Products that do what Hello Inbox – Free email deliverability checklist for marketers does

After struggling with low open rates in my small lifestyle software business, I decided to go down the rabbit hole that is email deliverability, learned a bunch of things I didn't know even after being in tech for a decade. A/B tested a bunch of things and finally got good results. I then decided to put together a comprehensive checklist of everything I learned and got me results to share with others. Now I help companies fix poor email deliverability and boost their email ROI. I want this checklist to be a repository of email best practices so I'm always looking to improve and update…

    I’m thrilled to finally be able to show everyone what we’ve been working on for the last 2 years. We’re re-inventing the email experience to help you email smarter and faster, so you can get more done, and maybe even actually enjoy your inbox. When we launched Firebase here 10 years ago, HN was tough but fair, and I expect no less this time around! I hope you’ll check out what we’ve built and share your feedback. I’ll be around here all day and am happy to answer any questions. Let us know what you think!

I wanted to share something we at Good Enough (https://goodenough.us) built over the past year: Jelly! https://letsjelly.com Jelly is a simpler shared inbox for small teams (like us) to answer team email. We had just been sharing a login to Fastmail previously, but as email started getting busier, that really started to stink as a solution — no one knew who was going to answer what, if someone else saw an email or not, etc etc. And a Google Group would prove to be worse, as replies too easily got lost to personal inboxes if someone accidentally didn’t “Reply…

End users install a browser extension to use your app. The SDK can add UI to multiple areas of Gmail. For example,…

    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…
