Cold Email Subject Line Generator

A cold email's subject line does one thing: get the email opened. These eight variations cover curiosity, specificity, urgency, and relevance — the four levers that actually move open rates. Fill in your details and pick the angle that fits your prospect best.

What makes a cold email subject line work

The best cold email subject lines are short (under 50 characters), specific to the recipient, and free of triggers that scream "marketing email" — no ALL CAPS, no excessive punctuation, no words like "FREE" or "URGENT". The goal is to look like a message from a person, not a campaign.

Personalisation matters more than cleverness. A subject line that mentions the company name or references a real pain point consistently outperforms a generic but witty one. Use these eight variations as a starting point, then test two or three against each other to see what resonates with your specific audience.

If you want help writing the actual email body — or want more than five generations per day — message me on WhatsApp. That's what the button's there for.
