Outgoing emails from google group are going straight to spam

Hi Folks,

I have set up inbox with google groups(with other mail account and than google groups). Almost everything works well so far, but there is a big problem.

All outgoing emails are send via bf.hubspot-inbox.com and land in the spam folder.

I use in the from address settings Customize from address. This custom email is the main email of the google group.

How can I sent emails direct with this custom gmail address instead of via bf.hubspot-inbox.com?

Mail will always be sent with that via unless you have setup domain authentication via DKIM/SPF records in your DNS. Being that you are on a free account, you may not have access to these options and would need to upgrade to a paid plan to help with the email deliverability.
