Questions & answers about spam checker

Everything you need to know about SPAM.

Spam Checker looks for spam trigger words in your email. Spam words are keywords or expressions that email service providers see as red flags.

We divided spam keywords into 5 main categories:

  1. Urgency 🚨 - words that pressure recipients
  2. Shady πŸ”ž - ethically or legally questionable words
  3. Overpromise 🀩 - exaggerated claims
  4. Money πŸ’° - all things related to money in general
  5. Unnatural πŸ’¬ - words that don't feel natural

The spam checker tool will highlight words that could be avoided or rephrased in your email. To do so, we compiled the most exhaustive spam words list to avoid in your emails.

Remember that if your copy contains one or a few spam words, it doesn't necessarily mean your email will be considered spam. Using words in their context is fine.
