When you are ready with the campaign to send it is recommended to send the test mail to yourself.
1. Go to Email campaign.
2. Upload .CSV file and select the sending account then write the content of your email including the subject line.
3. After following the above two steps, you will be able to see a “Send Test Mail" button in the stage 1 of campaign.
4. After clicking that, a popup will prompt up, enter your email address and hit the send button.
Note: Please note that links within test email will not work as it is only for the preview purpose. However your email link will perfectly work in actual emails.
