Why retention agencies work with us

Retention agencies are unusual — they mix high-frequency execution (every campaign, every flow, every send) with deep strategic judgement. Most staffing partners are good at one side, not both.

Staff Stack is built for this mix:

  • StackCertified execution roles (Klaviyo Ops, Copywriter, QA) handle the weekly build + send cycle.
  • StackCertified Lifecycle Strategist takes the day-to-day strategy ops off your senior strategist's plate.
  • Every operator is AI-trained on Klaviyo AI, Claude, and ChatGPT — so they move at the speed you need, without generic output.

Typical team shape

A 15-retainer retention agency usually starts with:

  • 1 Lifecycle Strategist (covers 5 accounts)
  • 2 Klaviyo Ops (covers 8–10 accounts each)
  • 1 Email Copywriter (shared across all accounts)
  • 1 QA Reviewer (shared, runs pre-send checklist)

Scale up from there in 2-week increments as the book grows.

What it's not

If you're looking for a single "Klaviyo VA" for a few hours a week, we're the wrong fit. Our model is dedicated operators, integrated into your delivery team — not freelancers.

Retention agencies on Staff Stack typically add 3–5 new retainers in the first six months without adding senior headcount.
