GoHighLevel Email Not Sending — 8 Fixes That Actually Work

Before You Debug: Check the Basics

When emails stop sending in GoHighLevel, the temptation is to dive straight into complex troubleshooting. Start with the basics first — in most cases, one of these eight issues is the cause.

Fix 1: Your Sending Domain Is Not Verified

GoHighLevel requires a verified sending domain to send emails. Go to Settings → Email Services → Sending Domains. If your domain shows as "Pending" or "Unverified", your emails will not send. Complete the DNS verification process — add the CNAME and TXT records GoHighLevel provides to your domain registrar.

Fix 2: You Have Hit Your Sending Limit

New domains on LC Email have daily sending limits that increase over time as you build sender reputation. New domains typically start at 50 to 100 emails per day. If you have exceeded your limit, emails queue until the next day. Check Settings → Email Services for your current limits.

Fix 3: The Workflow Trigger Is Not Firing

If emails are not sending from a workflow, the issue may be the trigger rather than the email action itself. Check your workflow history to see if the workflow is actually running. If there are no recent executions, the trigger condition is not being met.

Fix 4: The Workflow Is in Draft Mode

A workflow set to "Draft" does not run. Open your workflow and check the toggle in the top right corner. It must say "Published" for any actions to execute.

Fix 5: SMTP Configuration Error

If you are using a third-party SMTP provider (SendGrid, Mailgun, Google Workspace), verify the connection. Go to Settings → Email Services and test the SMTP connection. A failed connection test means credentials need updating.

Fix 6: Contact Has Unsubscribed

If a specific contact is not receiving emails, check their contact record. If they have opted out or been marked as "Do Not Email", GoHighLevel will not send them any emails. This is intentional and correct — you cannot override DNC status.

Fix 7: Email Content Triggering Spam Filters

Some email content is blocked before it even sends. Avoid using URLs that have been previously flagged as spam, excessive HTML formatting, and certain trigger phrases. Send a test to yourself first to verify delivery.

Fix 8: The Email Action Has No From Address

Check the specific email action in your workflow. If the "From" name and email field is empty or set to a domain that does not match your sending domain, the email will fail to send.
