CredMail.com - Email Deliverability Platform

About this project

CredMail.com gives any email domain a single trust score. Enter a domain and it checks SPF, DKIM, DMARC, MX, 107 blacklists, BIMI, MTA-STS and TLS-RPT, then explains what's wrong in plain language with AI-generated fix steps. Every check creates a shareable public report, so agencies and consultants can send clients proof of the problem and the fix. Who it's for: cold-email agencies, deliverability consultants, inbox and warm-up providers, and SaaS founders whose emails land in spam. It's also a strong free top-of-funnel tool for an email infrastructure, warm-up or verification company: someone sees a weak score, then buys your fix. What's built: • Live app on Next.js, hosted on Vercel • Clerk sign-in and Stripe billing, already wired up • Plans: Free (3 checks a month), Growth $9, Pro $29, Agency $79 • Paid email verification through Bouncer • Public shareable report pages • Exact-match .com domain Stats: 3 months old, 2 users, $0 revenue. It's fully built but not marketed, so it's priced to sell. Included: domain, codebase, Stripe and Clerk setup, and a handover call. Why I'm selling: I'm focusing on consulting and want CredMail with someone who can put distribution behind it.

Original vision

Email deliverability is confusing. Most founders don't know what SPF, DKIM or DMARC mean until their emails start landing in spam. I wanted a simple trust score for an email domain: one number, a clear list of what's broken, and exact steps to fix it, without needing a deliverability expert. The shareable report was meant to make CredMail spread on its own, with agencies sending it to clients and founders sending it to their dev. The plan was a free check that converts into paid monitoring.

What's included

Everything that comes with the listing on day one.

• Domain name
• GitHub repository
• Source code archive
• Hosting account (Vercel, Netlify, Fly, etc.)
• Database export or transfer
• Stripe account and products
• Customer or user list
• Logo and brand assets
• Marketing or landing page
• Email service account (Resend, Postmark, etc.)
• Social media handles
• Onboarding call with the founder

Why it's available

I built CredMail fast and it works well, but my main focus is my day job and other projects, and I don't have time to market it. It deserves an owner who can put distribution behind it, especially an email tool that already has an audience. It's priced to sell, and I'll do a handover call to get you running.
