Show HN: Jade Email. Unlimited emails for your domain plus AI Agent support

Hacker News - Tue, 09/22/2026 - 5:46pm

Hello HN!

I've spent the last 4 years building Jade.email, an email service, and it's now better than any email service I've used. I'm incredibly proud of it and have a small group of paying customers already.

It's similar to SimpleLogin where you get unlimited emails for your domain on the fly. The key difference is that it's not a relay that just forwards to your existing email. The whole product is designed around this concept, and you get actual mailboxes that you can connect to with IMAP, have different rules for, view separately, etc.

The rules are really powerful as well, and can target different inboxes. I have any emails that have login links or verification codes notify me and self delete after 7 days. I have rules that automatically mark an email as read if it has any "list-unsubscribe" headers and then automatically try unsubscribing.

The best part though is you can connect any agent to it (except Gemini because Google is the worst) and it can not only do the normal email stuff, but it can also manage your rules too. So if I have a new inbox I'll ask Claude or ChatGPT to analyze that inbox and suggest rules or categorization/etc and it just works.

It's also an approved plugin on the ChatGPT plugin marketplace so I'm seeing AI first sign up traffic from people who have never even visited the website.

You can sign up for free and receive email at a domain I generate for you if you want to try it out. If anyone is interested in trying out the more full version where you have your own domain and send email, I'm also happy to send you a promo code for the first month free.

Also happy to answer any questions!

Show HN: NetM8 OS

Hacker News - Tue, 09/22/2026 - 5:03pm

First post on HN. I wanted to make my marketing/digital consultancy site a bit fun and different by recreating an OS. Click around, have fun and break things (although go easy on the 'concierge' which is on a free Workers AI plan pls)! I'm a solo marketing and communications person and have self taught web dev-ish over the past three years and I'm keen to learn and improve so do your worst
