The "From" step in campaign setup
When you build an email campaign, one of the setup steps is labeled From. It contains a dropdown labeled Select a Sender. Each option shows the sender name and email address in the format Sender Name <email@yourdomain.com>. Selecting one sets both the from name (what recipients see as the sender) and the from email address for the campaign.
The list only shows verified email identities. If your desired address is not in the list, you need to add and verify it before you can use it.
Where the sender name and address come from
The dropdown is populated from your organization's verified email identities. Each identity has two parts:
Sender Name - the display name that appears in recipients' inboxes
Email Address - the address the email is sent from
You manage these at Settings > Verified Emails. Click Add New Verified Email to add an address. You must enter both the email address and a sender name. Free email providers (gmail.com, hotmail.com, yahoo.com) are not supported; you must use an address on a domain you control, such as info@yourcampaignforcongress.com.
When you add an address on a new domain, verification requires you to add DNS records to prove you control that domain. Once the domain is verified, additional addresses on the same domain are verified immediately without further DNS steps.
Setting a default sender
In your verified email identities list, one identity can be marked as the default. The default identity appears first in the sender dropdown when setting up a new campaign.
Reply-to address
The reply-to address is stored per campaign. There is no separate reply-to field visible in the campaign setup UI; replies from recipients go to the from address unless your account has a reply-to configured at the campaign level through another path.
