Yes. Email Marketer's "direct delivery mode" doesn't use your mail server or your
ISP's mail server. Instead, It connects and sends messages to the mail server of
the recipients' address. For instance, a message from email@example.com is sent directly
to mail.aol.com instead of mail.yourdomain.com. This takes the load off of your
mail server and speeds up message sending significantly.
Note: If your ISP (or firewall) blocks TCP port 25, Direct Sending won't work.
