The first step when creating a campaign with Hunter is to select the email sender(s) in the From box.
Once you choose the email account(s) from where the campaign will be sent, the sender's name(s) will be automatically displayed and match the name displayed on your email account(s).
If you'd like to change the sender's name to something different (for example: only include your first name; remove the middle name; include a first name and a last name initial), it's possible to do so in a few steps if you have a Gmail/Google Workspace account:
Go to the Campaigns Settings tab and click on Email Accounts to view your currently connected email accounts;
Select the email account associated with the sender's name you'd like to change and click on Edit;
In the section Sender name, you can edit the current name to a different one of your choice. To save the changes, click on Update.
When you create a new Campaign, the sender's name will display the latest change.
