The Campaign Details interface allows you to:
Enter the email address you want to send your newsletters from and the address you want replies to be sent to.
You must use an email account that belongs to your domain. Email addresses which do not reside on your own domain will be rejected. For your convenience, you can verify the validity of any email address you enter by clicking on the "verify" button beside each email field.
You can verify if you have entered a valid email address by clicking the "verify" button. If your email address is valid, a green checkmark will appear to the left. If it is invalid, you will see a red "X".
Indicate if you are sending a single newsletter, or of you plan to send a series of newsletters.
Select whether or not you want to send your newsletters in HTML format, or provide a clickable link which will take subscribers to a URL where the newsletter can be viewed on a web browser.
When you are finished, click "Apply" to save your changes.
