Retarus Transactional Email vs ZeptoMail
Both stand on transactional email software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Consider Retarus Transactional Email if your organization needs transactional messaging from business applications, API and SMTP interfaces, and the listed monitoring and security features. The main reason to look elsewhere is that the paid service requires a pricing request, while the trial has volume and throughput caps.
