Email Bounceback Detection

Updated over 2 weeks ago

Email Bounceback Detection is a feature that automatically identifies when an engaged person’s email bounces back. When a bounce is detected, the contact’s email is marked as “inactive” in CRM via a custom field, ensuring that customers have the most up-to-date information on whether a critical contact has left the company.


Email bouncebacks can inform you that a contact may have left a company. By automatically marking these emails as inactive, you can better manage your sales outreach, maintain a clean CRM, and improve your forecasting accuracy. This helps sales teams focus on active, engaged contacts, ultimately driving more successful outcomes.


This feature is available for all customers using the Forensics, Forecasting, Premium/Enterprise Opportunity Management, and Premium/Enterprise Account Management plans.

How can I use it?

To utilize this feature, the customer must create a Salesforce field with the same name as the People.ai field and provide permission via the People.ai integration for People.ai to manage this field.


Upon enabling the feature, People.ai will retrospectively store the email status for contacts based on the most recent activity during the customer’s tenure, but only update the CRM if new activity is observed.

How does it work?

  1. Detection: Our model scans the content of the email for any language that explicitly suggests delivery failure, and cross-references this with the sender’s email domain and any available API header metadata.

  2. Verification: Once detected, the feature confirms that no outbound activity from the contact has occurred after the bounce to ensure that automated replies or temporary issues, like out-of-office emails, are not mistakenly flagged.

  3. Update Cycle: Once the bounceback has been confirmed, the system updates the email_active field in CRM daily for contacts with no new data from the CRM or any activities in the past seven days.
