The email app preview lets you check your email as seen by the recipients before sending. Optimizely works with an external service provider to create email app previews.

To create or view an email app preview, open the Optimizely Campaign [menu bar](docId\:PmNPgvNucBrAG5Rw8f41f) and select *Analytics > Email App Preview*.
