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 !

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.

Spammers Spammers. I have NEVER given them permission to send me anything, let alone never ending SPAM.

Robust emailing with PMTA We have partnered with Spartpost ( PMTA) since 2014. We send multiple emails in millions to our end clients. And with sparkpost we need not to worry about emails. Support team is also very prompt and resolves our concerns immediately. Thank you Sparkpost.
