We have a problem when sending emails to "gmail.com" domain. All of our emails end up in spam folder.
We do not send spam or bulk emails, so I would like to know is there a way to solve this issue.
I have browsed some topics and it appears we are not blacklisted, but the problem is in spam filtering.
Really don't know what do do next
There is no real solution. The best things you can do for now is to enable both SPF and DKIM for your domain/mail server, but google's filter is still pretty strict.
