24 alternatives to Inbound Email (SMTP) to Webhook
Here's my first (hopefully of many) open source release. A minimal script to receive emails via SMTP, parse content (including headers), store attachments in Amazon S3, and forward email content to a webhook. I use it to power DMARC report storage and email content testing. Some of the big email API providers have inbound APIs but costs can rack up fast if you're using them at scale. Hence why I built this. https://github.com/sendbetter/inbound-email Features - SMTP server to receive emails concurrently - Parses incoming emails using mailparser - Uploads attachments to…

inbound ▲227Hey HN! I've been working on Inbound (inbound.new) - an email system that lets you programmatically manage email addresses and route them to AI agents, webhooks, or forward them anywhere. The core idea: instead of manually managing email addresses, you create them on-demand via API and route incoming emails to your AI agents or other automated systems. For AI Agents: Create [email protected] and emails get sent to your AI agent as webhooks. Your agent can reply using our SDK. Perfect for AI customer support or automated responses. For Email Forwarding: Set up [email protected] to…

Hi HN! We're a 5 person team working on simplifying the creation of email apps. Right now, most email services focus on outbound emails (newsletters, transactional, delivery), but that doesn't solve the fact that we all hate receiving them. You can try it at https://mailscript.com Mailscript lets you create programmable email addresses. It works headless, via the CLI, API (we use Swagger to support most languages). You can even run it as a daemon on a server (to run functions when emails arrive). Once you get [email protected], you can create as many aliases as you'd like…

HookBox▲120Debugging webhooks and transactional emails can be slow and usually requires multiple tools. I built HookBox to solve this problem, providing instant endpoints, temporary inboxes, real-time capture, and request replay so both can be tested in one place. Would love to hear your feedback! — Egret

Hey HN, I built this tool a while ago, and it looks like it's finally getting some traction lately -- wanted to post it up again here for anyone who's looking for a dead simple solution for webhooks that email you. For those who say new products are hard to trust ("you never know how long they'll be around!") -- this one has been casually running for just over 13 months now! https://webhooked.email

Hi everyone, My motivation for building this was to address the trouble of mass unsubscribing from unwanted emails and deleting bulk emails while ensuring privacy and control over the process. With this Chrome extension, emails are not sent to any external servers. All calls to the Gmail API happen locally on your device. Feedback and suggestions are welcome!

Hi all, I've posted a few times here about Maildown, a startup that I've been trying to validate lately. Due to lack of time to focus on this, I've taken the decision to abandon the project as a startup, but to make it available as an open source solution instead. The (still very basic) github repository is here: https://github.com/chris104957/maildown Maildown now exists as a simple CLI wrapper for Amazon SES which bakes in Markdown and styling support, making it much easier to get transactional mails up and running in any project Thanks for looking, Chris

Hi HN, I host my own mail infrastructure and don't rely on third-party tools to send my mails. But in a microservice architecture, managing all the SMTP configs quickly becomes tiresome. After a while I'd always have my credentials and settings scattered in application-properties, bash scripts and environment files. So I've build Brieferl, an app where you can add your SMTP servers and send emails through a single API with a simple JSON payload. You also get logs of when/where emails were sent and HTML previews of messages. I am interested in what you guys think about this. You can…

KaiMail▲6I've always had the need to quickly just setup an email service for all the different projects and communities that I run, so I built KaiMail to do that. I can't stand the fact that getting emails for your domains can be so difficult compared to setting up a static website. If you're running an open-source project or an open-source community, I'm happy to get you an upgrade at no cost.
