How to write proactive messages that sell

You've just switched on live chat on your e-commerce store. Now you're facing the question that matters: what do I write, and when? A proactive message is a message that goes out first — you don't wait for the shopper to reach out, you open the conversation. But it goes out based on context: the page the person is looking at, how long they've been sitting still, whether their cart is full and they haven't moved on. And it's the timing, far more than the words, that decides whether that message sells or annoys.

The same line — "Need a hand with sizing?" — works beautifully on a product page and turns irritating if it pops up three seconds after landing on the homepage. The text isn't wrong: the timing is. In this article you'll find how to pick the right moment and what to write in the situations that matter most, with ready examples to adapt.

When should a proactive message go out?

A proactive message goes out once the person has already shown a signal of intent, not the moment they set foot on the site. Opening a conversation in the first few seconds, while the visitor is still getting their bearings, is the fastest way to get ignored or have the chat closed. Better to wait for the context to tell you something.

The moments that almost always work:

• On the product page, after the person has spent a few dozen seconds there: they're weighing it up, help is welcome.
• On a stalled cart, when the shopper has added items but hasn't moved to checkout for a while.
• On the shipping or returns page, where readers often have one specific doubt holding them back.
• On a return visit, when someone reopens a page they've already seen: purchase intent is warm.

Visitors who engage with a live chat convert at a noticeably higher rate than those browsing on their own (industry benchmark — source: iAdvize). But that figure only materialises when the message arrives while the person is receptive. Any earlier, it's noise.

What do you write to someone with a stalled cart?

To someone with a stalled cart, you write by clearing the specific doubt that's blocking them, not a generic "can I help?". Cart abandonment industry-wide sits around 70% (source: Baymard), and the most frequent causes are few and well known: unexpected shipping costs, uncertainty about sizing, doubts over returns, last-step hesitation. The best message heads off one of these.

A few concrete examples:

• "I see you've got a couple of items in your cart. If shipping is what's holding you back: it's free over €49, and you're almost there."
• "Not sure about the size? Tell me your height and weight and I'll tell you which one to get."
• "Returns are free within 30 days, if that's what's giving you pause. Anything else before you decide?"

Notice the difference: you don't ask "can I help", you offer the answer up front. Someone who knows the catalogue can recommend the right size, offer an alternative when an item is sold out, flag the free-shipping threshold — and in doing so move the average order value too. The ROI calculator shows you what it's worth to recover even a fraction of those carts.

How do you avoid being intrusive?

You're not intrusive if the message lands at the right moment, in a human tone, without chasing someone who's already said no. Intrusiveness doesn't come from writing first: it comes from the wrong message at the wrong time. A pop-up that jumps at you the second you land, repeated on every page, is intrusive. A relevant line in front of a real doubt almost never is.

A few rules that keep the conversation on the right side:

• One message per visit, unless the person replies. If they don't answer, don't push it by changing pages.
• Context, not a script: the message should refer to what they're looking at, not a line that's identical across the whole site.
• Human tone: "Need a hand with sizing?" reads like a person; "Would you like product assistance?" reads like a form.
• Easy to dismiss: anyone who doesn't want to talk should be able to ignore the message without feeling cornered.

The chat that sells is the one with real people behind it — who read the context and know when to stay quiet. It's the opposite of a chatbot that fires the same opener at everyone: blind automation is what makes most chats intrusive.

Which messages work during sales?

During sales, the messages that work are the ones that create genuine urgency and clear the last doubt, because the traffic already carries high purchase intent. On those days the person came to buy: you don't need to convince them, you need to remove the friction stalling them on the final step. The proactive message is worth double here.

Examples that suit the sales period well:

• "This item is one of today's bestsellers and size M is running low. Want me to hold it while you decide?"
• "The sale discount on this product ends tonight. Any doubts before you complete the order?"
• "One more item and you clear €49, so shipping becomes free. Want me to show you what pairs well?"

The urgency lever only works if it's real: if the size really is running out, if the discount really does expire. Inflated promises backfire.

How do you tell which messages are selling?

You tell which messages sell by looking at how many proactively opened conversations end in an order, not how many times the message went out. It's easy to fall for the number of chats opened, but the metric that counts is another: the conversion rate of proactive conversations.

What to keep an eye on in the first few weeks:

• Conversion rate by message type: does the stalled-cart message convert better than the product-page one? Shift your energy to where it pays.
• Reply rate: if a message fires often but almost nobody answers, the timing or the text needs a rethink.
• Average order value of assisted conversations: are the chat suggestions nudging orders higher?

Two or three well-tuned messages are enough to start seeing results; then you refine by reading the numbers. The features section shows which of these metrics you can follow in real time, and the conversions guide frames how the chat fits into the rest of the funnel.

Where do you start with your first messages?

You start with a few messages, on a few clear moments, and improve them as you go. The most common mistake right after switching on the chat is wanting to cover every page with a different message from day one: the result is a site that talks over its visitors without selling more. Better to start with two or three solid triggers — stalled cart, product page, shipping page — and watch what happens.

So you're not starting from a blank page, we've gathered the openers that convert best into a ready-to-use lead magnet: 12 proactive messages to copy and adapt to your catalogue, sorted by moment in the funnel.

The right first messages are the ones a person would actually say, to the right shopper, at the moment they're deciding whether to buy — and from there, every conversation that ends in an order tells you which path to keep taking.
