Description

SMTP Debug is a free and secure tool that can be used to diagnose SMTP connectivity issues. This tool connects your SMTP server and initiates a testing session. It then provides a detailed log detailing the interaction between servers. This tool simplifies troubleshooting, and helps resolve sending issues, whether you're using popular services like SendGrid or Google SMTP. Your information is private and secure with end-to-end encrypted communication. The tool does not store session logs or credentials. You can enhance security further by changing your password or using the optional SMTP Blackhole feature.

Description

Zyntra simplifies email testing for both automated and manual QA processes. For automated testing, it offers temporary mailboxes that provide unique email addresses for each test run, ensuring isolated and predictable test environments. With seamless integration into your existing testing workflows, Zyntra eliminates issues like flaky inboxes and unreliable email services. For manual testing, Zyntra provides persistent mailboxes with long retention periods, enabling easy tracking of multi-step processes and collaboration across teams. It also integrates with various testing tools via API or UI for fast and reliable test email retrieval.
