Hi @Local-Prod,
I was able to check out your account and found that two of the most recent email campaigns had hard bounce rates of 18.25% and 18.60% respectively. These rates greatly exceed HubSpot’s acceptable email limits, which resulted in automatic Deliverability Protection actions.
Email suspensions due to exceeding HubSpot’s acceptable thresholds in HubSpot Marketing Free accounts are not eligible for remediation. Email sending will remain locked moving forward, however, you may continue to use other tools available on the HubSpot platform. This includes 1:1 email sends through the CRM and your connected inbox. Check out this guide for more on what you can do with a connected inbox.
