Yes! If you'd like to send an email marketing campaign to yourself or to a group of friends to give you feedback on it, you can do so very easily.
First, you'll need to create your campaign. Click here for a guide on creating a campaign.
When your campaign is ready, click on the send button. After that, click on the email test button and a window will appear. Enter your email (or the emails you want to send the test to) in the box labeled send a test to and click on send.
After your email test has been sent, you'll receive an email just as your customers will when you send it to them.
