SparkPost reviews

SP is very intuitive. I am not a techy by any stretch of the imagination but am by default the "go to" in our office for management of emails. SP integrates into our CRM flawlessly, and we have only on a few occasions had to log into the master account to troubleshoot issues.

I liked the simplicity of setting up and the possibility to manage sub-accounts.

- Alessandro R. Software Developer

By integrating SparkPost's API with our database and marketing automation tool we are able to run user verification and engagement campaigns. Sparkpost has the best email delivery rate. Documentation that is clear and complete and great customer service.
