1. Go to Emails > Email Campaigns.
2. Click on the name of your in progress email campaign.
3. You'll be on the Settings tab of your email campaign.
4. Paste in the utf-8 symbol in the subject line field and then type in the rest of your subject line.
5. Click Save on the Settings tab of the Campaign.
6. Test your email across multiple email clients to ensure the symbols renders appropriately.
