Lead follow-up for a plumber

Northfield Plumbing Co. is made up for this example. The code is real and open: read it or run it.

The week below, in under a minute: every line and every email is the code’s real output. No sound needed.

The problem

A plumber on a job can’t answer email or the website form. Inquiries sit for hours, and the customer books the next plumber on Google.

What it does

An instant reply to every inquiry: when you’ll call back, and what to do in an emergency
An alert to the owner with the name, phone number and message, ready to call back
A friendly follow-up after 1 day and after 3 days, stopping the moment the customer replies or books
The same person sending the form twice is one conversation, not two replies

The messy parts it handles

MARIA GONZALEZ typed in capitals becomes Maria Gonzalez
A typo like @gmial.com is fixed; phones in any format become +1 507 numbers
No usable email or phone: straight to the owner, never into a void
A follow-up that falls due at night waits for 9 a.m.
