Our QA team used to spend hours on email testing. Now we just tell Claude to "test the password reset flow" and it handles everything. Docmailer made this possible 🙌

Integrated Docmailer with our Codex setup. AI agents can now receive OTPs, verify accounts, and test notification systems. The free tier is generous too! 💯
