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.

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!

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 !

Literally the worst Literally the worst. Do not waste time and money on them. The support is good for nothing. 1 whole day with their support repeating the same steps over and over again but still not able to setup account. Took 2 mins with mailgun to do the same. Wasted 1 day of my life. AVOID SPARKPOST.

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.
