Products that do what Inbound Email (SMTP) to Webhook does

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…

    Hi HN! We’re Aleem, Chris, Borys, Meichen and Zach from Streak (YC S11) and today we’re open sourcing our InboxSDK https://www.inboxsdk.com, which makes it easy to build apps for Gmail. Over 1.8B users spend their days in Gmail! Having your app built into the Gmail workflow is a better user experience and gives you great user retention. InboxSDK gives you a high-level, declarative API to insert your UI into Gmail without having to directly manipulate the DOM yourself. End users install a browser extension to use your app. The SDK can add UI to multiple areas of Gmail. For example,…

    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…

    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…

    Hey HN, I spent the long weekend on a small tool for sending myself emails via webhook. Yes, webhook-to-email in 2023 (somehow most things I could find are email-to-webhook or not quite easy to set up). Yep, I'm aware this problem is very much already solved(tm) in a bunch of ways: - Zapier exists - IFTTT exists - Slack webhooks exist (this one is probably what normal people would pick) - Native email integrations usually exist in whatever tool in the first place Somehow, I still find myself wanting a super easy way to get an email delivered to me when a webhook endpoint is hit (via POST or…
