Our requirement is to send weekly newsletters to our website customers. For which we wanted to have local hosted SMTP server in our office. We are not using SMTP server provided by website hosting provider, as we wanted to reduce the network traffic and avoid IP blocking due to bulk mails.
We are sending newsletters on weekly basis from our local SMTP server. But due to some reasons, some emails are going to spam and some are not reaching to customers and sometimes there are bounce messages to follow bulk email guidelines (mainly from Gmail).
Can you please suggest me, how to achieve my problem. I also wanted to know what type of technology generally Linkedin or banks uses to send notifications emails to all its customers. When they send bulk emails, they will always reach inbox with out any problem.
I want the same solution to implement for my website. Please suggest me.
Thank you very much in advance.
