How does your email testing work?

We send your email through each email client application and stitch together a screen capture of the final result. Using this technique,
your email is sent to each individual email client as soon as you
submit an email for testing. From there, test results will return in
the order that they are received and processed.

Screen captures are displayed as one large JPG image so you will
not be able to click on or test outside links, nor can you preview
animated gif images. Instead, check your links with our URL validation feature.

We do not use code-based simulations.
