Next.js SaaS starter with Mailgun
Password resets, verification, and magic links in Next.js need more than a send API call. Mailgun is wired to auth flows with production-ready templates and provider swap support.
The problem
Password resets and magic links through Mailgun 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 Mailgun 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
- Mailgun for verification and reset emails
- Templates tied to auth and account flows
- Swap to Resend, Postmark, or SendGrid later
How teams ship with this kit
- 1
Clone and configure
Add your Mailgun 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 Mailgun?
No. The Next.js kit is a complete SaaS foundation. Mailgun 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 Mailgun guides for Astro and SvelteKit too.
