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.

SparkPost is one of the best places for… SparkPost is one of the best places for anyone looking for robust and reliable mail services. Great control panel, awesome metrics, and unrivaled API power and flexibility. I'm one of their happy customers since years, and going to remain for decades to come.

Stellar Support and Reliable Platform! Sparkpost's support and general service is always stellar. They consistently go above and beyond and are quick to reply to our support inquiries. Over the years we have seen great product improvements, some of which we were given an opportunity to provide feedback on prior to launch which has always been taken seriously. In addition to their support team, we have been extremely impressed with how well other teams at Sparkpost have partnered with us when issues have come up. Their Technical Account Managers and Deliverability Teams are made up great folks who are always willing to advocate for us or hop on a call to work something out. As a longtime user of the platform, we feel fully supported by both the people of Sparkpost as well as the platform. Would highly recommend them as a service provider!

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!

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.
