## Why We currently rely on Stripe's automated trial-ending email. It misfires: the global "remind 7 days before trial ends" setting lands the reminder on **signup day** for the 7‑day no‑card trial, and the "your card will be charged" copy makes no sense for a trial with no card. This replaces it with our own honest, well‑timed, Twenty‑branded emails. ## 🔒 Safety — these emails are OFF by default Because these reach real customers, the whole feature is gated behind a kill‑switch that **defaults to `false`**: - **`BILLING_REMINDER_EMAILS_ENABLED` (default `false`)** — checked **both** at cron registration **and** on every job run (defense in depth), so the emails can never be sent inadvertently (not on deploy, not in staging, not via a stray trigger). They only go out once an operator explicitly opts in. - Also gated on `IS_BILLING_ENABLED` (cloud‑only; self‑hosters unaffected). - In non‑prod the email driver is typically `logger`, so even if enabled there, nothing is actually sent. A unit test asserts that with the switch off, **zero** emails are produced. ## What it does A daily cron (`0 8 * * *`) sends three honest, Twenty‑branded emails: | Plan | Email | When | |---|---|---| | No‑card trial (7d) | "Add a card to keep your data" | **1 day before** trial ends | | Card‑on‑file trial (30d) | Upcoming‑charge heads‑up (cancel in one click) | **7 days before** first charge | | Yearly subscription | Renewal reminder (no surprise) | **7 days before** each renewal | - **Monthly renewals get no reminder** (avoids noise) — only the first charge and annual renewals do. - Branches no‑card vs with‑card on the customer's payment‑method flag (with a trial‑duration fallback), so someone who adds a card mid‑trial correctly gets the charge heads‑up instead of the add‑a‑card one. - **Idempotent** per `(workspace, boundary date)` via workspace‑level user vars — yearly reminders re‑fire each period, but the daily cron never double‑sends. - Offsets are configurable via new `BILLING_*_REMINDER_DAYS_BEFORE` variables. Also **warms up the tone** of the existing suspended / deleted workspace emails (less robotic, fair, loss‑aversion framing) — these already act as the "come back or lose your data" win‑back, so no extra win‑back email was added. ## Rollout 1. Merge. 2. Disable Stripe's automated trial/renewal customer emails in the Stripe dashboard. 3. Review copy/timing, then set `BILLING_REMINDER_EMAILS_ENABLED=true` to turn the cron on. ## Notes for reviewers - **i18n:** new English strings render via Lingui's msgid fallback; translation catalogs are intentionally **not** included to keep the diff focused (the repo extracts translations via its standard periodic `lingui extract` sync — `main` already carries catalog drift). Diff is 18 code files. - **Recipients:** reminders go to all workspace members, consistent with the existing suspension emails. Happy to scope the charge‑related ones to billing admins if preferred. - **Follow‑ups discussed:** in‑app trial banner, loss‑aversion with real record counts, and failed‑payment dunning are the higher‑leverage conversion levers beyond this. ## Test plan - [x] `typecheck` (twenty-server, twenty-emails) - [x] oxlint type‑aware + oxfmt - [x] Unit tests: no‑card path, with‑card path, idempotency, yearly renewal, billing‑disabled, **kill‑switch off → no send** (6/6 green) - [ ] Manual: set the flag on a staging instance with `logger` driver and confirm the right email is logged at each boundary https://claude.ai/code/session_0147ujzHv1X4vzimf4iGbnT4 --- _Generated by [Claude Code](https://claude.ai/code/session_0147ujzHv1X4vzimf4iGbnT4)_ <!-- This is an auto-generated description by cubic. --> <a href="https://cubic.dev/pr/twentyhq/twenty/pull/22186?utm_source=github" target="_blank" rel="noopener noreferrer" data-no-image-dialog="true"><picture><source media="(prefers-color-scheme: dark)" srcset="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"><source media="(prefers-color-scheme: light)" srcset="https://www.cubic.dev/buttons/review-in-cubic-light.svg"><img alt="Review in cubic" src="https://www.cubic.dev/buttons/review-in-cubic-dark.svg"></picture></a> <!-- End of auto-generated description by cubic. -->

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
