Partners / written introduction
Begin with a clear conversation.
This is a written contact path for prospective partners. It does not create an account, share trips, show commissions, publish rates, or confirm any commercial arrangement.
Written first contact
A starting point, without assumptions.
Use email or WhatsApp to introduce the conversation. CASTRIAL can respond in writing about the appropriate next step. A written message is not a reservation, agreement, quote, availability confirmation, or account approval.
What this page does not do
No portal, rates, or records.
This public page has no partner account, invite, referral form, trip directory, commission display, payment function, or operational data. It is intentionally limited to direct written contact.
A careful handoff
Keep sensitive details out of the first message.
A short introduction and a preferred written contact method are enough to begin. Do not send sensitive documents or rely on this page for private operational information.
