# Prospects reply everywhere.  
_Read them in one place._

One prospect answers on WhatsApp, another by email, a third by text. Unlimited Messaging puts them in one inbox, from your own number and your own address, and follows up for you.

A day in sales

## Three apps open, and one follow-up forgotten

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

In the morning you email three quotes. At noon a prospect replies on WhatsApp while you are in a meeting. In the evening someone else texts you. Each conversation lives in a different app, and the follow-up planned for "in three days" slips through the cracks.

With Unlimited Messaging, everything lands in one place. You reply from the web app on the channel the prospect used, with your usual number and address, so nothing looks different to them. Follow-ups can go out on their own through n8n, and Claude or ChatGPT can draft or send a reply when you ask.

Same idea for [real estate agents](https://unlimitedmessaging.app/articles/real-estate-agent-whatsapp-follow-up-ai) and [freelancers](https://unlimitedmessaging.app/articles/freelance-claude-answers-whatsapp). The email channel is explained on [the Email page](https://unlimitedmessaging.app/channels/email).

What changes

## What Unlimited Messaging changes for a salesperson

You keep your accounts and your habits. You gain one overview and follow-ups that no longer depend on your memory.

1. 01  
### One inbox for every channel  
WhatsApp, email and SMS in the same list. You see at a glance who replied and where, without jumping between apps.
2. 02  
### Your accounts, not a borrowed number  
Link your WhatsApp number by scanning a QR code, your mailbox over IMAP/SMTP and your SIM through the Android app. Prospects get your messages as usual.
3. 03  
### Follow-ups that send themselves  
With n8n, a quote sent three days ago with no answer triggers a WhatsApp or email follow-up, from your own number or address.
4. 04  
### Claude or ChatGPT as an assistant  
Ask Claude or ChatGPT to sum up your latest conversations, draft a follow-up or send it. Nothing goes out without your approval. No per-message fee on the free plan.

Setup

## Ready in 3 steps, in under 10 minutes

1. 01  
### Create your account  
Free sign-up, no credit card. The free plan sends unlimited messages.
2. 02

3. 03  
### Reply and automate  
Reply from the unified inbox, then plug in n8n for follow-ups or Claude and ChatGPT to draft for you.

1. 01 · WhatsApp  
### After a first call  
Hi \[First name\], thanks for the call this morning. As agreed, I'll email you the proposal within the hour. Feel free to reply here if that's easier for you.
2. 02 · Email  
### Quote follow-up, day 3  
Hi \[First name\], Just checking in on quote \[reference\] I sent on Monday. Have you had a chance to look at it? Happy to adjust a line or talk for 10 minutes this week. Best, \[Your name\]
3. 03 · SMS  
### Meeting confirmation  
Hi \[First name\], confirming our meeting on \[day\] at \[time\] at \[place\]. Something came up? Just reply to this text. \[Your name\]
4. 04 · WhatsApp  
### Last follow-up, no pressure  
Hi \[First name\], I don't want to crowd your inbox: if the project is on hold, a quick "not now" is all I need and I won't follow up again. Thanks!

Good to know

## Good habits to keep in mind

1. 01  
### WhatsApp, for your real contacts  
Write to prospects who know you or gave you their number. Bulk messages to strangers get a number blocked, whatever the tool.
2. 02  
### SMS at your own pace  
Texts leave from your phone and count against your plan. Keep a human pace, as if you were sending them by hand.

Key takeaway

### One inbox, your accounts, no forgotten follow-up

Prospects write wherever they like, you answer from one place with your usual number and address, and follow-ups go out on their own.
