SparkPost, email sending platform, agreed to acquire eDataSouce, a provider of email deliverability solutions and performance insights. Financial terms were not disclosed. eDataSource’s inbox performance insights and reputation management will help SparkPost deliver the first fully integrated email sending and analytics platform. “The industry has long accepted a certain level of lost subscribers, however, those stakes are considerably higher based on some of the email provider changes over the last few years. Today, a miss at the sending layer will result in a significant hit to a marketer’s total acquisition costs, and can be avoided by making small adjustments. By combining forces, we can now integrate insights with your sending for direct action and measurement. Our two companies coming together solves this problem,” Rich Harris, SparkPost CEO.
