Case Study: Migrating a Marketing Stack to Free Cloud Tools — Savings & Lessons

Hook: Your marketing stack is bleeding cash — here's a real migration that stopped it

Teams I work with routinely tell me the same story: dozens of marketing subscriptions, low usage, and rising bills. If you're a developer or IT lead asked to justify the stack, this case study gives a concrete playbook: which paid components we replaced with free cloud tools, how long the migration actually took, the measurable savings, and the operational tradeoffs you should expect in 2026.

Executive summary — what we did and why it mattered

Company profile: Mid-size B2B SaaS (marketing team of 6, product-led growth). Monthly paid marketing & analytics spend before migration: $2,450. After moving to free tools and self-service cloud tiers: $210/month (mostly incidental cloud costs). Annualized first-year savings: ~$25,680 including migration engineering time.

Scope: Replace non-core paid marketing SaaS used for landing pages, forms, email capture, analytics, image CDN, and lightweight CRM workflows. Preserve data ownership, deliverability, and conversion tracking while minimizing new operational burden.

Why this matters in 2026

Late 2025 and early 2026 accelerated two trends that made this migration feasible and sensible:

Free and developer-tier cloud offerings matured — systems like Cloudflare Pages, GitHub Pages, Vercel Hobby, and Supabase free tiers offer reliable infrastructure for production lightweight workloads.
Privacy and discoverability shifts (social search and AI summarization) increased demand for first-party data and self-hosted analytics — aligning with free/self-hosted tools that avoid third-party tracking.

At the same time, vendors continued to introduce feature-gated paid tiers. The tradeoff is clear: you can eliminate recurring SaaS cost, but you must accept increased engineering ownership.

Original paid stack (baseline)

Landing pages / A/B testing: Unbounce — $400/mo
Marketing automation / email campaigns: HubSpot Marketing Hub — $800/mo
Transactional email: SendGrid — $200/mo
Analytics / product events: Mixpanel — $250/mo
CDN/image transforms: Cloudinary paid plan — $150/mo
Tag management / routing: Segment (now Twilio Segment) — $300/mo
Forms: Typeform Pro — $50/mo
Misc / backups / small services: $0-$300 depending on month

Free-cloud replacements we chose

We prioritized replacements that required minimal day-to-day maintenance, complemented developer workflows, and gave us clear rollback paths.

Landing pages & static sites: Cloudflare Pages / GitHub Pages (free) + Netlify functions where needed.
Forms: Formspree free tier for serverless form endpoints, or direct POST to a Supabase function for full control.
Analytics: Umami (self-hosted on a free cloud tier) for privacy-friendly, light-weight analytics; Google Analytics 4 remained as a secondary feed for enterprise reporting needs.
Marketing automation / CRM: HubSpot CRM free + Airtable free for campaign tracking; lightweight automation via GitHub Actions and Azure Logic Apps free-tier connectors for small volumes.
Transactional email: Amazon SES (low cost / free tier for EC2), but for strict free we routed low-volume transactional email through Gmail API for dev/proof-of-concept and Postmark for higher reliability (small monthly cost added where needed).
CDN & image transforms: Cloudflare Images and Cloudflare Workers (free tier) + client-side transforms where acceptable.
Event routing: Direct instrumentation to Postgres (Supabase free tier) and lightweight pub/sub using Cloudflare Workers KV for ephemeral routing — eliminating Segment routing costs.

The migration timeline — realistic week-by-week plan

We ran this as a focused 10-week project with three small cross-functional teams: infra (2 devs), data (1 data engineer), and marketing ops (1 product/marketing lead). The timeline below is the template you can reuse.

Week 0 — Project kickoff & audit

Inventory active SaaS: identify accounts, owners, billing cycles. Use the 80/20 rule: stop anything with <20% monthly usage.
Measure current spend and define KPIs: cost, MQL conversion, email deliverability, page speed.

Week 1–2 — Plan exports & parallel infra

Export contact lists, form submissions, and event logs from paid services into CSV / JSON.
Provision replacements: Cloudflare Pages site repo, Supabase project (free tier), and a small VM or function for Umami.
