Complimenting other companies on the service, they provided you is essential if you want to get client appreciation for the products or services you delivered. Goodwill and favorable treatment (or pricing) may result from it.
Sample 1: Letter complimenting a venue where you hosted a business event
Dear [Name of Recipient],
On behalf of our company, [name of company], I would like to extend my gratitude to your hotel for the successful event that we had on [Date of event]. The [Name of Event] is a very important [annual / monthly / occasional] event for our company and it would not have been nearly so successful if it hadn’t been for your superb service.
You went above and beyond our expectations and we really pleased with everything. Your staff were a credit to you and nothing was too much trouble. The food too was excellent.
We received a lot of compliments for the event and much of it was directly related to your hotel.
Thank you for making the event a complete success and you can be sure that we will be booking more events with you in ther future and we will of course refer other businesses to you when the opportunity arises.
