Your marketing email may be stopped automatically by HubSpot's email protection system. The system will stop emails if the email starts to accumulate a high percentage of hard bounces, spam reports, or unsubscribes from your recipients. These events can hurt your email sending reputation and cause your emails to go straight to spam. Learn more about improving the deliverability of your emails.
To protect your sending reputation, complete the following steps before trying to resend your email:
When you receive the notification from HubSpot about your stopped email, click Send to remaining engaged contacts to send a clone of your original email to any remaining recipients who have received, opened, or clicked one of your emails, or opted in through a form submission.
Clicking the Send to remaining engaged contacts button will bring you directly into the email editor of a clone of your original email that was stopped. This email clone will contain a new exclusion list in the recipients section to ensure that any unengaged contacts are dropped automatically when you re-send the message.
Please note: if no contacts match the engagement criteria outlined above, the Send to remaining engaged contacts button won't be displayed in the email notification from HubSpot.
