Newsletters going to the spam folder. Which paid version is required to improve deliverability?
SOLVE
My company started a newsletter. However we realized most of the email were going to the recipients' spam folder. From the hubspost comunity, I understood that the issue is that we need to update our SPF record with the entry for the Hubspot servers. But in order to obtain Hubspot servers informations, a paid version of Hubspot marketing is required. (If you have any other simpler advice, please don't hesitate to give it to me please!)
I need to know whether Hubspot technical information is shown with the Starter version or the "higher", more advanced versions are required.
