How to Enable Initial Email Verification in GoHighLevel
Keeping your email lists clean is crucial for high deliverability and avoiding spam folders. GoHighLevel integrates with Mailgun to provide robust email verification, checking contact emails as they enter your system. This ensures that only valid email addresses are added, saving you from sending to non-existent or problematic contacts and protecting your sender reputation. Follow these steps to activate this essential feature at the agency level.
✅ Email verification is a paid service, charged at $0.012 per email verified. This cost applies each time an email is checked by the system.
Before enabling for all sub-accounts, consider running a quick test on one sub-account to understand the cost implications based on your contact inflow. You can track usage in your Mailgun account.
How to Set Up Email Re-Verification for Ongoing Cleanliness
While initial verification is vital, email addresses can become invalid over time. People change jobs, abandon old accounts, or mark emails as spam. GoHighLevel offers a re-verification feature that automatically re-checks emails every 90 days, ensuring your contact lists remain fresh and highly deliverable. This proactive approach helps maintain a strong sender reputation and reduces bounce rates for your ongoing campaigns.
Regular re-verification is especially useful for long-term nurture sequences or large lists that aren't frequently updated. It prevents you from wasting marketing efforts on dead email addresses.

Understanding Email Verification Status in Contact Records
After enabling email verification, you can easily check the status of any contact's email address directly within their contact record. This visual cue provides immediate insight into the deliverability potential of an email, allowing you to make informed decisions about your communication strategies. Knowing the status helps you identify problematic contacts and refine your outreach efforts.
If an email shows a red status due to a bounce, consider reaching out to the contact through an alternative method (like SMS or phone) to update their email address. Do not continue sending emails to bounced addresses, as it harms your sender reputation.
