Gracias. Merci. Danke. Obrigado. Grazie. However you say it, ‘thank you’ is one of the most important phrases in your vocabulary and an effective tool for your sales team to build relationships AND revenue. In this post, I’m expressing why you should tell your clients and customers how much you appreciate them and showing you how with a simple message formula and 8 example thank-you notes. (Including some proposal- and RFP-specific ones.)
