Next.js SaaS starter with Postmark
Password resets, verification, and magic links in Next.js need more than a send API call. Postmark is wired to auth flows with production-ready templates and provider swap support.
The problem
Password resets and magic links through Postmark in Next.js are easy in a tutorial and surprisingly painful when deliverability, templates, and auth state all need to match.
Building it yourself
Scaffold Next.js, find a Postmark tutorial, wire env vars, fix auth sessions, then repeat for billing and email. Most teams lose weeks before the stack deploys cleanly or handles real users.
What you get out of the box
- Postmark for password reset and verification email
- High-deliverability transactional templates ready
- Swap to Resend, SendGrid, or Mailgun via config
How teams ship with this kit
- 1
Clone and configure
Add your Postmark keys and provider settings to the included env template. The Next.js app boots with the integration active.
- 2
Customize product flows
Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.
- 3
Deploy with included configs
Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.
- 4
Swap providers later
Client wants a different payment processor or database? Change adapters through config instead of rewriting your Next.js app.
Also ships with every Next.js kit
- Password reset flow
- Magic links
- Auth session cookies
- Resend-to-Postmark swap
Common questions
Is this only about Postmark?
No. The Next.js kit is a complete SaaS foundation. Postmark ships alongside auth, billing, email, analytics, storage, and deployment so you are not assembling the stack from scattered tutorials.
Can I see it working before I buy?
Yes. The live demo runs the same Next.js starter with real auth and billing flows. Open the demo, click through signup and checkout, then compare with your timeline.
What if I need Astro or SvelteKit instead?
LaunchFast ships the same integration surface in all three frameworks. Related links on this page point to the Postmark guides for Astro and SvelteKit too.
