Newspapers ads, radio commercials, e-mail messages and more compete for our attention. Potential customers are in a hurry. Your marketing message must be easy to immediately understand. Keep sentences short. Avoid writing sentences that require a comma.
Commas are the sign of a more complex sentence that takes more time and thought to understand.
Use plain, short words. Write the same way you talk. Keep paragraphs short with some white space between them. Try not to front load sentences. When you see a sentence like this, it's front loaded.
