Email platform and ESP feeds

Feed your email and nurture platform with the right people, in the right segment, automatically.

WHAT IT IS

Manual list uploads are where good targeting goes to die. We connect the source of truth to the sending platform: segment membership, suppression, consent status, and enrichment fields kept current on a schedule.

Deliverability is part of the build, not an afterthought — hygiene, bounces, and unsubscribes flow back so the list gets cleaner rather than dirtier.

WHO IT'S FOR

Teams re-entering the same data in two systems
Organizations whose platforms do not exchange information reliably
Businesses delivering records or audiences to partners and platforms

WHAT YOU GET

A documented interface design with ownership of each field agreed
The built connection, authenticated, permissioned, and rate-limited
Error handling, retries, and logging so failures are visible
Documentation and monitoring, so your team can run it

HOW WE WORK

Understand

We learn how this works for you today, from the people involved in it.

02
Design

We agree what good looks like, who owns which step, and how success is measured.

03
Build

We deliver the work in a narrow first slice you can see functioning.

04
Evolve

We measure it, correct it, and widen it only once it holds.

COMMON QUESTIONS

Is this secure?

Credentials are vaulted, access is scoped to what the job needs, and every call is attributable. Least privilege is the default rather than an upgrade.

What happens when something upstream changes?

Monitoring surfaces the failure quickly and the interface is documented, so the fix is a change rather than an archaeology project.

How is email platform and esp feeds scoped?

From the data flow and the owners first, so the estimate reflects what has to move and who decides, not how many endpoints there are.
