While I do like the interface of StreamSend and the ability to save campaigns and lists over time, until we have a need to distribute a much larger scale of email counts, our budget would make use of a free alternative.
The renewal process is easy and doesn't require much thought. Our accounting team already has Streamsend as an approved vendor. We are happy with Streamsend and how it works. Switching email systems would require training and a learning curve that will be difficult to schedule in a busy department. The quality and reliability of Streamsend is something our team and attorneys trust.
