ONE ADDRESS.
A REAL REPLY.
No contact form, no ticket queue, no chatbot. Write to hello@protagx.com — a person reads it and replies within one working day.
THE FASTEST WAY IN.
hello@protagx.comEvery message to this address lands with the team building CMP42 — not a sales pipeline, not a marketing list. We do not add you to anything because you wrote.
PICK THE RIGHT SUBJECT LINE.
Each link opens your mail client with a subject line already filled in, so your message reaches the right place first time.
Design Partner application
The quickest route is the application form — it asks exactly what we need for the 15-minute call. Prefer to write freeform? Email us with the subject CMP42 Design Partner Application.
Data protection request
Access (Art. 15 GDPR), rectification, erasure or any other right under Art. 15–22 GDPR. Send a request — no special wording needed. Your rights are explained in the privacy policy.
Press and media
Writing about headless CRM, MCP or AI agents in B2B? Get in touch for background, quotes or a conversation with the founder. The launch announcement is a good starting point.
Partnerships
Agencies, consultancies and tool builders who want to build on CMP42 or bring it to clients. Tell us what you have in mind and who it serves.
Security and AVV / DPA
Security questionnaires, the data processing agreement under Art. 28 GDPR, hosting questions. Ask us directly — and see the security overview first.
Anything else
A question about the product, pricing or the roadmap? Check the FAQ — and if the answer is not there, just write.
WHAT MAKES A GOOD FIRST EMAIL.
- Say who you are — your name, company and role.
- Be concrete. Two or three lines on what you are trying to do, or what is in the way today.
- Mention your stack if it matters: the CRM or spreadsheet you use now, the AI tools your team relies on.
- Skip the attachments unless we ask. Please do not send personal data about third parties.
EMAIL IS ENOUGH.
A contact form means scripts, spam protection and usually a third-party service that sees your message before we do. Email needs none of that. It also fits how this site works: no cookies, no tracking, no third-party scripts.
The Design Partner application is the one exception, because it asks structured questions. It is on the Design Partner page.
LETTERS WELCOME.
