It is never an easy time when a business is being closed. There are so many people who are attached with it. Some of them are losing their means of livelihood and others are losing a significant part of their products or services.
It is not easy to announce that the business is being closed for any particular reason. One of the best ways to do this is to send an email out to the stakeholders and let them know about this development. Make sure this email is sent well in advance of the actual closing date so everyone can make adjustments that might be required.
Start the email with the unfortunate news that the business will cease to continue operations from a specified date. Keep this paragraph brief.
In the next paragraph, shed some light on the business as well the as the relationship it maintained with the addressee and how much the company valued it.
In the end, wish the person all the best in his or her endeavours and conclude the email.
