Hello, I'm Brad, an Email Expert and since you've tagged "MailChimp" as a project skill, maybe I can be of assistance!
I understand you require a solution to send newsletters to your database, sanitize your database (I.e. remove dead Email addresses and report on the click through rate of sent campaigns.
MailChimp enables you to do all this and more!
I have more 5 star feedback for MailChimp than any freelancer on Freelancer.com and have experience designing and coding templates, creating campaigns, managing lists, and setting up automation.
Would it be too much trouble if you could please send me a quick message to discuss your requirements further?
All the best,
Brad M
