Free cold email tools
These are the four tools we use on client campaigns, published free with no signup. Every one runs entirely in your browser: your email copy and the domains you check are never uploaded to us or stored anywhere.
Cold Email Spam Checker
Scans cold-email copy against 1,130 spam-trigger phrases grouped by urgency, overpromise, money, salesy and list-mail language, highlighted live as you type, plus link, image, capitals, punctuation and subject-line checks.
Cold Email Grader
Grades a cold email against a working playbook: subject-line tests, the 80-word cap, 606 AI-writing tells, 480 fluff phrases, offer structure and the ask, then applies the mechanical fixes in one click.
Email Deliverability Checker
Checks any domain's MX records, SPF record with its 10-lookup audit, DMARC policy, DKIM selectors, MTA-STS, TLS-RPT and BIMI, graded with the specific fix for each failure.
Cold Email ROI Calculator
Models pipeline from list size, deliverability, reply rate, meeting rate and close rate, so cost per meeting and break-even reply rate are explicit before you spend.
Rather we ran the whole thing?
We build and run B2B cold email end to end, copy, infrastructure and booking, and get paid on the revenue we help you close.
