Two kinds of trip

Customer marketing and sales outreach share one engine for contacts, events and journeys, and each keeps its own rules. Drag the row, or use the buttons below it.

What it does

Your first week

Most of the work is connecting accounts you already have. Nothing is migrated to a new sending network, because there isn't one.

Your carriers, not ours

Hermeticor sends through Amazon SES, SendGrid, Mailgun, Postmark, Resend, any SMTP server, Gmail, Microsoft 365 and Twilio. You bring the account, so the sender reputation stays in your name and the provider bills you, not us.
