Hamcut flags risky phrasing, lookalike links, and AI artifacts before you send. Paste content in the editor or call the API to get fixable chips, a clean rewrite, and a JSON audit. Shift deliverability left and ship safer campaigns in minutes.

Why we built it
Deliverability fails more on content than DNS. Hamcut runs a dual-model check (Model A and Model B) on your draft, surfaces top spam/ham tokens with weights, and flags AI artifacts and lookalike URLs—so you fix copy risks before any filter sees them. Run a live test: https://hamcut.com/#run-a-test
.
HamCut:
What’s new in this launch
* Dual model scoring with top spam and ham tokens, weights, and clear thresholds
* Fix chips that turn risky terms and structure findings into direct edits
* URL integrity: lookalike domains, punycode, and redirect checks
* AI artifact cleanup: double dash, ellipsis, emoji, mixed quotes, casing and spacing
* Editor and API parity with a JSON audit for teams and compliance
* Try it now. Run a live check in the editor: https://hamcut.com/#run-a-test
Prefer the API, which is available on Hamcut-Pro plan?
curl -sS https://writer.leadexit.com/api/... \
-H 'Content-Type: application/json' \
-H "X-API-Key: YOUR_KEY" \
-d '{"text":"Subject + body here","with_ai_checks":true,"topk":25}'
We’re here all day. Tell us which checks or integrations you want next and we’ll prioritize them.

The AI artifact detection is super interesting. Did you find a particular type of AI content harder to flag than others?

@rajpurohit_vijesh Raj, thank you for the question. However, hamcut.com does not dig deeper finding those emails that were drafted using AI. Honestly, we don't want to know either :-D
However, if ESPs, Firewalls that inspect these emails and are specifically look for some footprint that shouts out 'AI' then we were interested. So, digging deeper we found some useful artifacts. Here's what we hunt, sharing those here, maybe you will find more ways to use it.
