Amazing customer service! Amazing customer service! I had never heard of DKIM before, but they helped me generate a key, send it over to our devops to add it to our DNS, and validate it in Sparkpost in no time. Very quick back and forth.

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.

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.

All sparkpost email goes to my spam… All sparkpost email goes to my spam filters. It is therefore a waste of time and money for anyone who is sending me stuff through their platform. I wouldn't be interested in anything offered by an organisation foolish enough to use it so seems like a pointless business from where I'm sitting.

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.
