I used to spend 4+ hours a week running my newsletter

now it's just a few minutes

I've written my newsletter for two years but everything changed six weeks ago with the @beehiiv MCP

here are the 5 workflows that got me there 🧵

1/ newsletter editor

claude analyzed every newsletter I've ever sent and built a style guide based on my voice

now I submit a rough draft → it fact-checks every claim, fixes flow and grammar, and returns a publish-ready version

everyone can have their own dedicated editor

2/ subject line generator

claude discovered clear patterns and correlations between subject lines and open rates

ex: abstract nouns like “trajectory” crush (46.9%)
ex: using “beehiiv” hurts open rates

it built a framework called CREAM. now every subject line is backed by data

3/ ad copywriter

claude found certain framing that increased clicks, and other phrases that caused lower open rates (i.e. too promotional)

now it rewrites ad copy in my voice and runs it through a deliverability filter

result: higher open rates, better ads, happier sponsors

4/ ad performance report

each week I owe sponsors a performance report. it used to take 20 minutes clicking through dashboards

now → every Tuesday claude automatically pulls data from beehiiv and builds a PDF with the advertiser’s logo and BDE aesthetic

zero input from me

5/ advertiser lead gen

cold outreach sucks. I built an AI tool that:

> segments new subscribers
> identifies the companies they work for
> scores them against my ideal advertiser profile
> sends me qualified leads in Slack every morning

warm leads. no effort. every single day
