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.

Absolute garbage company 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.

Absolutely outstanding company to work… Absolutely outstanding company to work with. The customer service and friendly demeanor of the people you will work with every day is without comparison. Not only do they reply super quick when you need something, but they are always there to help you solve whatever problem you can conjure. Amazing!

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

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.
