Analysis for newsletter and Testing of Emailing Feature of a Website

I have 2 simple tasks: a. Test a really small emailing feature of a small website. - Just need to check if the users are able to send/receive emails each other under various scenarios. You probably create couple of email accounts for testing. - Generate tempory email. b. (Business Analysis Task) A website, sends out newlsletter to their members. Out of 100 products they list everyday, they only select 10-20 in the email. Just need to analyse and try to understand how they select the emails. Above are very basic and simply tasks. We need someone with a very good analytical skills and someone who is thorough.
