Display Properly Across All Clients by Testing Your Emails, Every Time

Email on Acid’s email previews are on live clients—not emulations—so you see exactly what your subscribers see. Using mobile, desktop, and web screenshots for exceptionally accurate results, there’s no question on what your message will look like in the inbox. By testing every email, you’ll preserve your reputation and avoid the extra work of sending an “oops” email.
