While it is not required, it is a good idea to save at least one default From line (a.k.a. Sender Address) for your account. The From line should be no more than 200 characters and the correct format is "Company Name"<emailaddress>. This article will walk through the steps to save a Sender Address to your account to be used with outgoing emails.
- Go to Settings > click "Account Management" > click "Sender Addresses" (left column)
- Click the "Create Sender Address" button (top right)
- Enter Sender Name and Sender Address
- Check "Use as default sending address for this account" (optional)
- Click 'Save' to save
