Overview

About Koldemails

Koldemails is a free, no-signup toolkit for anyone doing cold email or outbound GTM. It includes a bulk email verifier, a spam-word checker with one-click fixes, a spintax generator, a cold email cost & ROI calculator, a domain name generator with live availability, a domain age & health checker, a competitor infrastructure spy, and a cold email generator — plus free, ready-to-use lead lists by vertical (Y Combinator, law firms, e-commerce/Shopify). Every tool runs entirely in the browser, so your lists and emails are never uploaded to a server.

Unlike most cold email tools, there is no signup, no credit limit, and no paywall — it is genuinely free.
