I am looking to email 8000 users on a daily basis, emailing them about every 2-3 days by deleting old users and importing new ones. I am looking for a good email marketing solution that would send emails to my users' inbox and not mark them spam. I am looking for softwares only, or a good and cheap site thanks.
If you want to learn a good hint on how to work with your e-mail correspondence, you should know that big companies suffer from enormous sizes of their e-mail database. If you have the same problems, it might be interesting for you to learn the way to convert messages to pst. This cloud service has proved itself to be really convenient in our office structure.
Really good solution is to buy some database in a place like this: getdb.net or even talk to these guys and they will scrab everything for you under your request. And you will reach your hot potential customers.
