LetterStack
Templates, sending, and logs - without the $20/month markup
What it does
Transactional email APIs are convenient until free tiers cap daily volume - or you pay for SMTP you already have. LetterStack is the developer layer on your own SMTP: Handlebars templates, one REST send endpoint, send logs. Connect Gmail, Amazon SES, Zoho, or self-hosted. Your SMTP, your reputation. No volume caps from us. From $1/mo. First month free through June 30, 2026.

- OSOpen sourcing my email sending startup2019 · ▲38
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
- BABuilt an email marketing platform after paying $230/month2025 · fertit.com · ▲44
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:…
- HWhttps://www.markdownmail.io – Bulk newsletter sender using Amazon SES2014 · ▲18
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…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
