August 25, 2026 # We’re building MailerMine β€” email infrastructure for indie hackers & SaaS founders

Hey everyone πŸ‘‹

I’m building MailerMine, a developer-first email infrastructure platform for SaaS products, startups, and indie hackers.

The idea came from a problem I kept running into while building SaaS products:

Email looks simple until you need to run it in production.

Sending the first email is easy.

Then you need to deal with:

  • Domain verification

  • SPF, DKIM & DMARC

  • API integration

  • Queues

  • Delivery tracking

  • Bounces and failures

  • Webhooks

  • Email logs

  • Analytics

  • Provider-specific APIs

  • And eventually, the cost of sending thousands or millions of emails

I wanted something that felt much simpler from a developer's perspective.

So I started building MailerMine.

What MailerMine does

MailerMine gives you a simple API and dashboard for managing application email.

You can:

πŸ“§ Send transactional emails
πŸ“Š Track delivery and email activity
🌐 Connect your own domains
πŸ”‘ Manage API keys
πŸͺ Work with webhooks and events
πŸ“ˆ Monitor your email infrastructure
πŸ“£ Build marketing email workflows

The goal is:

Connect your domain β†’ get an API key β†’ make an API request β†’ start sending.

Why another email platform?

There are already great products in this space β€” Resend, Postmark, Mailgun, SendGrid, SES, and others.

We're not trying to pretend they don't exist.

We're trying to build something from the perspective of a small SaaS team or indie hacker who wants:

  • A straightforward developer experience

  • Simple APIs

  • Easy setup

  • Useful email observability

  • Transparent pricing

  • Infrastructure that doesn't become another headache

We're starting with email, but the long-term vision is much bigger.

3,000 emails/month free

We're currently offering 3,000 emails every month for free so developers can actually build and test with MailerMine before committing to another monthly bill.

We're also keeping our paid plans focused on being affordable for startups and indie hackers.

We're live πŸŽ‰

MailerMine is now live and we're actively looking for our first group of developers and founders to use it.

I'd love to hear from the Indie Hackers community:

What email provider are you currently using for your SaaS?

And more importantly:

What's the one thing you hate about it?

API?
Pricing?
Deliverability?
Domain setup?
Debugging failed emails?
Analytics?

Tell me what you're using and what frustrates you about it.

That's exactly the kind of feedback I want to use to make MailerMine better.

    The interesting part is keeping the core setup simple despite how messy email infrastructure becomes in production. The 3,000-email free tier also makes it much easier for a developer to test the full workflow before committing to another provider.

        Totally agree. The simplicity of the setup is probably what makes the free tier useful for actually testing the whole workflow.

Email is still one of the most important communication channels for software products, but sending email reliably is surprisingly complicated.
