Form Emails

I have an automated email set up to notify certain individuals when a form has been submitted. This email shows the columns and information entered line by line so that the receiver of the email can easily read this information. This has been working fine until a user submitted two forms one right after the other (probably within a minute of each other) and the email showed the information in a different format. Instead of saying one row has been added followed by the columns i want displayed, the email indicated that two rows have been added and showed the information from both forms in a scrunched up format. Has anyone else experienced this problem? Do they know how to prevent it?

Thanks,

Miles
