Re: your inbox
A particular “Newsletter Guide” launched on Product Hunt recently and caught our eye. Yes, this newsletter is about to get very meta.
The Newsletter Guide is a collaboration between email gurus Yellow Brim, The Shorenstein Center and Lenfest Institute. It's not an intro-level newsletter course, but more of a “201”-level toolkit of resources, strategies and open-source templates for people who run newsletters to collaborate on.
The idea behind the project is to reduce the technical strain behind making a newsletter, and allowing editors to focus more on editorial. Some things the Newsletter Guide covers:
- How to grow your email list
- How to monetize your newsletter
- How to evaluate success metrics
- How to track where subscribers found you
- How to avoid accidentally breaking laws
And soooo much more.
The Newsletter Guide comes alongside an uptick in products that make it superrr easy for people to launch newsletters without much hassle. Here are a few:
💌 Substack gives writers a CMS built for publishing paid newsletters
💌 Revue helps you quickly spin up a personal newsletter
💌 Email Newsletter Checklist helps you send error-free emails
💌 Good Bits lets you create newsletters from the best links on the web
💌 Send Check It helps you write better email subjects
💌 EmailDrips is like Dribbble for email drip campaigns

Your agents stopped answering and started doing
Your agents call tools, write to databases and move money, so a wrong answer is now a wrong action, which is a considerably worse meeting. Arcjet runs policy before every LLM call, tool call, query and API request: prompt injection, sensitive data, bots, rate limits, spend quotas, and your own rules in Rego on top. It reads the OpenTelemetry you already emit, so switching it on is one environment variable, no code changes and nothing to deploy. Each check also reads the earlier steps in the same workflow, so an agent's tenth action gets judged against the first nine and not on its own. JavaScript, Python and Go SDKs all at 1.0, agent framework guards included, free tier to start on.
