Trial ? Worth pursuing. It is important to understand how to build up this capability. Enterprises should try this technology on a project that can handle the risk.

Using test email accounts or entire test SMTP (Single Mail Transfer Protocol) servers remains a common software testing practice. However, using a real server carries the risk that test emails will be sent to real people and often complicates automated integration testing. We've seen success using a fake SMTP server to test mail sending, which records a request to send an email without actually sending it. Multiple open-source tools exist in this space, including fake-smtp-server, which renders emails in a web UI for visual testing, and mountebank, which exposes the sent emails through a REST API for integration testing. We recommend exploring this technique to reduce risk and improve testing efficiency.
