Cold Emails: What Subject Lines Worked Best for Me?

From all the subject lines that I have tried till now, these 3 subject lines have consistently outperformed others in our B2B outreach:

• “Quick idea to improve {{pain point}}”
• “Your competitor {{Competitor name}} tried this”
• “{{First Name}}, saw this for {{Company Name}}”

These subject lines work because they trigger curiosity instead of typical sales emails.

Note: Avoid spammy subject lines that sound like clickbait or fake “Re:” threads.PS. If you want more subject lines to A/B test, then check this: Most Opened Cold Email Subject Lines.
