How important is grammar and spelling?

Errors damage credibility and trigger spam filters. Grammar mistakes signal carelessness-if you can't proofread an email, can customers trust your product or service? Certain typo patterns (common in spam) can contribute to filtering. Professional brands proofread professionally.

That said, voice trumps textbook grammar. Sentence fragments for emphasis? Fine. Starting with \"And\" or \"But\"? Acceptable. Casual contractions? Often preferred. The goal is clarity and connection, not passing an English exam. Write how your audience speaks.

Perfect grammar matters less than perfect proofreading. One typo in a thousand sends reaches thousands of people. Broken personalization (\"Hi \") is worse than a minor grammatical choice. Build proofreading into your process: spell-check, human review, test sends. The embarrassing error is always the one you didn't catch.
