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, blacklisting, 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: you'll see a warning in your account if your unsubscribe rate limit is over 5%.
