Do you avoid using spammy words in emails?
Last updated by Brady Stroud [SSW] over 1 year ago.See historyWords matter, especially in email. Spam filters are increasingly sensitive, and even internal corporate emails can get caught if you're not careful. Worse still, your email may look unprofessional or overly “salesy,” which reduces trust and engagement.
Outlook by default reads your emails and can flag your email as potential junk email, or adult content email by examining a list of sensitive words. This list is not available to the public.
Words like “free”, “urgent”, “guaranteed”, “click here”, or “buy now” (especially in uppercase or with exclamation marks) can cause your message to be marked as junk, even if it’s legitimate.
✅ Tips
- Write with clarity and purpose, not hype
- Avoid overly promotional language
- Limit exclamation marks and ALL CAPS
- Check the tone with a colleague or a spam-filter tool
