Mail-tester.com giving me 10/10 but still in spam

Hi guys, I am quite new to mail server. I set up a new domain and new VPS and followed the guide https://www.linuxbabe.com/mail-server/debian-9-stretch-iredmail-email-server. After completing everything i managed to send a test mail to mail–tester and got a 10/10 score. Still i end up in the spam folder. What should i do now?

New mail servers often don’t have a good reputation. You need to improve your IP reputation and domain reputation. Please read the following article for how to do it.

So we continue with Mailjet.
