If you have to write a business email letter you have to remember to use a professional and formal tone. It is also important to keep things short but not to skip any important piece of information that would make it easier for the receiver to understand your message. You don’t have to write long letter, but it is a must to write in a clear and easy to understand way, something like:

Sample Business Email Letter:

Subject line: (name of the event)

Dear (name of the receiver),

I am writing this email to thank you for the assistance you offered us regarding the planning of the annual conference. Your help with logistics, multimedia presentations, meeting arrangements, travel coordination, and overall organizing of the event made a great difference in the outcome of the event and all your hard work is appreciated by us.

I am really grateful for your help and I can assure you that because of the efficiency of your work and your professionalism we will contract you for next year’s event as well. We would also like to thank your staff for their hard work and we would like to let them know that their experience and professionalism didn’t go unnoticed at the event. We would like to work with such professional people in the future as well.

In the meantime, we would be happy to offer you a recommendation. In case there is anything else that we can help you with please don’t hesitate to tell us.

Best regards,
