GoHighLevel Email Domain Warm-Up: How It Works and How to Turn It On

Short answer: GoHighLevel now has automated email domain warm-up for dedicated sending domains. Once your account is approved for the beta, a Start warm-up button appears on the domain card under Email Services, Dedicated Domain and IP. You pick a daily goal, HighLevel creates warm-up mailboxes on your domain and slowly raises volume with conversation style emails, and you watch a 0 to 100 health score. HighLevel says it is free for approved beta users and that pricing after the beta has not been announced (Official). It was listed in the LevelUp Day 2026 roundup.

What email domain warm-up does

A brand new sending domain has no reputation. If it suddenly sends thousands of emails, Gmail, Outlook and Yahoo are more likely to send them to spam, bounce them or block them. Warm-up builds trust slowly before your real volume arrives.

According to HighLevel's help article (Official), the platform does this for you with dedicated warm-up mailboxes on your domain that:

• Ramp daily volume step by step toward the goal you choose.
• Exchange conversation style emails, including threaded replies.
• Mark warm-up emails as important.
• Pull warm-up emails out of spam when they land there, shown as "Saved from spam".
• Keep engaging over time to hold the reputation.

These mailboxes are created and managed by HighLevel. Your contacts never receive warm-up emails, and campaigns and workflows can keep sending during warm-up within the usual sending limits.

Who can use it and what it costs

• Status: beta. You request access through the form linked in HighLevel's help article. Once approved, the Start warm-up option appears.
• Who: agencies and sub-accounts, but only on dedicated sending domains. It does not apply to the shared default domain.
• Cost: "currently free for approved beta users" (Official). Pricing after the beta has not been announced yet.
• Requirements: the domain must be verified and its SSL certificate issued before you start.
• Existing domains: you turn warm-up on manually. HighLevel then looks at past sending and, if connected, Google Postmaster Tools data to plan the ramp.

One detail matters for busy senders: turning on warm-up removes the daily sending limit ramp currently shown on the dedicated domain, so warm-up takes over that job.

How to set it up

1. Go to Agency Settings or Sub-Account Settings, then Email Services, SMTP Service, and open the Dedicated Domain and IP tab.
2. Check that the domain shows as verified with an issued SSL certificate. If not, fix DNS first.
3. Under Domain Warm-Up on the domain card, click Start warm-up.
4. Under Daily goal, click Change and choose a limit. HighLevel's examples are 10,000 and 25,000 emails a day.
5. Review the mailbox count. In HighLevel's example, a 25,000 a day goal uses 5 mailboxes capped at 5,000 a day each.
6. Click Start warm-up. The badge changes to Warming up.
7. Optional but recommended: connect Google Postmaster Tools for spam rate, authentication and delivery error data.

If you manage several brands, set up warm-up on each dedicated domain separately; each domain card has its own goal, mailboxes and report, so a problem on one brand does not hide inside another.

Results can take one to two days to show. Zero sends or zero deliverability in the first day is not necessarily a problem.

Reading the health score and report

The domain card shows a health score from 0 to 100 based on deliverability, sender reputation and DNS setup, the deliverability rate of warm-up emails, and sent today against your goal. Click View report for:

• DNS records for SPF, DKIM, DMARC and MX. Green is configured, red is missing or invalid. Fix red records with your DNS provider first; nothing else helps as much.
• A Landed in inbox chart comparing inbox placement with saved from spam.
• A list of warm-up mailboxes with status and daily caps. For now, only the sender name can be edited.

You can pause or stop warm-up from the three dot menu on the domain card. HighLevel warns that stopping early slows reputation building, especially on new domains.

What to do now

• Pick a realistic goal. The daily goal is a ceiling, not a promise. Choose what you will actually send, not the biggest number.
• Do not skip list hygiene. Warm-up builds reputation; sending to old, unengaged or bought lists burns it again. Clean the list before a big send.
• Check authentication first. If you are not sure your domain is set up right, read how to check if your GoHighLevel sending domain is broken.
• Track results. Compare inbox placement with real campaign numbers; see getting real SMS and email reports out of GoHighLevel.
• Agencies: request beta access for client domains that are new or about to scale, and add warm-up to your onboarding checklist.

HighLevel does not promise specific inbox rates, and neither do we. Warm-up is one part of deliverability next to clean DNS, good lists and content people want.
