Why do emails end up in spam if the body of the email contains a domain name?

Question

gmail

I send it to google mailbox. The html email template has an img tag with a link to the site logo, a link to the site (restoration, mail confirmation, etc.) and in this situation I find letters in spam. If I remove these two links or change the domain to any other - everything is OK. At the same time, at the end of the letter there is an email address of the support, which also contains a domain name - it does not respond to it. Google does not like exactly the domain (c .com at the end). What to do? To whom to write? I found several random sites that check the domain in the blacklists - everything is ok there.

Answer 1

Apparently the domain is not too trusted, Google reacts to links. Less response to email.

Answer 2

There is a generally accepted set of measures that significantly reduce the likelihood of messages getting into spam - a reverse zone at the mail server IP, SPF / DKIM records, a properly configured relay.
Of course, the insides of the message are also checked, but IMHO, if all the general recommendations are followed and the letter is not outright spam, problems are quite rare.
Links to your domain or to some left? Perhaps the domain you are referring to is considered suspicious by Google.

Answer 3

Open the letter in the Google Web interface, above the letter there will be a line with a yellow background and the reason the letter was classified as spam.
