Start Making Money Today, Not "Someday"
Stuck staring at a blank screen, wondering how to start building your product? Here's a secret: you don't need to write a single line of UI code to get your first paying customers. While others spend months perfecting their interfaces, you could be getting real feedback and revenue this week.
Real Success Stories
Superhuman didn't start with their polished interface. They began with personalized emails and calendar invites. Each new user got white-glove service via email, helping Superhuman understand exactly what users needed before building their now-famous UI. Today, they're valued at over $750M.
A more relatable example: Sarah, an indie hacker, started her content calendar tool by manually sending spreadsheets via email. Within two weeks, she had 3 paying customers at $29/month each. No fancy UI, just solving real problems through email.
Picture This: Your First Week
Monday: Set up your dedicated email address
Wednesday: Help your first customer through email
Friday: Receive your first payment
All without touching a UI framework or design tool.
Why Start With Email?
Building a product traditionally means spending months on user interfaces, only to find out nobody wants your solution. Email-first development turns this approach on its head. By starting with email interactions, you can validate your idea faster and cheaper than ever before.
The Power of Email-First Development
Instead of building complex interfaces, start by handling user interactions through email. This approach, similar to using Google Sheets as an MVP, lets you focus on solving real problems rather than perfecting pixels.
Getting Started
1. Set up a simple email address for your service
2. Create email templates for common interactions
3. Handle requests manually at first
4. Document patterns in user requests
Benefits of Email-First
- Faster launch time
- Direct user feedback
- Lower development costs
- Natural progression to automation
Real-World Success Pattern
Many successful products started as email-based services. Consider how getting your first ten customers becomes easier when you can iterate quickly based on email interactions.
When to Add a UI
Only build a user interface when:
1. You have clear patterns in user requests
2. Manual email handling becomes overwhelming
3. Users specifically request self-service options
Measuring Success
Track these metrics:
- Email response time
- User satisfaction
- Request patterns
- Conversion rates
Implementation Tips
Start with a simple process:
1. Create email templates
2. Set up tracking systems
3. Document common requests
4. Build automation gradually
Scaling Considerations
As your service grows, consider implementing:
- Automated responses
- Email parsing systems
- Basic workflow automation
This approach aligns well with implementing activity-based growth triggers.
Extra Tip
Create a shared email inbox where team members can see all customer interactions. This creates a valuable knowledge base for future development.
Recommendations for Success
Based on successful email-first products, here are key recommendations:
Start Small, Think Big
Begin with manual email processing but document everything for future automation. This approach mirrors successful minimum viable processes.
Focus on Response Speed
Quick email responses create the illusion of automation while building user trust. Consider implementing real-time response tracking.
Document Everything
Create templates for common responses and track user interaction patterns. This documentation becomes invaluable when building your UI later.
Build Community Through Email
Use email interactions to build a community around your product, similar to creating a developer community.
Automation Transition Guide
When moving from manual to automated processes:
1. Identify repetitive patterns in email interactions
2. Create simple automation rules
3. Test automation with a subset of users
4. Scale gradually while maintaining quality
Email-First Analytics Framework
Track these key metrics:
- Time to first response
- Resolution time
- User satisfaction scores
- Common request patterns
This framework aligns with building custom analytics systems.
Scaling Email Operations
As your user base grows:
1. Implement email parsing systems
2. Create automated workflows
3. Build template libraries
4. Consider partial UI implementation

Copy-Paste Email Templates
Here are three templates that have worked for real indie hackers:
Welcome Email Template
Subject: Welcome to [Product] - Let's Get Started Hi [Name], Thanks for trying [Product]! I'm [Your Name], and I'll be personally helping you [achieve main benefit]. To get started, just reply to this email with: 1. What you're trying to accomplish 2. Your biggest challenge with [problem area] I'll get back to you within 2 hours with a personalized solution. Best, [Your Name]
Solution Delivery Template
Subject: Your [Product] Solution is Ready Hi [Name], Based on what you shared, I've prepared [specific solution] for you. Here's how to use it: 1. [Simple step one] 2. [Simple step two] 3. [Simple step three] Need any adjustments? Just reply to this email. Best, [Your Name]
Follow-up Success Check Template
Subject: How's [Product] working for you? Hi [Name], Just checking in to see how [specific solution] is working for you. What's one thing we could improve to make it even better for your needs? Best, [Your Name]
When to Switch to a UI: The Decision Tree
Only build a UI when you can answer "yes" to at least two:
☐ Are you spending more than 4 hours per day on manual email processing?
☐ Have you seen the same request pattern more than 20 times?
☐ Are users explicitly asking for self-service options?
☐ Is your response time exceeding 2 hours consistently?
☐ Do you have more than 50 active users?
24-Hour Launch Checklist
Morning:
☐ Set up dedicated email address
☐ Create welcome email template
☐ Write solution delivery template
Afternoon:
☐ Set up payment link (Stripe/PayPal)
☐ Create quick tracking spreadsheet
☐ Write follow-up template
Evening:
☐ Share on 2-3 relevant communities
☐ DM 5 potential users
☐ Set up email notifications
From the Trenches: Indie Hacker Insights
Recent successes from the email-first approach:
"I spent 6 months building a UI no one wanted. Then I scrapped it all and started with just email. Had my first paying customer in 9 days." - Mike, Analytics Tool Founder
"Email-first let me validate my idea with real payments before writing a single line of UI code. Now we're at $3K MRR and building the UI based on actual user needs." - Lisa, SaaS Founder
The Hidden Advantage
Every email interaction is a gold mine of product research. You're not just providing service - you're building a blueprint for your eventual UI, informed by real user needs and validated by real payments.

Pro Tip: The Rule of 3x
Before automating any process, make sure you've done it manually at least three times and documented each step. This ensures you're automating the right things in the right way.
Start With Documentation
Create a simple system to document every support interaction. Use minimum viable processes to ensure consistency without overwhelming your team.
Build Support-Development Bridges
Set up regular meetings between support and development teams. Share support insights using customized dashboards to keep everyone aligned.
Test Solutions Quickly
Use feature flags to test solutions with small user groups before full rollout. This reduces risk and accelerates learning.
Measure Impact
Track how your solutions affect support volume and user satisfaction. Implement customer health scoring to measure improvement.
