ISSUE SUMMARY:
All emails sent from my site is marked as spam, so people miss them
the site is not even started yet and only 2 accounts on it to test and fix so it will be good when releasing site.
so it cant be that people reported emails as spam.

i use mail() as email sender in settings
from info@ adress and "from" is Mysitename.com.

HI, Daniel.

Marking as spam depends from user anti-spam filter restrictions. Some users will receive them without issues, other will need to check spam box. Emails are sent as html so they are always treated suspicious than text emails.

So what you can do?

Send emails as text... or:

- test your email address here: www.mail-tester.com/
- then add SPF record to your domain
- sign your domain with DKIM keys
- check if your email IP is on black lists and try to remove it
- check if you use SMTP or rather PHPmailer (SMTP is recommended)
- check if you use static or dynamic IP address for emails (if you use dynamic... then adding SPF will be in vain).
