Problem

A workflow author without a verified domain has no sender to pick in an email step, so they cannot build a workflow that emails anyone. This layer offers the sandbox sender in the step's sender picker.

Supersedes PostHog#111695 (left open as the original draft). The template test-send interaction follows in a separate layer.

Stack: layer 6 of 12, stacked on #441. Next: #451.

This fork PR moves to an upstream PostHog/posthog PR after review.

Warning

🟡 Merge risk: medium · two-way door (merge-risk rubric)

• Sender selection affects workflow configuration; the sandbox feature flag limits new selections.
• Save-time restrictions and delivery guards remain enforced by the preceding layers.

Changes

• The "Before you send" check for a cohort no longer counts the sandbox sender as a verified sender. When it is the only sender, the dialog says it only delivers to organization members and offers "Set up email".
• Failed sender loading or sandbox setup keeps both Try again and Connect email sender available.
• Selecting sandbox confirms replacement of multiple senders and names them. Custom From, sender name or Reply-To values also require confirmation.
• Channels keeps the loaded grid after a failed refresh and shows a small stale notice with a retry.
• An initial Channels load failure shows the API error detail.
• Email workflow steps offer the sandbox sender alongside project senders and explain the verified-member restriction.
• Sandbox remains exclusive from sender rotation.
• Transactional email templates list only the project's own senders, not the sandbox sender.
• Channels shows the managed sender separately from user-managed connections and preserves the existing channel catalog.
• Saved sandbox selections keep their restrictions after flag rollback; broadcasts and setup status consider only user-managed senders.
• Provisioning avoids duplicate requests and ignores results from another project; an explicit request retries transient failures.
• Mechanical: sender-picker component extraction, inline type generation, and the missing HogVM AST type export required by master's existing frontend import.

UI walk at fa33d78fb36. Captures from a local preview of the stack tip fa33d78fb36, flag workflows-sandbox-sender, demo data. Flag off is the before. Real SES is unreachable in this preview, so sends stop at the SES call, shown as ECONNREFUSED.

Before (flag off): Channels shows Email as not set up, and there is no sandbox sender.

After (flag on): Channels provisions the sandbox sender and shows it in its own row, with the members-only copy and Add your own sender.

Before (flag off): an email step in a project without senders has nothing to pick.

After (flag on): the picker offers the sandbox sender with a Sandbox tag.

After picking it: the hint says it delivers only to verified members, and Reply-To and the custom sender fields go away.

Narrow (side panel open, about 547px of scene): the picker, hint and menu fit without clipping.

Known follow-up: with a verified own sender, the sandbox row still offers Add your own sender.

Earlier captures. Each caption names the commit it was taken at.

The email step sender picker lists the sandbox sender with a Sandbox tag, and the step says who it delivers to. Taken at 7f003f71b3c in the combined live preview of both stacks.

The Messaging channels page shows the sandbox sender row above the project's own connections. Taken at 7f003f71b3c in the combined live preview of both stacks.

When senders fail to load, the email step keeps Connect email sender next to the error and its Try again. Taken at 2a8c88382f0 in the combined live preview of both stacks.

When a background refresh fails, Channels keeps the loaded grid and shows a small stale notice with Try again. Taken at 2a8c88382f0 in the combined live preview of both stacks.

When the first load fails, Channels shows the API error detail. Both failures were simulated by failing the integrations request in the browser. Taken at 2a8c88382f0 in the combined live preview of both stacks.

With two own senders rotating, the picker warns that choosing the sandbox sender replaces the selection. Taken at 2a8c88382f0 in the combined live preview of both stacks.

Picking the sandbox sender then asks for confirmation and names both senders it replaces. Taken at 2a8c88382f0 in the combined live preview of both stacks.

Known follow-ups (found in the UI walk, not fixed here):

• The Channels sandbox row keeps offering "Add your own sender" after a verified own sender exists.

How did you test this code?

Current evidence, 2026-10-24, head 0cff277a9df.

Owed proofs:

• Live run: rerun at the stack tip 8ac8853cc82, which contains this layer. The stack's cdp-api sent through the workflow test-run endpoint to a local SES fake that records each request. 9 of 9 cases pass. 12 of 13 recorded cases match the run at fa33d78fb36. Case 2c (an unverified member on To) now shows the verify-your-email guidance with reason recipient_unverified, and makes no SES request. For this layer: case 1 sends from a step that selected the sandbox sender. The UI walk shows the picker.
• UI walk: local preview of the stack tip fa33d78fb36, flag workflows-sandbox-sender off (before) and on (after), demo data. The captures sit in Changes, beside the behavior each one shows. Round 4 changes no UI in this layer, so these fa33d78fb36 captures still hold at the round 4 head.

Changes in this layer since the 2026-10-19 heads (restacked onto fork master 448d802: no conflict in this layer):

• Round 1 fixed: the transactional template sender list no longer shows the sandbox row as a normal sender, a list master added since the old base (EmailSenderSummary.test.tsx).
• Round 1 fixed: sender load errors keep the API detail or fall back to copy per surface, so the Channels fallback is reachable again. One sandboxEmailSenderSetupError selector replaces three copies of the rule (integrationsLogic test with and without API detail).
• Round 1 fixed: copy: the audience warning says "verified" again, and a helper replaces the nested ternary for the rotation hint.
• No change in this layer since round 2.
• Final read: GPT-6.1 Sol read the G3 layer range-diffs and found nothing.
• Round 4: no change in this layer.
• Final read 2: GPT-6.1 Sol read the round 4 range-diffs per group and found nothing.

Local gate at the stack tip 8ac8853cc82, shared by every layer

• Python suites for workflows, messaging, CDP validation and integrations: 3007 passed.
• Node CDP messaging, managers, rate limiter, hogflows and cdp-api: 42 suites, 1157 passed.
• Frontend Jest for the 17 changed suites: 292 passed.
• mypy: clean. Node tsc and frontend tsgo: clean.
• ruff, oxfmt, prettier, eslint and oxlint: clean on the 15 files changed in round 4.
• Per-layer suites during the round 4 fold: feat(workflows): restrict sandbox email to verified org members #434 Node 201 passed, feat(workflows): cap sandbox sends and refund ses throttles #441 222, feat(workflows): test templates with the sandbox sender #451 frontend 27, feat(workflows): honor shared sandbox tenant pauses #453 Python 93 and Node 234, feat(workflows): offer a switch from the sandbox sender #456 banner 15.
• Review: round 1, round 2, final read 1 and final read 2 per group. Every finding is fixed or recorded as a follow-up. Both final reads found nothing.

Test seams: real integration-loader and channel-catalogue actions, templater selection, the rendered sender picker and the transactional template sender list.

Test rationale: Existing picker cases cover failed loads, failed setup and explicit 404 retries. The rotation case confirms replacement and names both senders. Rendered picker and catalog cases prove recovery actions, preserved connections and API error detail.

Gaps: real AWS SES delivery and the AWS-side tenant pause (every proof uses a local SES fake or an unreachable SES), clustered Valkey, the production data shape (prod-shape gap until production read access on 2026-11-02), and fork CI, which fails during setup: path selection fails without a GitHub App client ID, and the Security aggregate rejects its fork-skipped path-filter job. Application CI is a verification gap. The UI walk could not create an own sender through the UI, because SES was unreachable; it seeded own senders in the database instead.

Round 3 heads, 2026-10-23. This layer's head: 1ff130bc716. Stack tip fa33d78fb36.

• Live run: run at the stack tip fa33d78fb36, which contains this layer. The stack's cdp-api sent through the workflow test-run endpoint to a local SES fake that records each request. 9 of 9 cases pass, identical to the earlier run. For this layer: case 1 sends from a step that selected the sandbox sender. The UI walk shows the picker.
• Local gate at fa33d78fb36: Python 3007 passed; Node CDP 42 suites, 1157 passed; email service suites at the final heads of feat(workflows): restrict sandbox email to verified org members #434, feat(workflows): cap sandbox sends and refund ses throttles #441, feat(workflows): test templates with the sandbox sender #451 and feat(workflows): honor shared sandbox tenant pauses #453 passed; frontend Jest 17 changed suites, 290 passed; mypy, Node tsc and frontend tsgo clean; ruff, oxfmt, oxlint, prettier and eslint clean on the files changed since round 2. Final read 1 found nothing.

Whole-stack QA swarm, 2026-10-19. Reviewed tip cfee7e148ae. This layer's head: 4964ee37062.

• Live run at b9bd346ed0e (this stack's cdp-api against a local SES fake, workflow test-run endpoint): a sandbox send to a verified member went out from the fixed identity through the sandbox tenant and configuration set. The step's From name, From address and Reply-To were ignored with a log line. A non-member on CC and an unverified member were blocked with the clear message. A paused tenant state skipped sandbox sends while own-sender sends continued.
• Shadow diff: an own-sender send produced the same SES request and the same stored message on master and on this stack.
• Cross-version: a worker on master reports a sandbox send as sent without calling SES. See the deploy order in feat(workflows): provision a managed sandbox email sender #426's merge risk.
• Checks at the tip (Node suites at 1a0fe3663c2; later fixes touch no Node code): Node CDP messaging, members and rate limiter suites (including email-tracking.service.test.ts, which now runs), the cdp-api suite, the Python sandbox, tenant, tier, reputation and validation suites, the frontend Jest suites of this stack, ruff, and the strict pre-push preflight: pass.
• Fixed in this layer: the message audience sender check ignores the sandbox row and explains a sandbox-only project. New parameterized cases for broadcast and workflow destinations failed before the fix.
• Gaps: real AWS SES delivery, clustered Valkey, and the production data shape (no production read access yet). Fork CI still fails during setup.

Rebased onto master 734468db6f9 (2026-10-19), head 1c24925856f.

• Drift: Master added the email media library to emailTemplaterLogic (feature flag and project connects, emailMediaLibraryEnabled, unlayerEditorUser), a scope-shortfall event to integrationsLogic, and new workflow flags in constants.tsx.
• Adapted: The templater keeps master's media library selectors and this layer's supportedFields-based visibleFields and hiddenAdvancedFields. integrationsLogic connects both master's event and this layer's setFeatureFlags. WORKFLOWS_SANDBOX_SENDER keeps alphabetical order.
• This layer: Jest at this layer for the email templater, integrations, and Channels: 11 suites, 154 passed.
• Gaps at modernize time: email-tracking.service.test.ts did not run then. It runs now; see the QA swarm block above. Fork CI still fails during setup, as noted below. Real AWS delivery and clustered Valkey remain unchecked.

✅ Toolbar bundle — eager 2.29 MiB within budget

What the toolbar ships to customer pages, measured from the esbuild output (minified, post-tree-shake). The eager set is the entry plus everything statically imported from it — fetched before any feature runs; deferred chunks load lazily. The eager guardrail is 5.72 MiB. Each output file must also stay below 10 MB, where CloudFront stops compressing it. The module boundary is enforced separately by check-toolbar-graph.
