Sample Letter Informing Clients That You’ve Switched Companies

If you are planning to switch companies, you need to inform your clients in a succinct email letter. Whether you resigned, found a new job, or transferred to a new internal position, it is unprofessional if you simply ditch your clients without saying a proper goodbye. In your letter you want to give a brief description of why you are leaving your client and introduce the new contact person. Keep in mind that you want to make the transition as easy as possible for the client.

Put yourself in his or her shoes and try to think about their top priorities and how they will be impacted by your move. In addition to writing a great letter, make sure to update the person who will be replacing you. Small steps to ensure a smooth transition will only help you in the long run. Below are two sample letters letting clients know that you will no longer be their main point of contact.

Sample Letter Informing Clients of a Resignation

Dear Client,

I am writing this letter to officially inform you that as of November 12, 2014, I will be resigning from Radeon International and starting work at Intromed Incorporation.

Taking such a huge step has without a doubt been one of the toughest decisions I’ve had to make in my life. It is incontestable that without your continuous contributions and buoyant generosity within our programs, the company could not have possibly maintained its contemporary rank in the market, nor could it have sustained such astronomical success.

Thank you for providing me with the opportunity of assisting you, as well as flourishing and expanding our company. I will be available by phone at 111-414-6666, or via e-mail at

Yours faithfully,
John Doe
