eDataSource

eDataSource is the industry leader in deliverability technology and email performance insights. The job it does: sending campaigns and automated emails to a list and measuring what gets opened.

The natural audience is marketers at companies of every size. They also list Analytics, Business Intelligence, Email, Email Marketing and Machine Learning, so expect those to show up in the feature set. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

eDataSource is based in New York, New York. You can read more at edatasource.com.
