What causes GoHighLevel to suspend email sending?

According to HighLevel's help article on email bounce suspension, the system suspends sending when a sub-account's bounce rate reaches about 5%. Bounces happen when messages go to addresses that are invalid or no longer accept mail. Agency admins get a warning at about 3%, before the suspension threshold.

How long does a GoHighLevel email suspension last?

The help article (updated September 17, 2026) says the first and second blocks last 12 hours. A third block is permanent and requires HighLevel Support to lift. HighLevel has also published a changelog describing a separate progressive schedule for ESP-block monitoring, with a 24-hour step, so check the notice in your account for the current terms.

How do I get email sending back on a suspended sub-account?

Run your contacts through the Email Verification Service to remove invalid addresses, pause bulk sends and cold email campaigns, then wait out a temporary block. The help article says enabling verification can let you resume sooner. For a permanent block, contact Support with your sub-account ID and an error screenshot.

Will email sending be suspended if I email people who did not opt in?

Sending to people who never agreed to hear from you tends to produce bounces and complaints, which are what push a sub-account over the threshold. Limiting sends to opted-in contacts and removing invalid addresses before a campaign are the practical protections.

How do I stop email suspensions from happening again?

Verify a list before any bulk send, watch the bounce rate in your reports, and remove addresses that bounce. Keep SPF, DKIM and DMARC set up correctly, since authentication affects whether mail is delivered. Our guide on email deliverability covers the DNS records.

Key takeaways

HighLevel's help article says email sending is suspended when a sub-account's bounce rate reaches about 5%, after an earlier warning at 3% that goes to agency admins.
The first and second suspensions last 12 hours. A third suspension is permanent and needs HighLevel Support to review.
The fastest way to resume is to clean the contact list with the Email Verification Service and pause bulk and cold campaigns while you do it.
HighLevel's changelog describes a different, progressive schedule for ESP-block monitoring, so check the current notice in your account rather than relying on any one number.

A suspension on a GoHighLevel sub-account usually means its bounce rate went over the limit: too many emails went to addresses that were invalid or no longer accepted mail. The suspension is a protection for sender reputation, not a penalty you can argue away. Clearing the bounce problem and using the Email Verification Service are how you get sending back. HighLevel’s official article on bounce suspension is the reference for the current rules.

What triggers it

HighLevel’s help article on email bounce suspension says the system watches each sub-account continuously. Agency admins get a warning at about a 3% bounce rate. Sending is suspended when the rate reaches about 5%. The sub-account’s own email address also receives an alert when the suspension starts.

How long it lasts

The article, updated September 17, 2026, describes the first and second blocks as 12 hours each, and a third block as permanent. A permanent block needs HighLevel Support to review it. HighLevel’s changelog also describes a progressive enforcement schedule for ESP blocks, with a 24-hour step. Because these thresholds change, read the notice in your account for the terms that apply to you.

How to get sending back

Verify the list. Run the contacts through the Email Verification Service and remove the invalid addresses. The article says enabling verification can let you resume sooner.
Pause sends. Stop bulk sends and cold email campaigns until the list is clean.
Wait or contact Support. For a temporary block, wait out the 12 hours. For a permanent block, contact HighLevel Support with your sub-account ID and a screenshot of the error.

How to avoid another one

Verify a list before any bulk send, not after the bounces arrive. Watch the bounce rate in your reports and treat a rising trend as a warning. Send only to people who opted in or who expect to hear from you. Set up SPF, DKIM and DMARC correctly so mail that is legitimate is less likely to be filtered, and remove addresses that bounce so they don’t come back in the next campaign.

If a sub-account keeps getting suspended after you have cleaned the list, the problem is usually the source of the addresses, not the sending schedule. That is a conversation to have with HighLevel Support or with whoever built the lead capture.
