Products that do what Mail client optimized for self-hosted email across multiple domains does
As someone with a clean IP range and ADHD, I manage my inbox by splitting across a variety of accounts for a variety of domains. I’ve never really found a client that scratches all my itches, so I spent some time making one and it’s now become my daily driver. It’s optimised to be visually simple and highly configurable for things like colour, folders/subfolders, sorting and tweaking the search query function to better match what you search for often. There’s also some little nice-to-haves like a purpose-built PWA, bulk domain onboarding, MCP and dark mode. It’s fully self-hostable,…

Hi HN :) really excited to share this with you. The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels…

Dan Ariely and I are looking for ways to help people with high email load. One idea was Shortwhale, which we've tested for a few months now. The idea is super simple: It's a place to tell people how you prefer email and it offers a simple contact form that adds the necessary structure to email. Although technically trivial, it works extremely well for Dan. We have ideas on how to expand this but first we'd like to know if someone else might find this useful too (we know that this is only a solution for people who get tons of (unsolicited) email). Underlying to all of this is the idea to put…

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…

Built this after getting frustrated with the paying to a google for email. Now running it for 1 months in production. What it does: - Full SMTP server (inbound/outbound, DKIM signing, SPF/DMARC checking) - IMAP with IDLE support - CalDAV/CardDAV (replace Google Calendar/Contacts) - Web admin panel with Prometheus metrics - Greylisting for spam prevention - Auto-discovery (mail clients configure themselves) - Audit logging for compliance What it doesn't do: - Webmail (use Roundcube, etc.) - ML-based spam filtering (greylisting + basic heuristics only) - Clustering/HA

TemporaryMail.com was created after struggling to find a working, secure and reliable service which provides temporary email addresses. The goal is to keep this service as simple to use as possible - while also always providing a free option which does not require registration. Some of the features: - Multiple domains to choose from, each with unique hostnames and IPs. - Support for inline images in emails. - Attachments are supported and can be downloaded. - Read your emails safely inside a sandbox (all external scripts disabled). - Read emails without automatically loading any external…

Hi HN! I'm Louw, founder of the enterprise insurtech scale-up Root[0]. Over the last 8 years, my inbox has been flooded with unsolicited emails, especially since early 2023. Recruitment services, outsourced software development agencies, and a crazy amount of lead generation services (thanks, Apollo!) drowned my inbox. To solve this, I created Unspam. Initially, it was a simple tool for myself and fellow founders to reduce noise. And it worked — about 10% of my emails were swiftly and accurately categorized as unsolicited messages. Given its success, I've decided to package and share Unspam…

I recently discovered Cloudflare Email Routing. It's a super sweet feature within Cloudflare for creating disposable emails. Basically, if you have a domain connected to Cloudflare - you can create email addresses like "[email protected]" that can forward emails to your primary inbox (Gmail, Outlook, Apple Mail, etc.). This is great since you'll never need to share your real email address when signing up for new online services again. It will help you keep your primary inbox free from spam and promotional junk! However, managing my disposable emails using Cloudflare's UI is not…

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…

Hey, Recently, I was blindsided by my web hosting plan renewing at almost double its initial cost. This unpleasant surprise prompted me to create Match My Hosting. As a hobby coder, I built this straightforward tool in my spare time using dead simple PHP, HTML, and JS with the massive help of ChatGPT-4. The tool currently includes around 30 providers with 120 different packages. It uses Trustpilot reviews to guide the recommendations, ensuring you choose a host that's not only technically suitable but also well-regarded by users. And to avoid any surprises, it also clearly displays both the…
