Hey HN, I'm Chris, CTO of Knock (https://knock.app). We built email.info because every developer we talk to asks the same question: which email provider should I use? The existing resources are mostly vibes — "Best of" listicles, anonymous Reddit threads, or LLM answers trained on that same content. Objective performance data is always missing. Knock is a notification infrastructure platform, so we send billions of API requests to downstream email providers every year. We aggregated that data into a public dashboard covering 10 providers (SendGrid, Postmark, Resend, Mailgun, Amazon…

Spent the last month building Fertit - basically a newsletter manager but you bring your own SMTP and skip the DevOps nightmare. All the features (subscriber management, admin dashboard, custom preferences) without the infrastructure markup. The math that broke me: Mailchimp: $230/month for 15k contacts My solution: $10/month infrastructure + $10 SendGrid = unlimited What I learned: The "enterprise" features are mostly database operations with SMTP APIs. But the 3 weeks of Go/PostgreSQL/Redis setup explains why people just pay ConvertKit $300/month. Here's the thing:…

We recently launched a new project called https://www.markdownmail.io The motivations behind https://www.markdownmail.io was that we wanted to be able to occasionally send out an email to our user base. Currently we have over 100k subscribers and on average send an email once every other month. With the mailchimp it was costing us $475 per month. That's a lot of money to send an occasional newsletter. So we started to look for alternatives. We decided to move to sendy.co which is self hosted and uses SES. Whilst the costs where lower we found the product unstable and…

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 :) 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…

Hey folks at HN, I didn’t want to pay $10–$30/month for AI email tools, so my friend and I built a free Chrome extension that works directly inside Gmail. It has the core features you'd expect: - When you open a reply, it drafts a response based on the thread — just hit Tab and send. - As you type, it suggests completions based on context (like autocomplete, but smarter). - Press Shift+Tab to force a suggestion anytime. - You can also give it context with // comments — e.g. // suggest a time on Thursday afternoon — and press Tab to drop in the response. Then hit…

Alot of companies (Including the one i work at fulltime) use third party email builders to provide custom email functionality to users. However this is a niche sector and the prices are... insane? So to try and fix this i built Maillune, a embeddable emailbuilder sdk that is alot cheaper with a usable free tier for hobby projects. The entire goal was to make the features transparent and logical. With lower focus on feature paywalls and aiming on a more "Out of the box" approach. This is one of my recent projects ive built in parallel with my fulltime job. All feedback is welcome, good or bad!
