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.

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.

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.

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.

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!
