Email provider configuration

Configure transactional delivery and verify its independent outcome.

Setup and configuration

Before any step, read Before you start and Terminal basics. These instructions assume you opened the full supastack monorepo in VS Code; its root package.json marks the repository root. In pnpm commands, a workspace package is an app or shared-code folder; in the product, a workspace is a team's data container and security boundary. corepack pnpm --filter ... selects one package from the monorepo while commands run from its root. If you opened only a synced mobile or desktop folder, it does not contain the Web backend, Docker setup, or root scripts: run the backend from this monorepo or a reachable hosted server, and use the platform folder's own scripts. An environment variable is a named setting stored in a local .env file or your hosting dashboard; restart the relevant app after changing it, and keep server secrets out of NEXT_PUBLIC_ and EXPO_PUBLIC_ values.

1. Open apps/web/.env.local and set EMAIL_PROVIDER=local for development; EMAIL_FROM is the sender label used by templates.

2. Start the Web app from the repository root with corepack pnpm --filter @supastack/web dev and trigger one sign-in or invite flow with a test address. Expected: the app records a local email outcome without contacting a real provider. Only connect Resend, SES, or another service after its sender domain is verified and test recipients are restricted.

EMAIL_PROVIDER=local keeps deterministic delivery local. For configured production delivery, review the Resend or SES adapter and provide its server credentials. EMAIL_FROM must match the identity verified with the selected provider.

EMAIL_PROVIDER=local
EMAIL_FROM=supastack <[email protected]>
# Production adapter configuration is listed in .env.example.

Commands to copy

Follow the comments to see which folder a command runs in. If two terminals are labeled, open two terminal windows and keep the first command running while you use the second.

corepack pnpm --filter @supastack/web dev

Implementation workflow

Authentication and completion messages use the transactional email boundary. Outreach workflows belong to the consuming product and remain separate. Never reuse this path as an unreviewed bulk messaging subsystem.

Record delivery separately from generation. A model result can be available while its completion message fails. Recovery must inspect delivery state instead of generating the same result again.

Verification and troubleshooting

If no local email appears, check that EMAIL_PROVIDER is set in apps/web/.env.local and restart Web. If a real provider rejects a message, confirm EMAIL_FROM matches a verified sender and inspect the provider's delivery record. A generated AI answer can succeed even when its follow-up email fails; check delivery before running the AI task again.

Verify recipient restrictions, sender identity, and provider errors in a dedicated test environment. A local adapter result is not evidence of real email delivery. The opt-in smoke path restricts recipients through REAL_SMOKE_EMAIL_ALLOWED_DOMAIN.

Frequently asked questions

14 questions

What is supastack?

supastack is a modular foundation for building AI-powered SaaS products. It brings together common infrastructure so you can focus on product-specific features.

Does it support web and mobile?

Yes. supastack includes Next.js and Expo apps as starting points for web and mobile experiences.

What authentication is included?

Better Auth covers email OTP, magic-link, and social sign-in; email/password stays available at the API layer and through the Auth.js credentials engine for products that need it. Personal workspaces are provisioned with the account so product records stay scoped from day one.

How does it support AI?

supastack includes configurable multi-provider AI, usage tracking, budgets, and encrypted bring-your-own-key support.

How are subscriptions handled?

For products built on the kit, Stripe billing, subscriptions, and entitlements form the paid-access foundation. Provider secrets stay server-only.

Where does my product-specific code live?

Product-specific features remain in a separate codebase while the product configures and integrates supastack’s foundation modules.

How does supastack pricing work?

The kit is a one-time purchase with lifetime updates: One Platform at $249 (temporary launch price, $100 off the regular $349) — your pick of Next.js (Web), Expo (iOS & Android), or Tauri (macOS & Windows Desktop) — or the All Platforms Bundle at $499 (temporary launch price, $100 off the regular $599) with every platform and the full monorepo, plus $75 per extra developer seat. No kit subscription. Checkout on this site delivers your license key by email, with repository access via GitHub invite.

How do workspaces scope my data?

User-owned records are scoped by workspaceId. Identity, entitlements, AI usage, billing events, and audit entries stay inside the personal workspace boundary.

How do background jobs work?

Trigger.dev is the explicit job runtime. The JobRunner contract only promises enqueue, status, and cancel—workflow semantics stay Trigger.dev-specific and explicit.

How is email different from outreach?

Transactional email covers product workflows such as completion notices. Cold outreach and campaigns are product concerns outside this kit’s email module.

How do mobile purchases work?

Mobile includes native purchases and restore through RevenueCat, with access verified by your server. Configure the store accounts and complete device testing before release. Web billing remains separate.

Where do AI provider keys live?

Bring-your-own-key credentials are encrypted and stay server-only. Keys are redacted from logs; usage and budgets remain visible at the workspace level.

Which payment methods does checkout accept?

The Stripe-hosted checkout accepts cards and can also offer Alipay and WeChat Pay once those wallets are enabled on the Stripe account — handy for buyers in China. Wallet authorizations confirm asynchronously, so the license page updates as soon as the payment clears.

Can I get a refund?

After you've got access to the repository, supastack is yours forever, so it cannot be refunded. But rest assured, you get the complete source code with lifetime updates to build and ship unlimited products for yourself or clients. You just cannot resell the code or redistribute the repository as a starter kit or template.
