Clean bounced e-mails out of your CRM

Contacts whose e-mail bounced or who left the company, marked in your CRM after your approval.

  • On a schedule: Every Monday at 7:00
  • Asks you first
Use in CuiarRun from your AI agent

What it does

The task

Search Gmail for bounce messages and automatic replies since the last run that say the address does not exist or the person left the company. Match each one to a contact in HubSpot. For each match, prepare these changes: set the e-mail status to Invalid, and add a note with the bounce text and the new contact that the reply names, if any. Show me the list of changes, and ask me before you save them. Do not delete any contact.

  • It works in Gmail and HubSpot, in the workspace you pick, and signs in with passwords from your Cuiar vault.
  • As a routine it runs every Monday at 7:00 (cron 0 7 * * 1).
  • It stops for your approval before it sends, posts, pays, books or changes a record.

What you get back

An example run. Your run uses your own data.

Bounces and automatic replies since 26 October: 17

Matched to HubSpot contacts: 15

Prepared changes:

  • 9 contacts: e-mail status Invalid (the address does not exist)
  • 6 contacts: left the company. Note added; 4 replies name a new contact.

Example: Ben Achterberg, Corvid Freight. Reply: 'Ben has left. Please contact Lisa Moreau, Head of Procurement.'

Not matched: 2 addresses with no contact in HubSpot

Waiting for your approval to save. No contact deleted.
