SaaS Email Deliverability Web App
Budget: ₹12,500 – ₹37,500 INR
Objective
Build a web-based SaaS platform that helps users create and manage pre-warmed mailboxes with automated domain setup (SPF, DKIM, DMARC) and integrations for cold-email tools like Lemlist, Instantly, and Reply.io.
Core Features (MVP Scope)
1. User Dashboard (Frontend)
Built with Next.js (React + Tailwind CSS).
Secure login / signup via email + password + JWT session.
Dashboard sections:
Mailboxes: Add, view, or delete mailboxes.
Domains: Add or connect custom domains.
DNS Setup: Show generated DNS records for SPF, DKIM, DMARC.
Warmup Status: Progress bar and daily activity chart.
Integrations: Connect Lemlist, Instantly, Reply, etc.
Billing: Stripe checkout & subscription status.
Support / Docs: Static pages with FAQ.
2. Backend (API Layer)
Stack: Node.js (Express) or Python (FastAPI).
Database: PostgreSQL (Supabase / RDS).
Authentication: JWT-based.
Core Endpoints:
POST /api/domains – Add or register new domain.
GET /api/domains/:id/records – Retrieve SPF/DKIM/DMARC entries.
POST /api/mailboxes – Provision mailbox (Google/Microsoft).
GET /api/mailboxes/:id/status – Return warmup & health metrics.
POST /api/integrations/:provider – Connect outreach tool.
GET /api/metrics/:mailboxId – Return inbox rate, bounces, spam, etc.
POST /api/payment/webhook – Handle Stripe events.
3. DNS Automation
Auto-generate records:
SPF → v=spf1 include:_spf.google.com -all
DKIM → unique key per mailbox.
DMARC → v=DMARC1; p=none; rua=mailto:dmarc@domaindotcom.
Use APIs (Cloudflare, Google Cloud DNS, or Route53) for automated record setup.
Verify each DNS record before enabling sending.
4. Email Warmup Engine
Internal scheduler that sends small batches of emails between “warmup pool” mailboxes.
Simulate replies, opens, and clicks to build trust.
Store warmup logs and show a simple progress metric.
Respect rate limits to avoid blacklisting.
5. Integrations
REST/webhook connectors for:
Instantly
Lemlist
Reply.io
Ability to push new warmed mailboxes to those platforms via API key or OAuth.
6. Admin Panel (Internal Use)
View all users, mailboxes, domains.
Suspend or throttle users if bounce rate is high.
View API logs, DNS verification results, and warmup queue health.
7. Billing & Subscription
Stripe integration (monthly plans).
Plans:
Starter – 5 mailboxes
Growth – 25 mailboxes
Agency – 100 mailboxes
Automatic mailbox deactivation on payment failure.
8. Infrastructure & Deployment
Hosting: AWS (EC2 + RDS) or GCP (Compute + Cloud SQL).
CI/CD via GitHub Actions.
Monitoring: UptimeRobot or New Relic.
Email infrastructure: use Google Workspace API / Microsoft Graph API for provisioning.
Technical Requirements
Clean, modular code with API documentation (Swagger/OpenAPI).
Reusable components, scalable architecture.
Deployment instructions (Docker preferred).
Security: input validation, rate limiting, and HTTPS everywhere.
