How to Set Up SMTP Providers in GoHighLevel

ClickUp users who also manage marketing automation often need reliable email delivery, and configuring SMTP correctly in GoHighLevel is a key part of that process. This step-by-step guide explains how to connect and manage SMTP providers in GoHighLevel so your outbound emails send securely and consistently.

This tutorial is based on the official GoHighLevel documentation and walks you through provider setup, configuration details, and essential testing and troubleshooting practices.

What Is SMTP in GoHighLevel?

SMTP (Simple Mail Transfer Protocol) is the standard method used by GoHighLevel to send emails from your account to your contacts. Instead of relying only on the platform’s native mail service, you can connect external SMTP providers for improved deliverability, control, and branding.

By integrating a dedicated SMTP provider with GoHighLevel, you can:

• Send emails from verified domains and custom addresses.
• Improve inbox placement and reduce spam issues.
• Monitor sending limits, logs, and bounces via your provider.
• Segment different types of email (marketing vs. transactional).

Before You Configure SMTP in GoHighLevel

Before you connect any SMTP provider to GoHighLevel, make sure you have the following information ready. You obtain these details from your email or SMTP provider’s dashboard.

• SMTP host address (for example, smtp.sendgrid.net, smtp.mailgun.org).
• SMTP port number (commonly 465, 587, or 25).
• Username and password for the SMTP service.
• From name and from email address you want to use in GoHighLevel.
• SSL or TLS encryption requirement (depending on the provider).

Also confirm your email domain is fully verified with the provider, including any DNS records such as SPF, DKIM, or tracking domains, according to your provider’s instructions.

Accessing SMTP Settings in GoHighLevel

All SMTP configuration happens inside the GoHighLevel settings area. Depending on your role and account structure, you can manage SMTP either at the agency level or the sub-account/location level.

1. Log in to your GoHighLevel account with appropriate permissions.
2. Navigate to the Settings section in the left-hand menu.
3. Locate the SMTP & Mail or similar email configuration option.
4. Open the SMTP settings screen to view existing connections and add new providers.

If you have multiple sub-accounts, repeat provider selection and default settings as needed for each one in GoHighLevel.

How to Add a New SMTP Provider in GoHighLevel

Once you are in the SMTP configuration area of GoHighLevel, follow these steps to add a new provider. Fields and labels may vary slightly depending on updates, but the overall process remains similar.

1. Click Add New SMTP

   Select the button or link to create a new SMTP configuration profile inside GoHighLevel.

2. Enter SMTP Provider Details

   Fill in the core connection fields supplied by your provider:

   • Provider Name – An internal label (e.g., “SendGrid Main” or “Mailgun EU”).
   • SMTP Host – The server address provided by your SMTP service.
   • SMTP Port – Typically 465, 587, or another port defined by your provider.
   • Username – The SMTP account or API user credential.
   • Password – The associated SMTP password or generated key.
   • Encryption – SSL or TLS, matching your provider’s recommendation.
3. Set From Name and From Email

   Choose the display name and email address that contacts will see as the sender. Ensure this address is verified with your SMTP provider before using it in GoHighLevel.

4. Select Default or Specific Use

   Some GoHighLevel setups allow you to set this SMTP provider as the default for the entire sub-account or limit it to specific pipelines or workflows. Configure this according to your email strategy.

5. Save the Configuration

   Click Save or Update to store the new SMTP configuration. GoHighLevel will validate basic fields and show a success message when the connection is stored.

Testing Your SMTP Connection in GoHighLevel

After you add an SMTP provider to GoHighLevel, testing is essential to confirm that your emails send correctly and are not blocked by authentication or connection issues.

1. Locate the Test Email Option

   In the SMTP configuration panel, find the option to send a test email.

2. Enter a Recipient Address

   Use an email inbox you can access quickly, preferably from a different domain than the one sending, to see how the email is received.

3. Send the Test Email

   Trigger the test from GoHighLevel and wait for it to arrive.

4. Check the Inbox and Spam Folder

   Verify the test email appears correctly:

   • Confirm the subject and body display as expected.
   • Check the “from” name and address are correct.
   • Look for any warnings about authentication or spoofing.

If the test email fails or does not arrive, review the connection details in GoHighLevel and compare them with the official settings from your SMTP provider.

Managing Multiple SMTP Providers in GoHighLevel

Many agencies and businesses working in GoHighLevel choose to configure multiple SMTP providers for different sending scenarios. This can help distribute volume, separate brands, or optimize deliverability.

Typical scenarios include:

• Marketing vs. transactional – Use one SMTP profile for campaigns and another for password resets or confirmations.
• Client-specific sending – Assign distinct SMTP providers for each client sub-account in GoHighLevel.
• Failover strategy – Maintain an alternative provider in case one service experiences downtime.

Within the GoHighLevel settings, you can edit each SMTP provider, change default status, or disable providers that are no longer in use.

Troubleshooting SMTP Issues in GoHighLevel

When SMTP is not working as expected in GoHighLevel, use the following checks before contacting support.

Verify SMTP Credentials in GoHighLevel

• Confirm the host, port, username, and password exactly match your provider’s documentation.
• Ensure no extra spaces or hidden characters were copied into the fields.
• Check that SSL/TLS settings match the provider’s requirements.

Check Domain and Authentication Status

• Verify SPF and DKIM records are properly added to your DNS for the sending domain.
• Confirm the sending domain and from address are verified in the SMTP provider’s dashboard.
• Look for any provider-side restrictions (like unverified sandbox mode or sending limits).

Review Logs with Your SMTP Provider

• Open your SMTP provider’s log or activity view.
• Search for recent messages sent from GoHighLevel.
• Review any errors or bounce codes to identify configuration issues.

If problems persist, compare your setup with the official documentation at the GoHighLevel SMTP setup article or reach out to your provider’s support team with the exact error messages.

Best Practices for Reliable SMTP in GoHighLevel

To keep your email sending stable and compliant, apply these best practices in GoHighLevel and with your SMTP provider:

• Regularly review bounce and complaint rates.
• Warm up new sending domains and IPs gradually.
• Keep contact lists clean by removing invalid or inactive addresses.
