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.

GeminiA 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 and freelancers. The email channel is explained on the Email page.
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.
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.
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.
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.
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.

Good to know
Good habits to keep in mind
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.
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.
