we've been updating our system prompts at @brewdotnew after @AnthropicAI showed which old habits slow down Claude Opus 5.5

@andruyeung Building @brewdotnew to help small and big teams do beautiful, on-brand lifecycle marketing with ease
Based on my experience (and frustration) launching @Revolut in the US
When I was thinking about starting @brewdotnew, I came across some industry research saying it takes an average of 8.21 business days to launch a single email campaign
It matched my experience from @Revolut exactly
It was immediately clear to me that design and iteration speed was the biggest bottleneck, and that Brew at its core would have to make that 100x faster. Going from idea to a finished, on-brand email shouldn't take days of back and forth
But there was a second reason it took sooo long, and it's related: how fragmented the tools were. The brief in one doc, the copy in another, the design in @figma, feedback in @SlackHQ, a rebuild in the ESP and then test sends to @Outlook to see what broke. At every step the email just sat there waiting for someone
So we built Brew to solve both. AI gets you from prompt to a finished, on-brand email in minutes, and everything after that happens on one canvas where your stakeholders comment right on the email
And because it's all visual, you can see exactly what the AI did before anything goes out
wdyt? how long does it take your team to get a campaign out the door?
