Quick Answer

The best cold emails in 2026 are short (under 90 words), personalized in the first line, ask one specific question, and have zero links or attachments on the first touch.

• Subject line ≤ 40 characters, sentence case
• First line references prospect-specific fact (not "Hope you're well")
• One CTA, framed as a question

What Is a Cold Email Template?

A cold email template is a reusable message skeleton where only the first line and CTA change per prospect. The body remains consistent — making it easy to A/B test and iterate.
