Our verdict

Firstsales.io generates cold emails with GPT-3, drawing on recipient interests and industry to personalize the message, and adds audience insights based on demographics and behavior to sharpen targeting. Tone, structure and calls-to-action can all be adjusted, with built-in A/B testing to compare variations. Because the copy comes from AI, it can misread context, so a human pass before sending is still worth doing.
