I want to introduce my new firm (pharma). So I want to write a letter to my client. I want a sample letter to introduce my firm .

Are they existing clients you already serve and merely have a new company added to other companies you are selling for ?

Have you changed companies and want to tell past customers that you are working somewhere else?

Are you wanting some direct mail to people who don't know you at all, just trying to get them to buy from you.
