Put any group of senders together and the conversation invariably turns to discussions of how to get email delivered to the Inbox. There is an underlying flavor to most of these conversations that is quite sad. Many senders seem to believe that the delivery of their email is outside of their control and that since the ISPs are difficult to reach that senders are stuck. The ennui is palpable.
I am here to tell you that nothing could be further from the truth!
Senders are not passive victims of the evil ISPs. In 99% of cases, delivery problems are fully under the control of the sender.
Mail being deferred? Mail being blocked? Mail being delivered to the bulk folder? Senders do NOT NEED TO CALL THE ISP to fix most of these. Tickets do not need to be opened nor do personal contacts need to be employed. You can resolve the vast majority of problems with data you already have.
