Bye bye Beehiiv 👋 I vibe-coded my own newsletter platform: 📧 Campaign management w/ editor 🖥️ Web archives (https://t.co/pypYdNhdlZ) 🔗 API support 🫧 List cleanup, deliverability reports It took a few prompts with Opus 5.5. I left Beehiiv because they raised prices for the 3rd time in 2 years. - My first yearly bill was $1,000. - My future bill would have been $4,000. Now I'm using AWS SES + MongoDB, and I will pay less than $300/year. Newsletter platforms charge per subscriber, when in fact the real cost is the number of emails sent. Subscribers will naturally become inactive, so you end up paying more for something that hurts your deliverability (sending to dormant subscribers = spam trap). So I've set a cleanup cron job for my newsletter alternative. It marks inactive subs as dormant, sends one last re-engaging email, and stops emailing them. Money saved. Deliverability increased. I also gain a priceless feature: Freedom. I can change the UI, add features, connect all my apps - anything is possible with just a prompt. I'm replacing Resend next. I love it, but it's very expensive ($400/mo)

@leodev
Resend started as a frustration. As an indie hacker, working nights and weekends, I felt like every email service was built for someone else. So I decided to create my own. Today @marclou runs 33 startups solo on it. I know Resend is not for everyone (and that's okay), but it feels nice to be able to build products for other indie hackers.

Today, we're shipping the new Resend email editor, extended by AI. What I love about this is that you can BYOA (Bring Your Own Agent). There's a built-in LLM that can help you draft an email based on an URL. But you can just MCP into the editor too.
