Most founders building outbound for the first time don't know what infrastructure they actually need.
They buy five domains, set up one inbox each, fire 100 sends a day, and wonder why deliverability craters in week three.
The Email Send Calculator takes your daily send target and outputs the domain count, inbox count, and warmup timeline required to hit it cleanly.
One input. Four outputs. No manual math, no guessing at setup.
Comment "CALC" and I'll DM it to you. Must follow to receive.
