# A customer who isn't home costs you a morning.  
_A text the day before fixes it._

Quotes by email, a reminder text the day before, a quick message when you leave the previous job. Unlimited Messaging sends all of it from your own phone and your own mailbox, for free.

A day on the tools

## Jobs during the day, quotes and texts at night

Unlimited Messaging is an inbox that brings SMS, email and WhatsApp together, sent from your own accounts: the SIM in your work phone, your mailbox and your WhatsApp number.

You start at 7:30, do three jobs back to back, and in the evening, in the van, there are still quotes to send, customers to call back and one who has gone quiet since the invoice. The next day a customer forgot the appointment: an hour on the road for nothing.

With Unlimited Messaging, quotes leave from your usual mailbox, and a reminder text goes out on its own the day before each appointment, from your phone's SIM through the free Android app. Replies all land in one place, and you can ask Claude or ChatGPT to write the follow-up on a quote for you.

What changes

## What Unlimited Messaging changes for a tradesperson

No complicated software: your phone, your mailbox and a few messages that send themselves.

1. 01  
### Reminder texts from your own phone  
The free Android app sends texts with the SIM in your work phone. Customers get a text from your usual number, and you pay nothing extra per message.
2. 02  
### Quotes from your own mailbox  
Connect your mailbox (Gmail, Outlook or any other) and quotes leave from your usual address, not from an address customers don't know.
3. 03  
### Every reply in one place  
Texts, emails and WhatsApp land in a single list. In the evening you answer everything from your phone or computer, without hunting.
4. 04  
### Claude or ChatGPT for follow-ups  
Ask Claude or ChatGPT to write a follow-up on a quote or an invoice. You read it, approve it, it goes out. Free plan, no per-message fee.

Good to know

## Good habits to keep in mind

1. 01  
### Texts to your customers  
Texts leave from your phone and count against your plan. Write to your customers at a normal pace, as if you were sending them yourself.
2. 02  
### An Android phone switched on  
For SMS, the app runs on an Android phone. Keep it charged and connected, like your everyday work phone.

Key takeaway

### Fewer no-shows, fewer evenings on the phone

Quotes leave from your mailbox, reminder texts from your phone, and every reply lands in one place.

FAQ

## Questions tradespeople ask
