Default Email Headers in GoHighLevel for Dedicated Sending Domains
If you are used to tools like ClickUp for managing workflows, understanding how email headers work in GoHighLevel will help you better organize and optimize your outbound campaigns. This guide explains which default email headers are applied when you use a dedicated sending domain and what they mean for deliverability, tracking, and compliance.
By the end of this article, you will know exactly how GoHighLevel structures your outbound email headers and why these defaults are important for performance and inbox placement.
What Are Default Email Headers in GoHighLevel?
Every email sent through GoHighLevel includes technical information in the header. These headers are not usually visible to your contacts, but email providers, spam filters, and analytics systems rely on them for routing, authentication, and tracking.
When you configure a dedicated sending domain, GoHighLevel automatically adds a set of default headers to your messages. These headers ensure that emails are sent from the correct domain, validated by authentication records, and measured accurately for engagement.
Why GoHighLevel Default Headers Matter
The default headers used by GoHighLevel are essential for:
- Improving email deliverability and inbox placement
- Maintaining consistent branding and from-address formatting
- Supporting unsubscribe and compliance requirements
- Enabling accurate open, click, and bounce tracking
Understanding these headers helps you troubleshoot deliverability issues and verify that your dedicated sending domain is working as intended.
How GoHighLevel Handles Dedicated Sending Domains
When you set up a dedicated sending domain, GoHighLevel uses that domain in the visible From address and aligns your technical headers with the domain configuration. This typically involves DNS records such as SPF, DKIM, and sometimes DMARC, which work together with the email headers.
With a dedicated domain, GoHighLevel focuses on:
- Using your chosen domain in the display and envelope sender
- Ensuring authentication passes where records are set correctly
- Maintaining a consistent identity across campaigns
These settings help mailbox providers recognize your mail as legitimate and reduce the chance of landing in spam folders.
Key Default Headers Used by GoHighLevel
Below is an overview of the main categories of default headers that GoHighLevel applies when you send from a dedicated sending domain. The exact values are system-generated, but their functions remain consistent.
GoHighLevel From and Sender Headers
GoHighLevel sets headers that control who the email appears to be from and how the email is routed behind the scenes:
- From: The display name and email address your contact sees in their inbox. This uses your dedicated sending domain.
- Sender / Return-Path: The technical return address used for bounces and processing. It often uses a subdomain or specialized address aligned to your sending setup.
These headers help mailbox providers verify that the visible sender matches the authenticated domain and maintain a clear identity for your brand.
GoHighLevel Authentication Headers
Authentication headers are critical for proving that GoHighLevel is allowed to send on behalf of your domain:
- SPF alignment (via the Return-Path domain and your SPF record)
- DKIM signature that cryptographically signs the message content
- Support for DMARC alignment when your DNS policy is configured
When properly configured, these headers tell receiving servers that the email is authorized and has not been tampered with in transit.
GoHighLevel Tracking and Analytics Headers
GoHighLevel also adds headers related to tracking and analytics. These allow the platform to attribute events like opens, clicks, and bounces to the correct contact and campaign:
- Unique campaign or message identifiers embedded in headers
- Internal routing values that let the system log metrics for each email
- References that support threaded conversations for replies in some clients
These tracking headers do not affect how the email looks to your contact but are vital for reliable reporting.
GoHighLevel Compliance and Unsubscribe Headers
To support industry standards and legal requirements, GoHighLevel includes headers that help with compliance and unsubscribe handling:
- List-Unsubscribe: Provides a direct link or email method for unsubscribing
- Optional indicators that the message is part of a marketing or list campaign
- Values that align with your account-level mailing settings
Mailbox providers can use these headers to show an unsubscribe option directly in the inbox interface, improving user experience and reducing spam complaints.
Step-by-Step: Verifying GoHighLevel Default Headers
If you want to see the actual default headers used by GoHighLevel for your dedicated sending domain, you can verify them with a simple process.
1. Send a Test Email from GoHighLevel
- Create a basic email campaign or use a test email feature.
- Select the dedicated sending domain you have configured.
- Send the test email to a mailbox you control (for example, Gmail or Outlook).
2. Open the Full Email Headers
In the receiving inbox:
- Open the test email.
- Locate the option to view Full headers or Show original.
- This reveals the raw header information applied by GoHighLevel and the receiving server.
3. Review Key Header Fields
In the full header view, confirm:
- The From address uses your dedicated domain.
- The Return-Path or Sender address is aligned with the GoHighLevel sending infrastructure.
- Authentication results show SPF and DKIM passing when your DNS is correctly configured.
- The presence of List-Unsubscribe and other list-related headers.
Comparing these details with your DNS configuration helps you confirm that your dedicated sending domain is active and working as intended.
