    • Preheader - An email preheader displays below or next to the subject line in most email clients and mobile devices. It's a great way to support your subject line and further entice contacts to open your email. 
    • From Name - This helps your contacts recognize who you are and keeps your email out of the junk folder. Pick a name that your customers and contacts are most likely to recognize, whether it's the name of your organization, your personal name, or a combination of both.
    • From address - From the drop-down, choose an email address that your contacts will see in their inbox. You can only send from an authenticated domain, so you may not see all of your verified email addresses in the drop-down.

    • Reply-to address - From the drop-down, choose a verified email address to receive replies from your contacts. It doesn't have to match the "From" email address, but make sure it's an email account that you check regularly. All "Reply-to" email addresses must be verified to ensure you're the owner of the address.
    1. ​When you're finished, click Save.

    If you forget to update the header information while in your email draft, you can also edit it when you schedule your email to send.

    If your email is already in a "Scheduled" status, you can unschedule it to make edits to the email header. However, you cannot edit the header information once your campaign is sent. Instead, you can copy the sent email and make your edits to the copy before resending it.
