Hi, I created a newsletter template then deleted all but one (my email) in the "client touch" then sent out a newsletter via the 'Email Blast" I did this twice and have not received any emails.
Your email server is blocking your own email address
"10/16/12 09:09 AM Failed: 'Your October Newsletter is here' Server response: 521 5.2.1 Email fails this check...decline" (this was from your email server, I have removed your email address from the error for your own privacy protection)
This happens sometimes (at Gmail for example) when you are sending TO and FROM the same email address, and it's not originating from your REAL email server.
To get around this with Gmail (which I use), I use a non-Gmail account for my test emails. This gives me the added benefit of seeing how another system will format my messages before I send them out.
By the way, I sent your newsletter to myself and it came through just fine, instantly.
