E-mails we send keep getting blocked or going to recipients spam folders
Posted on 2015-01-23
We have a rather strange issue which has just started happening in the last week. When we e-mail around 70% of our clients our e-mails either get blocked or go straight to the recipients spam folder. I have checked our domain and e-mail server IP on MXtoolbox and DNS stuff blacklists amongst other sites and we are not listed on. Any advice on this would be most appreciated.
