You’re required to have one primary email address on your account to receive emails from Threads and will be associated with your account.
You can add other email addresses to your account to make it easy for people to find you, and so you can join organizations that have specific email domains associated with them.
To add an email address to your account:
- Click on your profile photo on the top-left side navigation
- Select Settings
- Go to the Account emails tab
- Go to Add email addresses and add an email address to your account
