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 !

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.
