SparkPost Review

SparkPost supports both SMTP and REST APIs and has client libraries supportings many languages including nodejs, python, php, ruby, go, elixir, and java.

SparkPost delivers more messages to the inbox than any other provider, not just to the recipient, to the actual inbox. So while almost every company will claim high 90's on deliverability, Sparkpost is the only one that's been able to demonstrate high 90's on inbox placement as well. This has real revenue impact.

The support team at SparkPost is extremely responsive to questions and goes above and beyond to solve any challenges and help customers get the most out of their messaging.
