Adding or updating a new social media profile to the Brand settings page will only automatically populate those emails that are both:
created after the social media profile link was added to the Brand settings page and
if the email template automatically includes the social block in the default state.
Anytime you manually add a new Social block to your emails, you will need to customize the associated social media URLs within that block.
Additionally, if you have existing emails that include a Social block, and you later update or add a new social profile to your Brand settings page, you'll need to add or update that social media handle manually to your existing emails.
To do so:
1. Go to the email that you'd like to edit.
2. Select the existing or add a new Social block.
3. Manually update the URL for the social media platform to include your handle.
4. Click Save in the upper right corner.
