If you are sending an email campaign, you must test your emails to ensure they look correct on all receiving email systems—especially if sending from some web-based email systems.
Formatting errors often come from copying text from Microsoft Word into gmail or similar web-based email systems and sending it). If you send a test email to yourself (if using gmail–>gmail) the formatting appears normal. The error most likely is occurring for users opening your emails with Outlook–which a lot of people are using. Other mass email systems often have the same problem.
Example of spacing errors (the first shows what you thought you sent–the latter shows what was received):
