We regularly send mass mailers to our registered users. Mails are only sent to users who are registered on our website or those who have subscribed to receive the mails. We have a valid unsubscription policy as well as and remove users from our list as soon as we receive the details.
Currently mails to Yahoo are getting delivered in the Inbox but mails to Hotmail continue getting into SPAM and from yesterday even for some users in Gmail, mails have started going into SPAM.
Hello,
We will need to check all the details of the server and/or of the website as to why mails are being tagged as spam and alternatively come up with an alternative. I believe that I can provide some insight to it , especially having been working in the similar field for about 2 years now.
