Customer Onboarding Templates

Email Templates for Indie Hackers

You're a team of one. Your emails should work as hard as you do.

Indie hackers have an unfair advantage in email: authenticity. When an email comes from a solo founder, it feels personal - because it is. These templates lean into that advantage while keeping things professional and effective.

Best Practices

Be personal. Your biggest advantage over big companies is authenticity.

Ask for replies. Solo founders who respond to every email build insane loyalty.

Share the journey, not just the product. Building in public creates fans.

Keep it short. Indie audiences respect brevity.

Common Mistakes

Trying to sound like a big company when you're a solo founder.

Not sending emails because your list is 'too small' - 100 engaged subscribers is powerful.

Over-automating and losing the personal touch.

Only emailing when you want something - share value regularly.

Personalization Tips

Your Unfair Advantage Is Authenticity

Big companies can't send emails from the founder. You can. "I built this solo and every user matters" resonates more than any corporate marketing copy. Lean into it.

100 Subscribers Is Enough

Don't wait for 10,000 subscribers to start emailing. 100 people who signed up for your product updates are your most valuable audience. They'll give you feedback, share your product, and become your first customers.

Build in Public Through Email

Share your revenue milestones, feature launches, and even failures. Your audience wants to follow the journey. Every milestone email is a reminder that your product exists and is growing.
