Evaluate how well the software can grow with your business, connect with existing tools, and protect your data. These considerations will help you choose a solution that fits your needs.
Can transactional emails include marketing content?
Transactional emails should focus on delivering information related to a transaction or user action. Including marketing content can blur the lines and require an unsubscribe option.
