We barred them! They need to clean their act up! 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.

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.

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.

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.

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.
