HubSpot Marketing uses a range of 32 IP addresses to send notifications for new form submissions, CSV file exports, and the like. There are also a few other IP addresses used by HubSpot for specific features in the Marketing and Sales platforms.

To ensure delivery of these emails to your inbox (and the inboxes of your team members) please ask your IT team to whitelist the following IP addresses:

  • - or the range - notification emails for new form submissions, CSV file exports, etc. 
  • - emails from the Send a Test Email feature in the Email tool
  • - emails from the HubSpot CRM 
  • - emails from HubSpot Marketing Free

The IP addresses above are not used for Marketing emails sent by our customers. These emails use a different set of IP addresses. Please contact HubSpot Support if you don't know the sending IP address for your HubSpot Marketing account.
