Stakeholder Briefings: Storevine Campaigns Sprint 12 Deliverability Retro

Scenario

Sprint 12 hit a deliverability problem: a batch of merchant sends on the new dedicated IP landed in spam folders before the warm-up ramp had fully established reputation. The team ran a retrospective and Storevine’s Growth PM needs the learnings to reach three audiences: Engineering owns the fixes, CS/Support fielded the tickets and needs the talking points, and the Executive sponsor needs to know whether GA confidence still holds. The PM runs foundation-stakeholder-briefings against the retro and edits the incident proposal down to Engineering, CS/Support, and Executive (no Legal surface here).

Source: Sprint 12 deliverability retrospective. What happened: a batch of
merchant sends on the new SendGrid dedicated IP hit spam folders because send
volume ran ahead of the warm-up ramp. Inbox-placement dipped before recovering
once volume was throttled back to the warmed ceiling. No data loss, no
compliance issue. Fixes agreed: enforce a warm-up-aware send-rate cap, add an
inbox-placement alert, write a deliverability runbook for support.

Audiences: incident proposal but drop Legal (no regulatory surface) - keep
Engineering, CS/Support, Executive.

# Stakeholder briefings: Sprint 12 deliverability retro

## Master document

**What and why**

- M1: In Sprint 12, a batch of merchant Campaigns sends on the new SendGrid dedicated IP landed in spam folders because send volume ran ahead of the domain warm-up ramp.
- M2: Inbox-placement dipped during the window and recovered once send volume was throttled back to the warmed daily ceiling [fictional]; there was no data loss and no compliance issue.

**Decisions**

- M3: Enforce a warm-up-aware send-rate cap so daily volume can never exceed the current warmed ceiling.
- M4: Add an automated inbox-placement / reputation alert that fires before placement degrades, not after.
- M5: Write a deliverability runbook so support can answer "why did my email land in spam" without escalating to engineering.

**Status**

- M6: Root cause is understood (volume outran warm-up); the system recovered and is stable; the three fixes are scoped but not yet shipped.

**Risks and open questions**

- M7: The same failure mode recurs at GA when many merchants activate at once unless the rate cap is in place first.
- M8: Repeated spam-folder placement, if it recurs, erodes IP reputation cumulatively and is slow to repair.

**Asks**

- M9: From the Executive sponsor, confirm GA confidence holds given the fixes, and that the rate cap is a launch gate.

**Timeline**

- M10: The three fixes land before GA (2026-07-20); the rate cap is the gating item.

## Briefings

--- BEGIN: Engineering ---

**Draws on:** M1, M2, M3, M4, M6, M7, M10

**Primary ask:** Land the warm-up-aware send-rate cap and the inbox-placement alert before GA.

**Volume outran warm-up; the fix is a rate cap tied to the warmed ceiling**

**What this means for Engineering**

Root cause is clean: a batch of merchant sends pushed daily volume past what the dedicated IP had warmed to, and placement dropped until we throttled back to the warmed ceiling [fictional]. The system recovered on its own once volume was inside the ramp, so this is a control gap, not a pipeline defect.

Two builds close it. First, the warm-up-aware send-rate cap: daily send volume must be hard-capped at the current warmed ceiling and step up only as the ramp progresses, so no burst of merchant activity can outrun reputation. Second, the inbox-placement / reputation alert: it has to fire before placement degrades, not after we hear about it from support. The recurrence risk is concentrated at GA, when many merchants activate at once, so the rate cap specifically has to be in place before the 2026-07-20 GA. Land the cap and the alert before GA.

--- END ---

--- BEGIN: CS/Support ---

**Draws on:** M1, M2, M4, M5

**Primary ask:** Adopt the deliverability runbook so first-line support can resolve spam-placement questions without escalating.

**You can answer "why did my email land in spam" now: it is the runbook**

**What this means for CS/Support**

During Sprint 12, some merchants saw their campaign land in spam folders. The cause was internal and temporary, send volume briefly ran ahead of our email warm-up, and placement recovered once we corrected it [fictional]. Nothing was lost and no merchant did anything wrong, which is the reassuring line to give.

The takeaway for your team is that you no longer have to escalate these. The new deliverability runbook gives you the plain explanation and the steps to check a merchant's situation, so the most common "why did this go to spam" ticket can be resolved first-line. Adopt the runbook and route to it for any spam-placement question; escalate to engineering only if the alert is already firing.

--- END ---

--- BEGIN: Executive ---

**Draws on:** M1, M2, M6, M7, M9, M10

**Primary ask:** Confirm GA confidence holds and that the send-rate cap is a launch gate.

**Contained, understood, fixed: GA confidence holds with one gate**

**What this means for the Executive sponsor**

A deliverability issue in Sprint 12 briefly sent some merchant campaigns to spam; it was caused by an internal control gap (send volume outran our email warm-up), it self-recovered, and there was no data loss or compliance issue [fictional]. Root cause is understood and three fixes are scoped. The one decision for you is to treat the send-rate cap as a hard launch gate for the 2026-07-20 GA, since the same failure mode would otherwise recur when many merchants activate at once. With that gate in place, GA confidence holds. Confirm both.

## Translations applied (internal)

- "send volume ran ahead of the domain warm-up ramp" kept precise for Engineering; rendered as "send volume briefly ran ahead of our email warm-up" for CS/Support and "internal control gap" for Executive.
- "warm-up-aware send-rate cap" kept as the build item for Engineering; rendered as "a hard launch gate" for Executive (decision framing rather than implementation).
- "inbox-placement / reputation alert" kept for Engineering only; not surfaced to CS/Support or Executive (below their decision).
- "no data loss, no compliance issue" surfaced to CS/Support and Executive as reassurance; Engineering gets the root cause instead.

**Flagged but kept** (may need review):

- "erodes IP reputation cumulatively and is slow to repair" (M8) - kept in the master and folded into the Engineering recurrence framing, but not stated plainly to the Executive; confirm leadership understands a repeat is costlier than a one-off, since that is the reason the cap is a gate and not a nice-to-have.
