected accounts (Gmail and Microsoft). You can tap the All Signatures drop-down at the top of the screen to filter the list by each connected email account.
If you ever need to connect additional accounts, press the All Signatures drop-down button after tapping on the Email Capture button, press 'Add Email'
