Test Emails Before They Hit Production
Keep staging and production email completely separate. Verify every email template works perfectly before deploying.
Get Started FreeStaging email testing is risky
Mixed environments
Staging emails accidentally sent to production addresses. A nightmare to debug.
No visibility
Hard to verify what emails look like in staging before deploying to production.
Team coordination
Multiple team members testing at once. Whose email is whose?
Template issues
Broken templates slip through to production because no one checked staging.
How InboxSim Helps
