Sparkposts support and service is top notch! Sparkposts support made my learning curve about email marketing ins and outs much less steep. THey helped me each time with accurate and fast information or actions. I recommend Sparkpost for anyone looking for mass email sending as they have affordable prices and of course support team is very good and expedite. Keep it up!

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.

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 !

Horrible company that condones spammers… Horrible company that condones spammers and doesn't accept emails to their abuse email address advertised on the website. When you report a spammer they immediately reject the email to their abuse address. This company is in violation of the federal CAN-SPAM act and should be shut down by the FTC.

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.
