Top Gmail Lead Extraction Tools for Agencies (2025 Edition)
Agencies live or die by the quality of their inbox. Here’s a quick rundown of the Gmail lead extraction tools we see agencies using—and when Mail2Sheets is the right choice.
1. Mail2Sheets (best for Sheets-first workflows)
- AI parses signatures, subject lines, and attachments in one click.
- Outputs a clean spreadsheet with ready-made CRM columns.
- Never stores inbox data (GDPR-compliant), perfect for regulated clients.
2. Zapier + Gmail + Formatter
Great if you already pay for Zapier, but parsing signatures requires multiple tasks and can get pricey quickly.
3. Google Workspace Add-ons
Extensions like Yet Another Mail Merge help with outreach but still require manual data cleanup.
4. IMAP data dumps
Developers sometimes write scripts to export IMAP data, but maintenance overhead is high and there’s no AI cleaning.
5. CRM-specific connectors
Tools like HubSpot’s Gmail integration capture prospects, but they only store “contacts” you manually add.
For agencies that want an instant Gmail lead extractor feeding Google Sheets (and then CRMs), Mail2Sheets wins on price, speed, and accuracy. Try it free and keep every agency inbox organized.
