Free tools for recruiters

Free tools that each do one recruiting job well: build a Boolean search string, check a cold email for spam words, clean a lead list, see which tools work with your ATS, test your domain’s email setup and price your tech stack. No account and no email needed. Every tool runs in your browser, so nothing you type is stored or sent, with one exception: the SPF, DKIM and DMARC checker has to look up your domain’s public DNS records. When you need software to act on the result, the directory lists 1,000+ recruiting, lead gen and HR products.
