@HighLevel should offer an email warm up service for new dedicated domains, like other email providers

I believe I was able to fix this for one of our sub-accounts by purchasing a dedicated IP for email sending. This might be the only reliable option, because when you're using a shared IP... alongside potentially thousands of other businesses, you have no control over the reputation of that IP. If other users are engaging in poor email practices or sending spam, it can negatively affect everyone sharing that IP, including legitimate businesses like ours.

By using a dedicated IP, you isolate your email reputation from other senders, which helps ensure better deliverability and protects your brand from being impacted by bad actors.

Additionally, when it comes to domain warm-up, there are serious limitations. It would be incredibly helpful if GHL offered:

More flexible and strategic use of multiple sending domains, and

A more intuitive way to cap daily email volume, especially during the warm-up phase.

Even if you set a drip to start small (say, 600 emails/day) as automations grow and contacts continue moving through actions over time, you can suddenly find yourself sending thousands of emails unintentionally. This overwhelms a cold or warming domain and can immediately damage its sender reputation.

These are major risks for agencies and businesses trying to scale responsibly. We'd appreciate any tools, settings, or visibility that would allow for better management of domain warm-up and sending volume.

2,5 years nothing has changed! Shame on you

Emails end up in spam all the time when sending to any Microsoft email account (outlook, hotmail etc)

Also Microsoft regularly blocks emails being sent, at least x2 a month I have to get in touch with support to adjust mailgun server/ip settings to remove the sending domain from whatever blacklist its on that time.

Any update?

The ability to warm up the sending domains might help.

Email isn't problem if you set it up right. Curious as to what GHL is going to do now that this is marketing "in progress".

I'Ive sent over 50,000 emails and have never had big isues with lanidng in spam or promotions unless it was my own fault due to key words in the subject. 9/10 the issue you guys are mentioning does not have to do with GHL. It';s your own end on how your creating the emails. Make sure your following best practices like using a name as the sender name (not a business name) and avoid spam / promotional key words in your subject lines.

I’ve found a couple of issues worth noting here:

We were on Sendgrid before switching to LC and their system, like GHL, allows us to set up multiple sending domains, but they check all our sending domains to match our sender to a verified domain and send from that domain. GHL should have this.

We have done some research and concluded that this is due to Microsoft Office 365 giving us SCL score of 5 when we set up a new email domain to send from.

Priya Jain can help you understand all the details around this and we're happy to help GHL by providing all the research we did around this so that you can understand the issue deeply.

In short, we used MailGun's Inbox Placement tool and found that deliverability is when we set up custom sending domains, for Microsoft Office 365, and the feedback from the Office 365 email service was that our SCL score was 5. Attaching screenshot.

We also tested using SendGrid, and found that and Microsoft's SCL was 1 (i.e. Not Spam).

It is impossible to know what triggers Microsoft to give it a spam rating, but we believe that it's due to the domain being new (since we have to set up new subdomains to send from GHL), and since Microsoft has never seen or been trained on that subdomain, they rate it as spam.

Here is Microsoft's explanation of what their SCLs mean: https://learn.microsoft.com/en-us/microsoft-365/security/office-365-security/anti-spam-spam-confidence-level-scl-about?view=o365-worldwide

There is an easy way around this, and that is to give us the , because then we can send emails without the need to set up new subdomains first.

This is something Mailgun supports natively, please see this article: https://help.mailgun.com/hc/en-us/articles/203357040-Can-I-Use-the-Same-Domain-Name-for-Mailgun-and-for-Google-Apps-Or-Another-Email-Server-

The problem today is that in GHL, , which prevents us from using LeadConnector in the way described above. If you allowed this, the issue is most likely resolved :)
