Good list of suggested plugins for various newsletter but the problem is that no one has yet subscribed for the newsletter yet, so it will not be any use to me. Anyways thanks for sharing mate.

Hi Emil,
Thanks for the list. Just wanna ask if any email service provider blocks newsletter email sent through any of these plugins?
I am making a little research before I use one of them.
Thanks,
Joe
That all depends on ISP
Please see http://sendpress.com as well.

Joe, emails sent with a plugin can get blocked. That all depends on your sending method.
At Wysija, we recommend sending with a professional sender. Read our FAQ on deliverability here:
