BlastPad — Twilio SMS Campaign Manager With Better UX Than Twilio
Twilio's native interface was designed by engineers for engineers, not for the small business owner sending 500 promo texts. BlastPad wraps Twilio's API in a dead-simple campaign manager that any non-technical user can operate in under 5 minutes.

Small business owners are hiring developers on gig platforms just to set up basic bulk SMS sending via Twilio, paying $20/hr for a one-time task that should be a self-serve product.
What is it?
The r/forhire market is littered with $20/hr gigs just to set up basic Twilio bulk SMS — that's not a consulting opportunity, that's a product gap. BlastPad gives SMBs a visual contact list uploader, campaign scheduler, opt-out compliance layer, and delivery analytics without touching a single API key. Bring your own Twilio credentials or pay $29/month for hosted credits. The tool handles list segmentation, link tracking, and reply threading so you stop paying a developer every time you want to run a flash sale text. Buildable because Twilio REST API is 15 years stable, Next.js handles the UI trivially, and the entire auth and billing stack runs on Supabase plus Stripe.
Why now?
June 2026 vibe-coding wave means any non-technical founder can now build a Twilio wrapper in a weekend — and the r/forhire $20/hr SMS setup gig market proves the product gap is real and recurring.
- ▸CSV contact list upload with dedup and opt-out scrubbing (Papaparse in browser)
- ▸Visual campaign scheduler with send-time optimization per timezone
- ▸Real-time delivery and click-through dashboard (Twilio webhooks to Supabase)
- ▸One-click TCPA-compliant opt-out footer auto-appended to every message
Target Audience
SMB owners, local service businesses, e-commerce stores — estimated 2M+ US businesses currently using or needing bulk SMS.
Example Use Case
A car wash owner uploads 800 customer numbers from a CSV, schedules a Friday promo blast, BlastPad sends via their Twilio account, and 60 customers redeem the offer — all without touching code.
User Stories
- ▸As a local restaurant owner, I want to upload my customer CSV and send a promo blast in under 5 minutes, so that I fill empty tables on slow nights without hiring a developer.
- ▸As a small e-commerce seller, I want to schedule SMS campaigns in advance, so that I can run Black Friday promotions without staying up to hit send manually.
- ▸As a marketing freelancer, I want to manage SMS campaigns for multiple clients under one login, so that I can charge a monthly retainer instead of hourly setup fees.
Done When
- ✓CSV Upload: done when user drags a 500-row CSV and sees deduplicated contact count with opt-out rows flagged before confirming import.
- ✓Campaign Send: done when user hits Send and sees a live delivery counter increment as Twilio webhooks arrive — no page refresh needed.
- ✓Payment: done when Stripe Checkout completes and user is immediately redirected to dashboard with Pro badge visible.
- ✓Opt-out compliance: done when any inbound STOP reply automatically marks contact as opted-out and excludes them from all future campaigns.
Is it worth building?
$29/month x 50 users = $1,450 MRR at month 3. $49/month x 200 users = $9,800 MRR at month 8. Credit top-ups add 20% on top.
Unit Economics
CAC: $15 via Reddit DMs and cold outreach. LTV: $522 (18 months at $29/month). Payback: 0.5 months. Gross margin: 78% after Twilio passthrough.
Business Model
SaaS subscription + SMS credit top-ups
Monetization Path
Free tier: 100 SMS/month. Pro: $29/month for 2,000 SMS. Business: $79/month for 10,000 SMS. Overage billed at $0.015/message.
Revenue Timeline
First dollar: week 3 via first paid upgrade. $1k MRR: month 3. $5k MRR: month 9.
Estimated Monthly Cost
Vercel: $20, Supabase: $25, Resend: $10, Stripe fees: ~$20. Total: ~$75/month at launch.
Profit Potential
Full-time viable at $5k–$12k MRR with credit margin on top.
Scalability
High — add MMS support, two-way conversation threading, WhatsApp via Twilio, and agency white-label.
Success Metrics
Week 2: 10 beta users sending live campaigns. Month 2: 40 paid subscribers. Month 3: less than 8% churn.
Launch & Validation Plan
Post in r/smallbusiness and r/entrepreneur asking who manages SMS lists manually — DM 15 responders with a Loom demo before writing code.
Customer Acquisition Strategy
First customer: DM 20 r/forhire posters requesting SMS setup help, offer 3 months free in exchange for a testimonial. Ongoing: SEO targeting 'bulk SMS tool for small business', ProductHunt launch, Facebook Groups for local business owners.
What's the competition?
Competition Level
Medium
Similar Products
SimpleTexting ($29/month but no BYOK), EZTexting (expensive for SMBs), Twilio native (no campaign UX) — gap is BYOK Twilio with non-technical UI.
Competitive Advantage
10x simpler onboarding than Twilio native, cheaper than EZTexting or SimpleTexting, BYOK Twilio option keeps costs transparent.
Regulatory Risks
TCPA compliance required for US SMS — opt-out handling is mandatory. A2P 10DLC registration required for bulk sending. GDPR for EU contact lists.
What's the roadmap?
Feature Roadmap
V1 (launch): CSV upload, campaign scheduler, Twilio send, delivery dashboard. V2 (month 2-3): contact segmentation, link click tracking, opt-out automation. V3 (month 4+): white-label, agency multi-client, two-way reply threading.
Milestone Plan
Phase 1 (Week 1-2): schema, CSV upload, Twilio send endpoint, delivery webhook — done when first real message sends. Phase 2 (Week 3-4): Stripe billing, dashboard, scheduling — done when first paid user upgrades. Phase 3 (Month 2): contact segmentation and link tracking live with 20 paying users.
How do you build it?
Tech Stack
Next.js, Twilio REST API, Supabase, Stripe, Resend — build with Cursor for API routes, v0 for campaign UI components, Lovable for onboarding flow.
Suggested Frameworks
Twilio Node.js SDK, Supabase JS, React Hook Form
Time to Ship
2 weeks
Required Skills
Twilio API, Next.js API routes, Stripe billing, Supabase RLS.
Resources
Twilio docs, Supabase quickstart, Stripe billing docs, Next.js app router docs.
MVP Scope
app/page.tsx (landing), app/dashboard/page.tsx (campaign list), app/dashboard/new/page.tsx (campaign builder), app/api/send/route.ts (Twilio send handler), app/api/webhooks/twilio/route.ts (delivery status), lib/db/schema.ts (campaigns, contacts, messages), components/ContactUpload.tsx (CSV parser UI), components/CampaignCard.tsx, seed.ts (demo campaign with 10 contacts), .env.example.
Core User Journey
Sign up -> connect Twilio credentials -> upload CSV -> schedule campaign -> see delivery report in 10 minutes.
Architecture Pattern
User uploads CSV -> Supabase storage -> campaign created in Postgres -> scheduled job triggers Twilio API -> delivery webhooks update message status -> dashboard reads Postgres.
Data Model
User has many Campaigns. Campaign has many Contacts. Campaign has many Messages. Message has one DeliveryStatus updated via webhook.
Integration Points
Twilio for SMS sending and delivery webhooks, Stripe for subscription billing, Supabase for database and auth, Resend for transactional email, Vercel for hosting.
V1 Scope Boundaries
V1 excludes: two-way SMS conversations, MMS/media sending, WhatsApp, team accounts, white-label, custom sending phone number pools.
Success Definition
A non-technical SMB owner finds BlastPad via search, uploads a contact list, schedules a campaign, and renews month two without contacting support.
Challenges
Twilio A2P 10DLC registration is a real compliance hurdle for US SMS — must guide users through brand registration or the messages get filtered.
Avoid These Pitfalls
Do not skip A2P 10DLC guidance — unregistered numbers get filtered and users blame your product. Do not build two-way reply threading in V1, it triples complexity. Finding first 10 paying customers takes longer than the build — budget 3x time for outreach.
Security Requirements
Supabase Auth with Google OAuth. RLS on all user tables. Twilio credentials stored encrypted in Supabase Vault. Rate limiting 50 req/min per user via Next.js middleware. GDPR deletion endpoint required.
Infrastructure Plan
Vercel for Next.js hosting, Supabase for Postgres and auth, Supabase Storage for CSV uploads, GitHub Actions for CI, Sentry for error tracking — total infra under $75/month.
Performance Targets
100 DAU at launch, 500 req/day. API send endpoint under 800ms. Dashboard page load under 2s. Twilio webhook processing under 200ms.

First Run Experience
On first run: demo campaign pre-loaded with 10 sample contacts and a fake delivery report. User can immediately preview the campaign builder and delivery dashboard with real-looking data. No Twilio credentials required to explore UI — connect keys only when ready to send.
How to build it, step by step
1. Define schema in lib/db/schema.ts: campaigns, contacts, messages, delivery_events tables. 2. Run npx create-next-app with TypeScript and Tailwind. 3. Set up Supabase project, run schema migrations, enable RLS. 4. Build CSV upload component with Papaparse parsing and dedup logic. 5. Create campaign builder form with scheduling UI using react-hook-form. 6. Wire app/api/send/route.ts to Twilio Node SDK to batch-send messages. 7. Set up Twilio webhook endpoint to receive delivery status callbacks and update Supabase. 8. Build delivery dashboard with campaign stats queried from Supabase. 9. Add Stripe billing with two plans via Stripe Checkout and webhook to update user tier. 10. Verify: create account, upload 5-contact CSV, schedule a campaign, confirm messages sent and delivery status updates appear in dashboard.
