24 alternatives to Email API benchmarks
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…

Hi all! Excited to share cc.dev after months of work and refinement. The idea for this product came from trying to do email marketing for my side project, CubeDesk, a site where Rubik's Cube enthusiasts can time themselves, race with one another, train algorithms — it's a fun niche! With over 40k users, sending even a single campaign was becoming expensive with MailChimp. I knew AWS SES would be much cheaper, but it’s just an API with none of the other necessities you need for a robust email marketing platform. Beyond cost, I was also frustrated with having to make sure my database was…

I recently built a small open-source tool to benchmark different LLM API endpoints — including OpenAI, Claude, and self-hosted models (like llama.cpp). It runs a configurable number of test requests and reports two key metrics: • First-token latency (ms): How long it takes for the first token to appear • Output speed (tokens/sec): Overall output fluency Demo: https://llmapitest.com/ Code: https://github.com/qjr87/llm-api-test The goal is to provide a simple, visual, and reproducible way to evaluate performance across different LLM providers, including…

Dirac▲128It all started 4 months ago during my last startup. Even with barely any traction, I was getting about 20 emails a day. Some from cold randoms, some internal, some from prospects. And I just wasted so much time in my inbox. The current solutions? Superhuman and HEY. Sure they're pretty but the ai is just an after thought. And the tool that was supposed to help me just makes me, my own assistant. So I went and built Dirac. We're launching in 8 hours, https://www.producthunt.com/products/dirac-3?launch=dirac-4

Hey HN! I’m Chris – one of the co-founders at Knock (https://knock.app). Knock is notifications infrastructure for developers. We provide a set of flexible API primitives you can use to power complex notification systems, without having to roll your own notifications infrastructure in-house. In short: we built notifications so you don’t have to. We learned about scaling notifications systems the hard way. Previously, my co-founder and I worked together at Frame.io, where we saw the upside of product notifications as well as the pain involved in building and maintaining them. With…
