24 alternatives to inbound
Hey 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…

Hey HN, we're Haakam, Michael, and Adi. We're building AgentMail (https://agentmail.to/), an API to give AI agents their own email inboxes. We’re not talking about AI for your email, this is email for your AI. We started building email agents because they can converse with users in their inboxes, automate email-based workflows, and authenticate with third-party applications. Given these unique capabilities, we think email will be a core interface for agents. But we were building on top of Gmail, which was a struggle: poor API support, expensive subscriptions, rate limits,…

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…

Empower your product manager. Let them decide what the messages to your users say, when those messages are triggered, as well as how they are sent (sms, email, etc.) while you focus on building product features. They'll be able to use trusted providers like sendgrid, twilio and apple so you don't have to worry about message delivery.

Hi HN! My co-founder and I spent the last 4 weeks building something we desperately needed ourselves. The Problem: We spend hours processing emails - scheduling meetings, going through long newsletters, downloading attachments to review, verifying documents like invoices, and of course taking actions on external systems (Salesforce, Asana, Jira etc) based on emails received. A lot of this can be automated with the help of AI agents, saving several hours every week. Our Solution: Forward any email to a specialized AI agent that completes the task and email you back the results. No…

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…

I kept running into the same problem while building AI agents: every agent that needs email ends up sharing my personal inbox or a single company domain. That breaks attribution, creates deliverability risk, and makes it impossible to test sender identities per agent. So I built AgentMailr. You call an API to create an inbox, your agent gets a unique email address, and replies route back to that specific agent. Works for both inbound (OTP parsing, reply routing) and outbound (cold email, notifications). Bring your own domain is supported so emails come from your domain, not ours. REST API…
