Hey [First Name],
I've been writing on Substack for 4 years (600+ posts at Infinite Zest), and I always hated how my best work just... disappeared into the archive.
So I built something: a way for readers to actually explore your entire body of work through conversation. Think of it like giving your archive a voice.
I noticed you've been writing about [specific topic from their recent post] — exactly the kind of rich archive that readers would love to dig into.
Would you be open to trying it? It takes about 5 minutes to set up, and I'd love your feedback as a fellow writer.
Here's what it looks like: [link to demo]

Recommendation: Create walter@askmystack.com for outreach automation. Luke reviews templates, Walter sends at scale. This keeps luke@askmystack.com pristine for warm leads.
Do you want Walter to have direct send access via walter@askmystack.com, or should he draft emails for your approval first?
Recommendation: Start with drafts for approval, then move to autonomous sending once messaging is dialed in.

We have the product. We have the credibility. We have the playbook.
Now we execute.
