We started using MessageBird when we were just starting out. We are now sending thousands of messages a day without any problems. They even reached out to give us a better deal. Great people, can't recommend them enough
I found this service via web search. I took the risk and bought their smallest message package for $15. I happened to use my corporate PayPal account because the personal one didn't have any funds - I even sent a message to the person who was supposed to be my personal assistant regarding this and he said no problem. I waited for them to confirm my purchase and update my account. 4 days after the purchase, i got a message from the personal assistant that they could not verify my purchase. I waited 3 days then replied to him asking why they were still holding on to my money if they couldn't verify the purchase. No reply for a week now and no money
