A dialogue, not a monologue
Do not write long texts. They are difficult to read and can be seen as spam. Turn a long monologue into a dialogue. Even if a person is interested in what you have to offer, they may not have time to read it because it is long. They may decide to read it later and then simply forget about your message. It is better to divide your product or service into short messages and ask questions. In this way, you gradually engage the customer.
You need to find out how the person will use your product or service. Ask what their interest is, why they need it. Find out all the details. Even if you think you understand your customer and know what they need, try to ask a question that will confirm your guess. Once you have done this, you can start to build your presentation automatically. If you suddenly find that you don't have the product your customer needs, you can use your knowledge of their needs to suggest other options that might meet their requirements.
The right price presentation
It often happens: you make a presentation, quote a price and the client disappears. You even ask questions afterwards and they don't answer. What can be the solution? State the price and ask an engaging question. For example, find out if the chosen product is suitable in terms of features, or if the customer would like a different configuration. If the person wants to explore other options, make a new presentation.
Don't use templates
You may have read that to make your job easier, you should create templates for communicating with your client. So you've made them up and you answer questions with standardised phrases. It is good to use the name of the person you are talking to, but sometimes you do not even address the client. That's wrong. You must address them by name. It is also necessary to emphasise the client's situation. This will make a positive impression and build trust. Do not ignore questions and information from the person you are talking to and focus only on the phrases in your templates.
Combine Messenger communication with calls. Even if you're chatting with your customer, it's worth getting them out of there and clarifying some details on the phone. If you feel that you need to find out more information or, on the contrary, give them more data to reinforce your communication, then call. But do not do it without warning, first show them the advantage of such communication. For example, you ask a question about the customer's past experience and he replies that he had some negative experiences before. Then say that in order to avoid a negative outcome, some points need to be clarified over the phone and offer to call. This shows initiative and care, as your aim is to understand the situation as well as possible and take the customer's wishes into account as much as possible. In this way, you will achieve multi-channel communication, making it even more effective.
Voice messages are a common means of communication in messengers. However, not everyone is happy with them. If you want to use voice messages to communicate information to your customers, ask them first if they think it is appropriate.
