Quillbot

Quillbot is known for its paraphrasing and grammar tools, but its AI Email Writer is a free feature that generates complete, professional emails. You can set the tone (formal, casual, confident) and the AI adjusts accordingly. It handles work correspondence, sales outreach, and personal emails.

The free tier makes it accessible for anyone, though the email feature is simpler than dedicated cold-email platforms. It fits best if you need occasional email writing help alongside Quillbot's other tools, not if you're running high-volume outreach campaigns.
