Do you have problems with sending and receiving your email messages?
Every now and then, important email messages don’t arrive to their destination, or they go to the email junk folder of the addressee.
This problem is even worse for a business that uses email. What do you think, as a buyer, if you don’t receive an answer to a question, or worst, if you do not receive a download link for a book or software you ordered, or assistance with the download?
There is another problem, and this is when people make a typo error in their email address, use an email address that has been closed, or an email account that its email inbox folder on the server is completely full.
If it is a business having email problems, the visitor or buyer might get angry or be unhappy, and could request a refund. He or she might also complain. The business or company wants to give a good service, but they have a problem they need to solve.
