Setting up an email newsletter needs a lot of time, effort, and patience. You will write the content, design the template, add some few links, and test for grammar and typo errors. When you are done with your newsletter you will run an email test to check what it would like to appear when your clients received your email. So that’s the basic process, but the problem when you forward your newsletter to your customers, it is not 100% sure that all of them will receive it. You are asking why? It is because of several factors.

One of the factors included is the Spam Blacklist filters. It happens when your email server I.P. is blocked, flagged or tagged by blacklisting filters. Each email message is given a SPAM Score and normally rated 1 to 5. A score of 5 is the highest score which will more likely your email will be caught by spam filters and a score of 1 which means that it can pass blacklist filters. There are chances that the newsletter which have sent is sent to your verified subscribers but still the Spam filters would block these messages by mistake and this process is considered as ‘false positives’ which is a very big problem in email marketing because maintaining a lists of subscribers would cost you decent lots of money, time and effort. If your mailing server has already been caught, you could then find a good white listing service on the internet to fix the problem.
