Best AI to write cold emails (2026)

Everyone. Seriously -- if you're new to AI or want the most complete all-in-one package, ChatGPT is the default recommendation.

Writers, analysts, developers, and anyone who values quality of output over quantity of features. If you care about how good the actual text is, Claude is the best.

Non-native English speakers, professionals who write lots of emails, and anyone who wants a passive grammar net running in the background. It catches things you'd miss.
