Email Bounce-Back Recovery Agent

Turn Bounced Emails Into Updated Contacts

Email lists decay fast — people change jobs, companies rebrand, and addresses go stale. When a bounced email comes back, most teams either delete the contact or add it to a manual research queue that never gets worked through. This agent turns each bounce into a research task that gets done.

When a bounce-back is passed to the agent, it pulls out the contact’s name, the email that failed, and any available context like their former title or company. It then researches the contact across the web and LinkedIn to find where they’ve moved — their current company, new title, updated email address, and LinkedIn profile URL.

Old and New, Side by Side

Findings are logged to a structured Google Sheet with the original contact details alongside the updated information: name, old email, old title, old company, current job, current email, and LinkedIn profile link. This side-by-side format makes it easy for the sales or PR team to review what changed and decide what to update in their CRM or outreach lists.

The sheet is a review queue, not an automatic overwrite. A person checks each row before anything changes in the CRM, so the team stays in control of what gets updated while skipping the slow part: the research. Our reference build is a Zapier Agent connected to email and Google Sheets, and the same workflow can be rebuilt as a Claude routine or as a HubSpot workflow, depending on where a team’s contacts and bounce notices already live.
