This company are now sending spam mail to addresses that have never signed up to. As the email receiver aka the customer I can only give one star. Wish this could be more policed or penalities issued.

Over a long period we've frequently noted .sparkpostmail.com as the sender host for persistent spammers... which tells us the 'service' is basically unpoliced; undermining the credibility of legitimate users! This has been getting worse in the last year or so! - So frequent is the annoyance that we now BAR all email which has the string .sparkpostmail.com in any header via a Cpanel filter! I'd think twice about using this 'service' unless you want to find your messages trashed along with the Nigerian Princes, 'one weird tricks' and shonky viagra sales.

Absolute garbage company! How the heck do we stop spam from your servers? I'm getting sick of my email address and details being passed around (violating GDPR) from one spammer to the next, all helped along by this bunch of cowboys.

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.

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.

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.

In my 42 years I have dealt with a LOT of support. SparkPost and more specifically the PowerMTA bunch are hands down the best support I have had during that time. Thanks and keep it up! - Daniel Thorpe (Spotler Group)

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 !
