How to Use a Call Whisper to Grow Your Marketplace

Do you have trouble attracting and retaining sellers in your marketplace because they don’t know how many clients you send their way? Your marketplace could be sending your sellers 90% of their leads, but if your sellers aren’t aware of that, they might lose their trust in your website.

How can you make sure your sellers know about the valuable leads they are receiving in return for their investment in your marketplace – without them having to ask incoming callers directly?

Call Whispers

That’s where Call Whispers come in. Call Whispers are a tool that helps your sellers know how many customers your marketplace sends their way.

What is a Call Whisper?

A call whisper is a pre-recorded message that helps sellers on your website attribute the source of incoming calls to your marketplace.


Most sellers have a multi-channel marketing campaign with listings on competitor sites as well as on other platforms like Facebook, local newspapers, or yellow pages. Call whispers let sellers know which calls are originating from your marketplace to justify their investment.

Marketplace sellers don’t like to ask customers the source of their calls because it interrupts the flow of the conversation, which might affect conversions. Call whispers eliminates the hassle of having to ask callers this question.

Companies like Zoopla, AutoTrader, and OnTheMarket (major European marketplace portals) use call whispers & alerts to attribute the source of leads.

How do call whispers work?

When a seller posts products for sale on your platform, unique, virtual, toll-free numbers or local numbers are assigned to those ads.

When a prospect is interested in your marketplace listing, they call one of the seller’s toll-free numbers or local numbers mentioned in the listing.

When the seller picks up the phone, he or she will hear a short, pre-recorded message saying, “This call is from X Marketplace” before hearing the caller’s voice.

This recorded message takes three to five seconds and immediately lets your seller know that the call originated from your website. The person who dialed will continue to hear ringing on their line while the short message plays.

When does the call whisper play?

Worried that whisper messaging will interrupt your conversation?

Don’t be!

The whisper message doesn’t play when you or the caller are speaking. It plays when you pick up the call while the caller continues to hear ringing. Somewhat like a queue in an IVR (except that it’s just for 3-5 seconds.) The call only begins after the brief recording has ended.

How do Call Whispers Help?In addition to lead source attribution, call whispers help you and your marketplace sellers in several ways:

Optimize ad performance

When you know how many prospects are calling for your products, you can easily track the performance of your ad sources.

Think about it.

When sellers and their sales teams know that the calls from the toll-free numbers or local numbers of your online marketplace outweigh the calls from social media campaigns and newspapers, deciding which ad campaign to invest in becomes an easy decision to make.

When sellers know the ROI from your marketplace, they usually decide to add more listings to your website.

Close More Deals

Don’t you find it a waste of time when contact center agents start talking about a service you’re not interested in?

Your buyers don’t like it either.

With the whisper message feature, sellers know exactly what the prospect is inquiring about before they even answer the call. For example, in the auto industry, if the caller wants to know about the deal offered on used Toyotas online, the seller will begin to talk to them about the Toyotas and not about the new stock of Teslas also being advertised in the paper.

Engagement that is direct and concise makes a caller happy, and happy callers mean increased sales.

Shortens call duration

As a result of the above, a call whisper saves you tons of time. Eliminating unnecessary dialogue and directly addressing a customer inquiry saves both the seller and the buyer tons of valuable time.

Keep a Permanent Record

In addition to the call whisper feature, missed call alerts can be integrated with an email or text message. When sellers miss an incoming call from a buyer on your marketplace, they can choose to receive an email and/or SMS alert to keep track of how many leads their business has received through your platform.

Managers can also use this data to analyze incoming lead patterns – separately, or in conjunction with their IVR data.

Improve Customer Service

Similarly to how Call Whispers work for new prospects, they can also be used for existing customers to increase customer satisfaction.


Unique virtual numbers can be assigned for each product. So when a customer calls, there is no need to take them through an automatic call distribution system like an IVR.

Support team members will know that incoming calls are about a specific product before they answer a call and can provide a better customer experience. This works well for companies of all sizes.
