Email providers like Google and Microsoft use content-based filtering to detect spam. Certain words and phrases — like "free," "guaranteed," "act now," or "limited time" — are strong signals that trigger spam filters. When your cold email contains multiple spam trigger words, your deliverability drops significantly.
The optimal approach is to write cold emails that sound like genuine one-to-one messages. Avoid promotional language, excessive capitalization, and urgency-based phrases. Keep your emails short (50–125 words) and conversational.
