How to Parse Gmail Signatures with AI (GDPR-Compliant Guide)

Gmail signatures are goldmines: phone numbers, job titles, domains, and social links that rarely make it into Google Contacts. Here’s how to extract them automatically without breaking trust or compliance.

Why signatures matter

• They contain verified contact data straight from the sender.
• They capture info that CRMs miss (LinkedIn URLs, personal phone numbers).
• They’re easy to parse with modern AI—if you do it responsibly.

AI parsing workflow (Mail2Sheets)

1. Connect Gmail via OAuth → Mail2Sheets only touches the specific date range you choose.
2. Our AI reads email bodies/signatures, extracts fields (Name, Organization, Website, Job Title, Phone).
3. Everything writes straight into your Google Sheet. Parsed data is deleted from our systems immediately.

GDPR best practices

• Minimise scope: only process the timeframe you need.
• Delete intermediates: Mail2Sheets does this automatically after writing to Sheets.
• Honour access requests: your sheet is easy to search/export if a contact asks for their data.

Manual option

For low volumes, you can copy/paste signatures into a Sheet and run a regex to split phone numbers/domains. It’s tedious, which is why agencies automate it.
