24 alternatives to HappyMail
Eight years ago, I was job hunting and felt embarrassed by my Gmail address. I tried registering firstname.lastname — taken everywhere. So I thought: "I'm in IT, I'll set up my own domain with my own IMAP/SMTP. How hard could it be?" A lot went wrong. Forgotten renewals. rocky DNS mistakes. I ended migrating toward Google Workspace, but in the end it felt overkill, having a subscription there plus the whole registrar subscription, and the whole GAFAM sticker on it. Moreover, the final price was way too high for me at the time. Six months ago, someone approached me and related to that…

Back in 2010 I had an idea for a service that would allow people to easily create semi-permanent email aliases so that they could give an email address to people and websites without revealing their real email address. These aliases will continue to work indefinitely unless you choose to block them. My brother and I spent a few months building the initial version and launched the website in July 2010. For the first year we had about 50 signups per month, by 2013 this had increased to 1500 and it's currently around 3500 per month. Similarly, our revenue grew consistently but slowly - doubling…

Hello Inbox▲283Hey HN, I built an email deliverability SaaS with a RAG system. It's trained on all my knowledge and hundreds of real deliverability use cases from 4+ years experience as an Email Deliverability Specialist on Upwork. It solves a frustration problem a lot of businesses are experiencing. I'm looking for feedback so let me know in the comments.

Made this privacy conscious temporary mail extension as a hobby a few years ago as I found a cool domain. I've now revamped the UI, added more domains and created an extension that shows your inbox in your browser (it only asks for permission to read from TemporaryMail.com and not all sites like the other extensions), it's also free from ads (paying the service out of pocket and perhaps adding an upgrade feature later on). What makes this site a bit more unique is that I wrote the email parser from scratch following the RFC (took me 2 months and tons of testing) so it should display all…

Emalias.app▲12This project started basically because I got loads of spam from random Gmail addresses, and I wanted to answer the question: 'how are they getting a hold of my e-mail'. My e-mail address is pretty unique and not very easy to guess. That's what led me to build emalias.app - a service which allows you to create individual e-mail addresses (such as [email protected]), which forward to your real inbox. This concept completely hides your primary e-mail address, and gives you great oversight over which services are selling your data to third-party advertisers. If a certain alias starts receiving…

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.

Hey HN, I’m a solopreneur and have been in the SaaS space for the past 3 years. My last 3 startups failed, and a common challenge in all of them was figuring out how to reach my audience. Recently I started with cold outreach (its a struggle, since I dont have much experience with marketing). I am finding leads mainly using exa.ai websets (web vector search, extremelly good for multiple use cases, recommend checking them out) and then sending them through smartlead. I ran the campaign for the past 30 days and 12-15% emails always bounced. This wasted my email credits & chances of reaching…

I built *Tempmail3*—a lightweight, disposable email service that works instantly and requires *no signup or verification*. *Why I built this* I often needed quick email addresses for testing or sign-ups—but existing services were slow, cluttered, or required entering my real email. So I built Tempmail3 to be as fast and frictionless as possible. *What it does* - Generate a temporary email with one click. - View incoming emails in real time via the browser. - Discard or regenerate the address anytime. - (Optional) This is an open-source project: [GitHub link]. *Technical details & challenges*…

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…

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…

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,…
