For developers & platforms

Tools for your stack.

The Hamcut Ecosystem isn't just what runs behind LeadSourcing's own campaigns. Every tool is API-first and works standalone, wired into your own product or platform, under your own brand, with nothing pointing back to us.

Seven checkpoints

Pick one tool, or run the whole pipeline.

Each tool does a single job well and can be called on its own. Together they cover the entire outbound lifecycle.

01 Find

FindValidEmail

Source verified addresses from a name and a domain.

02 Enrich

Enricher

Confirm a contact's title and company are still current.

03 Validate

InboxSense

Screen every list against a spam trap database.

04 Audit

DNSPulse

Pull the abuse history behind your sending address.

05 Write

Writer

Turn long content into copy people actually read.

06 Score

Hamcut

Score tone and rewrite anything that reads as spam.

07 Send

Mailheight

Sequence, send, and protect sender reputation.

Standalone & white-label, by default Every tool is wired in through API, entirely under your brand. Nobody downstream, not your users, not your customers, ever sees the name of what's running underneath. It doesn't need to be seen to do its job.
