How to Use SMTP Credentials for LC Email Dedicated Domains in GoHighLevel
By Marnix Geerkens. Published 2024-04-30. Updated 2026-06-02.
GoHighLevel's LC Email dedicated domains now support SMTP credentials, letting you connect the domain to external email warm-up services. You create an SMTP user under the domain's settings, generate a password, and use those credentials to authenticate with the external service. You can also set up individual addresses for each team member, and any email sent directly to those addresses lands in the Conversations tab.

Summary. SMTP credentials for LC Email dedicated domains allow GoHighLevel sub-accounts to integrate with third-party warm-up tools, which is important for new domains trying to build sender reputation before sending at volume. You navigate to Settings > Email Service > Dedicated Domain and IP, open the SMTP settings for your domain, create one or more SMTP users with passwords, and connect those credentials to the warm-up service of your choice. A secondary benefit is that inbound emails sent to the SMTP addresses appear directly in GoHighLevel Conversations.

Frequently asked questions

New sending domains need established reputation before high-volume sends to avoid spam filters.

Where do inbound emails sent to the SMTP addresses appear in GoHighLevel?
They land directly in the Conversations tab without requiring a prior outbound email.
