I'm sending emails but they're not being received. There are no error or bounce-back messages. What's going on?

The most common cause of this problem is that your IP address is blacklisted by the public spam blacklists.  Nearly all email service providers will check incoming email to see if they're coming from these public blacklists first before delivering the message.  If the email is coming from a known spammer or any source that is blacklisted, then the email service provider will simply drop the email message without providing any error or bounce-back message.

In this case, it's best for you to check and see if the IP address for your internet connection is listed on any of the public blacklists.  The first thing that you'll need to do is to find out what the IP address is for your internet connection. You can do this through this link: http://www.doteasy.com/myip/

Next, do a blacklist check by plugging in your IP address using this tool: http://mxtoolbox.com/blacklists.aspx

If your IP address is flagged by any of these public blacklists here, then that would explain why your emails aren't getting through.  You have two options:

1.  You can contact your internet service provider and see if they can remove your IP address from the blacklist.


2.  You can contact your internet service provider and have them assign you a different IP address that is not blacklisted.  This is important because there is a chance that your internet service provider will assign you a new IP address, but that new IP address turns out to be blacklisted as well.  So, be sure to check your new IP address against the public blacklists using the MX Toolbox link above.
