Free cold email checks that run in your browser, no signup
Four free tools for anyone sending cold email. Grade a domain's MX, SPF, DMARC and DKIM. Flag job-changers in a lead list. Size inboxes and domains for a sequence. Cost a per-meeting quote. No signup. Three run entirely in your browser.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
