Very Bad Customer Support Our company had multiple accounts with them and we started using Sparkpost but the company suspended all accounts at once and after discussing this I told them to refund but they didn't instead they stopped talking and closed the accounts.

Sparkpost & MessageBird are irresponsibles Sparkpost & MessageBird are irresponsibles with their account suspension, they don't care about the impact they can produce to the customers, and they don't care about the service. They cut our service because they didn't answer to more than 25 emails and 15 tickets we opened to inform that we need the payment information which they changed when moved from Sparkpost to MessageBird. They responded 6 months latter with wrong information delaying more and more the payment, but then they cut the service. It is the worse service I have ever received.

No way to contact the company We have been a customer for a while but haven't use the service for some time. Now I would like to cancel subscription but it's impossible as there is no way of contacting them without creating a ticket (and I can't login). These types of services just make you furious.

I am Daily reporting spammers that use… I am Daily reporting spammers that use SPARKPOST and they do nothing about it. Never trust a company that spams and never trust a company that allows spamming via their system !

Absolutely outstanding company to work… Absolutely outstanding company to work with. The customer service and friendly demeanor of the people you will work with every day is without comparison. Not only do they reply super quick when you need something, but they are always there to help you solve whatever problem you can conjure. Amazing!
