Ask the customer which medium they prefer talking through: Text, Email or call.

Ask if they are in a good place and have time to communicate. Do not assume customers time is available they could be pressed with something else and respond later.

You need to go straight to the point and explain the information you want to pass across, do not divert from the main point.

Use good language and etiquette when communicating. Do not use inappropriate language even if the customer gives you a go ahead always maintain your professionalism.

Do not promise on what you cannot deliver, when dealing with customers always be sure when you say 10 am or 2pm make sure you are able to deliver on that exact time or before. If something occurs that can delay you ability to deliver always communicate one hour before to allow the customer to make adjustments on their schedule.

Ask questions to ensure your customer has understood you, give them an opportunity to ask questions on areas of concern.

Remember to say thank you or thank them for their response whether it is positive or negative. Some customers may not be in a position to purchase a product or service but due to good service they will refer friends and colleagues who could make a purchase. Always leave a good impression of professionalism on whatever you do.

Always respond on time, delaying can be assumed as lack of seriousness by the customer.

Best of luck as you engage with customers.
