First of all, WebMail is for internal use. Not for external mailing. In the case of external mailing, we see many problems in your mail delivery failed or not received at the time of receipt. In a word, webmail is for general use and for internal use. To use it professionally, you must use Business Mail or Mail Exchanger. For free, there are Zoho, Yandex and many paid ones like GSuite, Microsoft Office 365, Zoho Pro etc.

Now why WebMail spam goes,

1. Your domain is brand new which the mail companies do not trust, so they keep it in spam, this may happen in the case of paid mail service for some time.
2. You are using web hosting, not mail hosting, mail companies recognize this server as a web hosting server.
3. No unsubscribe header.
4. There is a file or text that goes to spam according to the algorithm of the mail company.
