If anywhere within body of the email I place link to my website in format <a href=http://mywebsite.com>more info here</a> , it gets flagged as spam I tested many different combinations and interesting thing is that it's only link to this particular website (my website) in which case email goes to spam. I tried few other website links, all I changed was href= attribute and email is NOT marked as spam I'm sending email from my hosting to gmail. On web server I have installed postfix and I'm managing email server on my own. I added SPF and DKIM records correctly so I dont think this would cause any problems. This is the same web server where I have website hosted, same website whose link is marked as spam in gmail. Any other emails which I send from this server to gmail without my website link in content are valid and are NOT going to spamNow, could this be related to my site ranking in google? I wonder which factors could possibly use to send emails with my website link to spam. My site rank is not so bad (but not highly ranked either), it's not penalized as far as I know, I used couple of web services to test and it looked fine. It's also indexed properly and I can see it in google search results for relevant keywords If anyone can provide more infos about this I would appreciate it
