Do you know the best way to point out your merchandise or services? Sending messages using feedback forms can allow you to easily enter the markets of any country (full geographical coverage for all countries of the world).  The advantage of such a mailing  is that the emails which will be sent through it will end up in the mailbox that is intended for such messages. Causing messages using Feedback forms isn't blocked by mail systems, which means it's certain to reach the recipient. You may be able to send your supply to potential customers who were previously unavailable thanks to email filters. 
We offer you to test our service without charge. We are going to send up to 50,000 message for you. 
The cost of sending one million messages is us $ 49.
