Free B2B outreach tools
Practical, free, no-signup tools that run in your browser. The same checks we run before we send a single email for clients.
Cold email spam test
Send a real email to a test address → SPF/DKIM/DMARC verdicts, content and formatting checks → score out of 10.
Open tool →Deliverability checker
Enter a domain → SPF, DMARC, DKIM and MX checked → 0-100 score and exactly what to fix.
Open tool →Cold email audit
Paste a cold email → instant score on length, spam words, links, tone, ask and subject.
Open tool →ICP & targeting analyzer
Six quick questions → your targeting maturity score and your biggest gaps.
Open tool →Which tool answers which question
The four tools cover the three things that decide whether a cold campaign works, and they are worth running in a specific order.
Start with targeting. The ICP and targeting analyzer is first because no amount of copy or infrastructure work rescues a list of the wrong people. If it scores low, fix that before anything else — the other three tools will happily tell you that a well-written email from a healthy domain is going to the wrong audience.
Then the infrastructure. The deliverability checker reads what your domain publishes: SPF, DKIM, DMARC and MX. It answers "can receivers verify me at all?" — a question that has to be yes before anything else matters. The spam test answers the harder version: you send a real message and see what a receiving server actually did with it, including whether the signature survived and aligned. Records can look perfect while real mail still fails, which is exactly the gap between these two.
Then the message. The cold email audit scores the copy itself — length, links, tone, the ask. It is last on purpose: it is the layer teams instinctively reach for first, and the one that can do the least when the two below it are broken.
What these tools are not
They are diagnostics, not monitoring. Each one is a snapshot, and the things they measure drift: DNS gets edited, domains accumulate reputation, lists age, copy decays as recipients learn the pattern. Re-run them when something changes rather than treating a good result as permanent.
They also do not need your data. Everything runs in your browser or against public DNS, with no signup and nothing stored — the exception is the spam test, which by design receives a message you send it and keeps the report for seven days under a random ID.
If the tools point at problems bigger than a quick fix, the blog covers the underlying work — deliverability, targeting, copywriting and sequencing — in more depth than a score can.
