Email sending is suspended when HubSpot's deliverability protection system detects a high bounce rate on your email recipients, or fraudulent account activity is detected. All marketing emails and automated emails in workflows are not sent while marketing email is suspended.
Before marketing email sending is suspended, you may see a warning banner in your email tool about a problem detected by the deliverability protection system. The banners contain more details about the problem, and recommendations to improve future emails.
Please note: you can reach out to marketing email experts for advice on improving your emails on the Email Deliverability topic board on the Community.
What is a suspension?
There are two types of email suspensions:
- The deliverability protection system detects excessive hard bounces, unsubscribes, spam reports, blocklisting, or abuse complaints. Learn more about what to do about this type of suspension.
- The system detects fraudulent activity on your account, such as spam traps. Learn how to respond to this type of suspension.
What are the email limits?
- Hard bounces: HubSpot's hard bounce limit is 5%. For reference, many ISPs prefer bounce rates to be under 2%.
- Spam reports: HubSpot's spam complaint rate limit is 0.1% (1 in 1,000 messages sent). Spam reports are when a recipient clicks the spam button while viewing your email in their inbox, or drags the email into their junk folder.
- Direct complaints: if any direct complaints are sent to HubSpot's abuse desk, marketing email sending in your account may be suspended.
- Unsubscribes: HubSpot's unsubscribe rate limit is 5%. A healthy unsubscribe rate is less than 2%.
What should I do if email sending is suspended?
Free CRM accounts
You'll be notified about the suspension in a banner message in your email tool. After email sending is suspended, the email tool will remain locked. With a free CRM account, you cannot appeal the suspension.
You can continue to use the other tools in your HubSpot account.
Marketing Hub Starter accounts, Sales Hub Starter, Professional, and Enterprise accounts, Service Hub Starter, Professional and Enterprise accounts, and free trial accounts
To appeal your email suspension:
- In your HubSpot account, navigate to Marketing > Email.
- Click Submit appeal in the banner at the top of the page
- In the dialog box, fill out the appeal form:
- Confirm that you imported an opt-out list and cleaned up your contact lists.
- Specify where you obtained your contacts, confirm you've emailed them in the last year, and provide additional information on how the contacts provided their email addresses.
- Click Create ticket to submit your appeal.
- After you submit your appeal, a HubSpot support specialist will contact you to gather more information if necessary, and the Email Deliverability Team will make a final decision whether to restore email access.
Please note: HubSpot will automatically suppress any contact that has already hard bounced, unsubscribed, or marked an email as spam. Removing these contacts alone is not sufficient to restore email access.
