A family of member of mine reached out about their family owned company emails often going to receivers spam, which is hurting their business.
I haven't found out much about their setup (ie who hosts emails), but I did ask her to send me a test email.
My guess is that it's a reputation thing, since they are probably using some local ISP to host their emails and website. I'm not an email expert though.
I inspected the email and see the line:
Received: from outgoing11.cpt4.host-h.net (outgoing11.cpt4.host-h.net. [197.189.123.123]) [redacted the IP, since it may be their public IP]
Using ipqualityscore.com I checked that IP and I get:

I think my assumption is correct that it's their email service provider? I almost want to try convince them to switch over to Google Workspaces for ease of use. At least then you don't have these types of issues.
