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.

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!
