Many of us who use e-mail on a shared host go to spam, there are many reasons to go to this spam, it is better not to use this e-mail professionally for general use of e-mail on a shared host because many clients use e-mail from the same server, many clients are intentional. Or unintentionally abuses email, which leads to bad IP reputation, and many clients send email at the same time, causing email to be sent late. Or, the main thing is that the email on the shared host is not set up to use the email in a dedicated way, for this, for professional use, you must use a business mail or mail exchange such as the free Zoho, Yandex and many paid ones such as: GSuite, Microsoft Office 365 , Zoho Pro etc.
1. If your domain is newly purchased then the mail may go to spam
2. The server you are sending email from may have a bad IP reputation because you are using a shared host.
3. Hosting servers are usually setup for normal email use, so no good protection is used. There are many other such reasons.
We can get rid of spam a lot by using these free like Zoho, Yandex, paid like GSuite, Microsoft Office 365, Zoho Pro etc.
You may be wondering why I can’t use web mail professionally? Because you bought this with money.
Professional use would have been possible with a simple answer-web mail but not so many mail providers had come along. And they do this because you use a professional mail service.
