Hello @Dr.DavidS3 ,
The online store system, as well as several of the e-commerce integrations available for Constant Contact accounts have various automated invoice / receipt emailing available to them, as well as other automated email types like promos, abandoned cart emails, etc. Is there a specific type of "transaction email" you're looking for?
