On top of the usual QA to confirm the test email matches your signed-off version, we check all functionality to spot anything that’s wrong. For example anything from a missing space to a pixel error in an image.
Yes, we use the best machine tests for your emails, but that isn’t good enough for us. Or you. When we receive the final tests, we run through ISP-specific QA tests. After that we go above and beyond and run manual checks on a wide range of devices, both current and previous versions.
Only then, when our email Quality Assurance team are 100% happy, we approve your email for deployment.
