Filter Out Free Email Addresses Automatically

B2B outreach to Gmail and Yahoo addresses has extremely low ROI - they rarely take action. Notis automatically identifies free email addresses, so you focus only on corporate domains.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Verify Free Email Account

Tool to detect if an email is from a free email service provider. Use after confirming the email format.

Why this helps

Free email addresses in your B2B list dilute your outreach effectiveness and waste time on low-value contacts

  • Automatically identify all free/consumer email addresses in your list
  • Keep your prospect list focused on corporate domains with decision-making power
  • Improve conversion rates by filtering low-ROI email types

Setup

Build it in a few focused steps.

  • 1Connect Clearout to Notis
  • 2Tell Notis: 'When an email appears, identify if it is from a free provider like Gmail, Yahoo, or Outlook'
  • 3Set your trigger source - Slack mentions, email forwards, or CRM webhook
  • 4Notis will check and report each email against Clearout's provider database
  • 5Test with any Gmail address to verify detection works correctly

Questions about this workflow

What counts as a 'free' email?

Gmail, Yahoo Mail, Outlook, AOL, and other consumer-facing email providers. Corporate domains (company.com) are not flagged.

Can I still contact people with free emails?

Yes - Notis flags them so you know the email type. You decide whether to contact them. Some founders contact free emails if the contact has high value.
