Dear Sir/Madame,
I have recently started a Travel agency business jointly with my brother. Can you please help me to create a marketing template email which I will send to as many people and companies. In the template I should introduce my Travel Agency, describe what services I am offering(which I have already prepared) and the advantages to book air-tickets and hotel packages with me. Thanking you in advance.

You wrote such a beautiful letter here. I am sure you can write an intro letter for the travel agency. Or Google introduction letter travel agency sample.
