Send yourself a test before the real send
Updated April 30, 2026
Preview shows you the render. A test send shows you the truth: how the subject looks in the inbox list, whether images load, whether merge tags filled in.
On the Review step of any campaign, use Send a test. Enter up to five addresses. The test uses real merge data from the first matching contact so {{first_name}} is a real name, not a placeholder.
Send a test to a Gmail address and an Outlook address at minimum. They render differently and both matter.
