Recivo – Receive Emails Programmatically
Hi HN, these last couple of weeks I've been building 'Recivo', a simple way to receive emails programmatically. There are plenty of API-based services that can be used to send emails, but receiving them is harder. As a Recivo user, you create a new email address which will then immediately be available for receiving emails. A REST `/inbox` endpoint is exposed for retrieving these emails, this includes all data you would expect: subject, content, sender, and most importantly: attachments. You can also get notified of newly received emails using webhooks. The main use-cases I'm thinking…
In plain words
Recivo is a service that allows developers to receive and process emails programmatically. Users create email addresses that immediately become active for receiving messages, then access emails through a REST API endpoint that includes subject, content, sender details, and attachments. The service also supports webhook notifications for new emails. It is designed for developers building applications that need email input capabilities, such as AI agents triggered by email or document upload flows for SaaS platforms.

Hi HN, these last couple of weeks I've been building 'Recivo', a simple way to receive emails programmatically. There are plenty of API-based services that can be used to send emails, but receiving them is harder. As a Recivo user, you create a new email address which will then immediately be available for receiving emails. A REST `/inbox` endpoint is exposed for retrieving these emails, this includes all data you would expect: subject, content, sender, and most importantly: attachments. You can also get notified of newly received emails using webhooks. The main use-cases I'm thinking of right now is triggering AI agents using email or a very simple document upload flow to any SaaS (just forward an email to the SaaS). This is actually where the inspiration for Recivo came from, I really enjoy the flow of getting an invoice in my mailbox and forwarding it to my accounting software and then seeing it appear in the app. The agentic use-case seems promising, especially for workflows that still require a human in the loop. Asynchronous communication with an AI agent feels natural to me. When you visit the landing page you're immediately given a randomly generated email address and a cURL command to try the API. Of course these demo addresses will expire, so you'll have to log in to create a non-randomized and permanent address. I'm wondering if you see any other use cases for a "programmatic" mailbox. Please let me know what you think!

Today marks ten years, 3653 consecutive days, of running at least one mile every day under the USRSA rules [1]. To celebrate, I built an interactive dashboard that turns a decade of GPX files into charts you can explore. Running has truly changed my life: I've made lifelong friends, explored beautiful places, and more importantly invested into my own health and fitness, which I'm starting to see the positive benefits as I get older. The stack is pretty simple: a NextJS app, with a Postgres database to keep all my running data, and all the stats are pre-computed and cached in Redis, so I…

Made this website as an exercise in vibe-coding and GCP. It was posted about a few times around the internet, on sites like Morning Brew (https://www.morningbrew.com/issues/business-buzzkill), MetaFilter (https://www.metafilter.com/209703/Draw-A-Fish), boingboing.net, etc. I think it's cute! I built a basic CNN trained against penises and swastikas, and then anything that doesn't hit the 63% confidence score gets sent to a mod queue, a vibe-coded fish-tinder…
