Writing a sales proposal letter is a great way to get new business and let other businesses know what kind of services you offer. This letter is a chance to tell other companies what you have to offer and why they cannot live without your services.


Decision Making Party

The key is to make sure that you address this letter to the decision-making party rather than just as a random piece of junk mail to be tossed aside. Because you are trying to drum up new business, you want to make sure this letter is perfect.

Every word must be spelled correctly, and the grammar must be accurate. The language used in this letter could be the difference between getting a new client and losing business. If the letter is written poorly, it could be of great detriment to your company.

Proper Formatting

Start the letter with the proper formatting, including the date, address of the company, and the name of the person who has the authority to make decisions.

Always use a formal name like Dr. Carrie Snyder and not an informal “Dear Carrie.” The reason behind this is that you want to recognize their hard work and the accomplishment of their position.

Opening paragraph

The opening paragraph needs to be captivating and let the readers know why they need your services.

Choose the opening statement well because it could mean the difference between the letter being read and one that is put in the trash.

It’s always good to start out by telling people how they can save money. In these economically downtrodden times, saving is the first thing on many people’s minds.

Second Paragraph

The second paragraph of the proposal letter for digital marketing should allow business people to see the benefit of your services.

Show them how your service can save them money and increase their business. Break it down into details about how they cannot live without this product or service.

By presenting your company as having a problem-solving opportunity, you will get the reader’s attention and make them think about what you are offering.

Another Trick

Another trick in writing a letter of this nature is to break it down into small paragraphs. People tend not to want to read a big, long paragraph. Short paragraphs work best.

Be sure to include your company’s qualifications. If your services require them to come to your office, describe how adequate and posh your facilities are. 

Talk about the employees that work there and how well trained they are. By providing a brief history of the company and its key employees, the entire organization appears more capable of carrying out what is stated. Here is a sample proposal letter.
