When you have finished writing your email copywriting, you can send an email to yourself to preview the final design of the email.
The email will be sent from and to the email address that you have configured with your campaign, not to the email address of the account user.
If you cannot find the test email when using the Outlook app, please try to open it on the browser instead as we have seen some users experiencing difficulties in separating their different account inboxes on the Outlook app.
