Service features

You can contact your customer by phone immediately after he/she reads the e-mail message you have sent. Alternatively, our system can "play" an offer you wrote earlier for such a client.

  • Choose your e-mail provider

    For your convenience, we have developed an integration with the best e-mail newsletter systems: SendPulse, MailChimp, and Mailgun. If there is no integration with the e-mail newsletter service you need, write to our customer support service and we will implement such an integration as soon as possible.

    2-3 minutes – and you can launch your campaign.

After that, our system will do everything else by itself.

Questions and answers

We have gathered the answers to the most popular questions.

How do we call a customer when he/she opens an e-mail letter?

With this option, the newsletter mail-out becomes operant and more efficient, because you can contact the customer at the message-opening stage and help to conclude a deal.

How do we turn an interested user into a customer?

It is important to use any marketing tool, including a callback widget, in a reconciled and reasonable way – and ideally its operation should also be automated. In such a case, we turn it into an effective and simplified tool for interaction with the target audience. If you use such tools rationally, you can make the life of your company easier quite significantly and even enjoy the process of attracting customers.

How businesses lose customers

The CallUpper callback service team has prepared a series of interesting examples of how businesses lose customers only because users confuse one digit in the phone number that a business indicates on the site.

Why do I need a callback widget on the site?

In the modern world, the quality of communication is extremely important for both the company and the client. This is exactly the "bridge" that connects the two banks. You do not dare to go along the "bridge", which has the handrails broken, lacks several planks, and squeaks and swings with each step made, do you? Most likely, not, right?

How CallUpper recommends working with the lead scoring

Lead scoring is a methodology for assessing and ranking each individual lead according to the interest it represents for your business. In simple terms, this is a technique for segmentation of potential customers, who are in the sales funnel.

Increasing the online store sales with a callback button

Increasing the online store sales is a key task for any site owner. There is a multitude of options. The only thing is they have varying efficiency. If something worked out well for your friend, it does not mean it will work out well for you. Therefore, to solve the problem you need to thrash out a variety of options. And one of them is the use of a callback widget.

Customer testimonials

Our satisfied customers will speak for us.

We have an online store with an unusual product – eco-footwear made from hemp. And that is why attracting a customer is a complex and quite expensive process for us. Having analyzed all the promises of CallUpper, we have selected them for one elementary reason – everything they proposed to do is simple, both for marketing and for sales. Moreover, the most important thing is that everything works. Thanks to them, we are able to keep the attention of visitors and to sell more often than we did before.

Tatyana Krause

CEO at ZenStyle

Guys have perfectly thought of everything in CallUpper – from the first contact with the site visitor, a gathering of the necessary contact information, and up to subsequent interactions with a warm lead. Our number of non- returnable visitors has gone down now, while the number of customers is still increasing – not least because of your service! We recommend this service to everyone who appreciates simplicity and efficiency, as well as their time, money, and customers!
