Inbox Echo started as a throwaway idea.
I was working on a YouTube tutorial and someone joked about building a tool to "reply" to cold outreach messages—the kind that start with "I noticed your profile…" and end with a calendar link.
It was funny because it was familiar.
Everyone with a public inbox has seen the same message, just with different names swapped in.
The first ideas were… not exactly shippable. They were funny, but they crossed legal and ethical lines pretty quickly.
So instead of building something retaliatory, I asked a simpler question:
"What's the cleanest, most honest way to show how these messages actually land?"
Keeping It Simple (and Legal)
Inbox Echo doesn't spam anyone.
It doesn't trick people into subscribing.
It doesn't pretend to be a scheduling link.
That stuff might be entertaining, but it's not responsible—and it's not something I wanted to teach or ship.
Instead, Inbox Echo does one thing:
It shows how a message blends into the noise.
That's it.
What Inbox Echo Is
You paste in an outreach message. Inbox Echo reflects it back with a bit of context, a bit of data, and a bit of personality.
Sometimes that personality is professional.
Sometimes it's dry.
Sometimes it's clearly "please don't follow up."
It's meant to be light, a little sassy, and very final.
No advice.
No rewrite.
No ongoing conversation.
Just a clear signal.
Why It Exists
Inbox Echo wasn't built to fix outreach or coach sales copy.
It was built as a small, contained idea for a tutorial that turned out to be genuinely useful.
It gives people a way to respond once—without escalating, without ghosting, and without turning into the thing they're frustrated by.
And yes, it's a little funny.
Because sometimes the best way to make a point is to hold up a mirror and let it speak for itself.
