We decided to test this service based on a colleague's recommendation. It seems we followed all the instructions, but when we checked the functionality by sending an email, we encountered three errors. When we asked for help on how to fix them, the tech support sent a standard response. Thanks, now I’ll be looking for a solution on Google. Good thing we didn’t manage to make a payment. All the positive reviews seem to be fake. Disadvantages: — The site is constantly down — Tech support does not respond. P.S. I tried to take a screenshot of the tech support response, but their site is down again.
