What Is a Shared Inbox and How Does It Work?
A plain-English guide to what a shared inbox is, how it works, how it differs from a shared mailbox, and how to choose one.
To add live chat to your website, choose a chat tool, copy its JavaScript snippet into your site's HTML (or paste it into your website builder), then configure who receives the chats and how they get notified. The whole process takes about 15 minutes, and on a managed platform like Messello you never touch a server — you paste one line of code and conversations start landing in your shared inbox.
This guide walks through why live chat is worth adding, how to pick a tool, the exact install steps, best practices that actually move the needle, and the mistakes that quietly cost you customers.
Live chat is one of the highest-leverage things you can put on a website. Visitors who engage in chat are 2.8 times more likely to convert than those who don't, and chat-to-conversion rates average 10–20% versus 2–3% for traditional contact forms. People who chat before buying also tend to spend more per order, because you're answering the exact objection standing between them and checkout — in real time.
The reason is simple: a form is a black box. Someone fills it in, hits send, and waits a day for an email. Chat collapses that gap to seconds. The visitor who would have bounced instead asks "do you ship to Canada?" and buys ninety seconds later. If you're weighing chat against other channels, our guide to what a shared inbox is explains how chat fits alongside email, WhatsApp, and the rest.
Before you paste any code, pick the tool that will live behind the widget. A few things to weigh:

Adding the widget is step one. These practices are what separate a chat box that converts from one that just sits there.
Live chat works best when it's not a standalone box but one channel in a unified inbox — alongside WhatsApp, Telegram, Instagram, Messenger, email, and SMS — with AI handling the repetitive questions and flat pricing that doesn't punish you for growing. That's exactly what Messello is built for.

You don't edit files. Copy the chat snippet from your dashboard and paste it into your platform's custom-code or footer-scripts field (Appearance/Theme settings on WordPress, theme code on Shopify, or the Custom Code embed on Wix/Squarespace), then save and publish. The bubble appears site-wide.
The data says yes. Visitors who chat are about 2.8x more likely to convert, and chat-to-conversion rates of 10–20% far outpace the 2–3% typical of contact forms — because you answer the buyer's exact objection in real time instead of a day later by email.
Set business hours with an away message that collects the visitor's email so they become a lead, and turn on AI auto-answer so common questions (hours, shipping, refunds) get instant replies around the clock. When you're back, the full conversation is waiting in your shared inbox.
