About

We built the desk between your process and their ESP

Agencies already pay email providers. Clients already own domains and reputations. The missing layer is operations: one place for workspaces, approvals, deliverability, journeys, and client-ready proof — without inserting another meter on every message.

The problem we started from

Agencies were stitching Slack + Docs + N ESP logins + screenshot PDFs. End-business tools optimized for one brand. Raw SES optimized for engineers. Nobody owned the multi-client desk.

What we chose not to build

We’re not a CRM, SMS suite, or “another Mailchimp.” Diluting the wedge helps no one. Email ops for agencies is the product.

How we measure “better”

Shorter time-to-first-test-send, approvals that leave chat, fewer blocked launches, more shared reports under the agency brand, and paid conversion when seats/clients/events actually constrain you.

Who it’s for

Digital agencies drowning in context switches

Web, performance, and full-service shops (and freelancers scaling into agency ops) managing roughly 5–40 email clients — especially teams already on SES or tired of multiplying Mailchimp bills.

Owner pain

Margin + proof

Per-contact SaaS × N clients. Reports that look like the vendor. No single pulse across the book of business.

AM pain

Wrong login, wrong day

Context switching, Slack approvals, blocked sends discovered too late, no one next action.

Client pain

Friction to say yes

Asked to log into tools they don’t understand. Monthly results arrive as screenshots.

What we refuse to be

  • Another end-business ESP competing on templates alone
  • A CRM / SMS suite that dilutes the email ops wedge
  • A thin “multi-brand” skin that still marks up contacts
