Flowmails | CF native domain email box

What it does

Self-hosted custom-domain email on your own Cloudflare account. Inbox & outbox in your D1, REST API + webhooks, AI draft coming Q3 2026. No SMTP.

Send and receive email with a self-hosted email API on Cloudflare — inbox & outbox in your own D1, REST + webhooks, no SMTP. Free tier available.

Flowmails is a self-hosted email API that runs entirely on Cloudflare. Send and receive email through a simple REST API, with your inbox and outbox stored in your own D1 database — no SMTP server to manage, no shared inbox, and webhooks for every event. Inbox and outbox live in your own D1, attachments in your R2, and outbound sends go through Cloudflare Email Services — no SMTP relay, no shared multi-tenant table, no third-party lock-in. The default route table catches every inbound; route templates fan out to Slack, your CRM, or any Workers webhook; AI draft + reply (Q3 2026) lives one click away from any inbound. › [runtime] flowmails-worker connected flowmails.net → D1 (WEUR) › ›…from flowmails.net

  DIY Disposable Email Service Using Cloudflare2023 · github.com · ▲8

  I recently discovered Cloudflare Email Routing. It's a super sweet feature within Cloudflare for creating disposable emails. Basically, if you have a domain connected to Cloudflare - you can create email addresses like "[email protected]" that can forward emails to your primary inbox (Gmail, Outlook, Apple Mail, etc.). This is great since you'll never need to share your real email address when signing up for new online services again. It will help you keep your primary inbox free from spam and promotional junk! However, managing my disposable emails using Cloudflare's UI is not…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I replaced a $120k bowling center system with $1,600 in ESP32s▲2,935

  I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

  Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)▲1,033

  Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

  Getting GLM 5.2 running on my slow computer▲937

  A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…

  OpenSEO▲928

  Hello! For the last 2 months, I've been building OpenSEO. It's a user friendly UI wrapping the DataForSEO API which has high quality SEO data for keywords, backlinks, AI SEO and competitor research. Instead of paying $100+ per month, you buy DataForSEO credits and pay only for usage. The coolest thing about the project so far has been hearing about what people are building on top of it. People are using coding agents to quickly integrate with Google Search Console, Google Ads and building their own AI SEO and reporting features. Many were already building their own custom solutions around…
