All mail goes to spam

[apinto]

Make sure your ip is not blacklisted or with bad reputation.

Checking Senderbase (https://www.senderbase.org/lookup/?searc...38.182.138) does not look bad at all.

Are you sending to Gmail?
What is the reason gmail tells you for it going to spam? (please refer to: http://www.whatcounts.com/2012/03/gmail-...marketers/)

Does it only happens on Gmail?
One tool I found usefull is https://www.mail-tester.com/ , do a test and post back here the results url so we can check it better.

Try DKIM... might help...

Sometimes Gmail and Hotmail mark some IP ranges for unknown reasons (most related to previous owners spam reputation), when this happens there is little you can do, however I know of reports that sending email to multiple gmail address and marking the emails as "Not Spam" does help bringing your reputation back up (do this carefully or you might end up in a worse situation).
