IP Information for Whitelisting

We use HubSpot to deliver our email communications, and their mail server info is provided below. Any outgoing message sent from HubSpot will be generated by one of these servers, so if you configure your filters to allow this mail, all messages should be received, regardless of the email address used. HubSpot may periodically add or remove IPs within this larger range, but is unlikely to go outside it in the foreseeable future.
