This person is lying. He will take your money and not do anything. Also his own emails are not even delivered, haha how can he provide mailing service when he cannot send a normal email! None of his emails were ever received. I have no delivery problems from anyone except him (i.e. his problem, not mine). He cannot send a regular email to a gmail account.
Also when you buy the service and import a list, you can expect it will load a single page for 10 minutes so it is completely unusable!!! He will not do anything about it for over 6 weeks and say it is your problem. He will not bother to fix it, he will only tell you to pay again to fix it, then you pay and he will not do anything.
