Why your GoHighLevel emails go to spam (and how to fix it)

HighLevel generates the exact values, so copy and paste them and don't edit anything. In the Name or Host field, enter only the subdomain part (for mail.yourbrand.com that's "mail"), use "@" only for a root domain, and set TTL to 300 seconds if your host lets you.

The mistakes that break verification are almost always the same: a second SPF record (merge them into one), a second DMARC record, an old Mailgun or HighLevel MX or SPF record still on the subdomain (that's the "Domain already pointing to email server!" error), a wildcard record that makes the subdomain look taken, and Cloudflare proxying. In Cloudflare every one of these records has to be set to DNS only, the gray cloud.

This is the most common complaint in the GoHighLevel groups: everything passes, Postmaster says compliant, the domain isn't blacklisted, and simple appointment reminders still land in spam. Authentication only proves the email is really from you. It says nothing about whether people want it. Once the records pass, inbox placement comes down to reputation, which is built from complaints, bounces, engagement and how steadily you send.

Check these next. Is the domain inside its first 4 weeks? Did you blast a big, old list on day one? Is the From address on the same domain as the sending domain? Are you sending to yourself on the same domain (info@ to susan@ at the same company looks like spoofing, so test with a Gmail address)? Are there link shorteners like bit.ly in the email? HighLevel calls those out as a spam signal.

The "via mailgun.org" or "sent via msgsndr.com" line in Gmail means the DKIM signature is for a different domain than your From address. A verified dedicated domain with an aligned From address removes it.

If a domain is already warmed up and still goes to spam, HighLevel's own advice is to set up a fresh subdomain. Repairing a damaged one is slower.

Google calls you a bulk sender once you send close to 5,000 messages in 24 hours to personal Gmail accounts, counting everything from the same primary domain, so mail.yourbrand.com and promo.yourbrand.com add up together. Once you hit it, the status is permanent. Google's FAQ says that starting November 2025 Gmail is ramping up enforcement, and non-compliant mail now gets temporary and permanent rejections. Yahoo's rules are almost the same.

These rules apply to mail going to personal Gmail and Yahoo inboxes. Google says they don't apply to mail going to Google Workspace business accounts, but those have their own filters, so set everything up anyway.

Mostly. HighLevel adds the one-click List-Unsubscribe header to every email except 1-to-1 emails. You still need a visible unsubscribe link in the body, so add the Footer element in the email builder with the default LC Email unsubscribe link or a custom one. Leave it out and you're breaking both Gmail's and Yahoo's rules, and people hit the spam button instead.

Inbox providers don't trust a brand-new domain, because anyone can register one. HighLevel says a domain can take up to 4 weeks to warm up, and Google says to raise volume slowly, send at a steady rate and avoid sudden spikes.

Option 1 is the fixed-stage ramp. Every new dedicated domain is enrolled when it's verified. Stage 1 is 1,000 emails a day, and you only move up a stage on a day you actually hit the full limit, all the way to stage 15 at 250,000 a day. Missed days pause progress but don't reset it. Send every day, send to opted-in contacts first, and drip big sends with Bulk Actions or a workflow.

Option 2 is the new Domain Warm-Up beta (released Oct 27, 2026). You request access with HighLevel's form, then go to Settings > Email Services > SMTP Service > Dedicated Domain and IP and click Start warm-up on the domain card. Pick a daily goal like 10,000 or 25,000 (that's a ceiling). HighLevel creates its own warm-up mailboxes on your domain that send threaded conversations, reply, mark emails important and pull them out of spam. Your contacts never get these. The report shows a 0 to 100 health score, inbox placement and your DNS status, and data takes a day or two to show up. It's free during the beta, and HighLevel hasn't announced pricing after that.

Two things to know about the beta: the domain needs a verified status and an issued SSL certificate before the button appears, and turning it on removes the daily sending limit ramp on that domain. You can pause or stop it from the three-dot menu on the domain card.

The fastest way to get a sub-account's email shut off is importing an old list and blasting it. HighLevel watches the bounce rate continuously. 0 to 3% is healthy. At 3% you get a warning, at 5% sending is suspended for 12 hours, a second strike is another 12 hours, and a third is permanent until Support manually reviews the account. Only email stops. SMS, calls and workflows keep running.

Since August 13, 2026 the lock waits for a bigger sample before it fires (at least 25 bounces, with a send floor of up to 500), so a small sub-account won't get locked over three bad addresses anymore. A bad list still gets caught.

Before you import anything, verify it. Suppress anyone who hasn't opened or clicked in 90 days, remove hard bounces right away, filter role addresses like info@ and admin@, and never import a list you didn't collect yourself. On forms, use double opt-in or reCAPTCHA so bots can't fill your list with junk.

Promotions isn't spam. It's Gmail sorting mail it thinks is marketing, and your email still gets delivered. People in the HighLevel groups report the same message landing in Primary when they send it straight from Gmail and in Promotions when it goes out as a campaign, most likely because a campaign carries the signs of bulk mail, like a designed template, tracked links and an unsubscribe header.

If a message is really 1-to-1, like a reply to a lead, send it from Conversations through the Gmail or Outlook sync. For campaigns, plainer emails with fewer images and links read more like a real message. Don't fight Promotions with tricks like fake "Re:" subject lines. Google's guidelines name those as deceptive, and they lead to complaints.

LC Email is the built-in sender that every sub-account gets, billed per email from the agency wallet (rates in Usage fees). Every email counts, inbound and outbound, To, CC and BCC. You can see usage under Agency View > Billing > Credits, and on the $297 and $497 plans you can rebill it to clients (with a markup only on $497). The full plan breakdown is on Pricing.

New agencies start on LC Email, and it's the only option where HighLevel builds the dedicated domain, warm-up and verification in, and where Support will dig into deliverability. You can still connect your own provider under Settings > Email Services. HighLevel uses the sub-account's default provider first, then the agency's.

Your own Mailgun account makes sense if you already run your sending there or want Mailgun's dedicated IP pools. Use a subdomain like mg.yourbrand.com. With one shared Mailgun subdomain for every client, one bad list takes email down for all of them, so give each client their own. Mailgun's pricing page today: Basic from $15 a month for 10,000 emails, Foundation $35 a month for 50,000 (first month free), Scale $90 a month for 100,000.

Gmail or Outlook: for a salesperson's 1-to-1 email, use HighLevel's two-way Gmail or Outlook sync, not SMTP. Don't use a Workspace mailbox to send campaigns. HighLevel says Gmail allows roughly 100 to 150 emails a day through a remote client, and over SMTP HighLevel only gets sent, open, click and bounce events, so an email only shows as delivered once someone opens it.

Cold email: HighLevel's own advice is not to do it on your main sending domain. If a client insists, use a separate sub-account and a separate domain, verify every address and drip slowly, or use a dedicated cold email tool and bring people into HighLevel once they reply. Check the law where you and the recipients are. This isn't legal advice.

Work through these from cheapest to deepest. One warning on stats: open and click rates are a weak signal. Apple's privacy features and corporate security scanners open and click emails automatically, and one team in r/HighLevel found most of their campaign opens and clicks were bots even with filtering on. Replies, bookings and Postmaster's spam rate are better scores.

Give every sub-account its own dedicated subdomain on the client's own domain. HighLevel says not to share a sending domain across sub-accounts. A sub-account without its own dedicated domain is treated as shared, even if the agency has one. Put it on your onboarding checklist next to the phone number and A2P, and ask for DNS access early, since you can't publish the records without it.

If you're white-labelling, a branded subdomain also stops your clients' customers from seeing HighLevel's sending domain in their inbox, so do it when you set the account up. White label guide covers the rest of the branding.
