Hi Sean,
I apologize for the delay. This usually happens when content for the email has been copied and pasted from another source such as Word or another email without using our "Paste as Plain Text" option. Do you know if this is the case? We always recommend pasting as plain text and then formatting the text within the email template editor to ensure the most consistent results.
Please let me know how you generated your emali and we can go from there.
Thank you!
