You still have to remember what you're doing and make it very clear
in the letter.
Are you thanking the person, are you answering a question,

Language
Again, you don't want to use very serious language in an informal
letter or email; you don't want to use too many formal or complex words
because that's not how we usually speak to friends and family.
With our friends, we're usually very casual and relaxed.
For example:
I just wanted to say thanks for helping me out last week.
In a formal letter, you would write
I'm writing to express my appreciation and gratitude for your
assistance with last week's matter...
Notice the different feel of the two sentences. One is very casual;
one is very formal.
Another example:
Should you require any further information, please do not hesitate to
contact me - formal.
Versus
Let me know if you need anything else - super casual.
To make your letter look real, the best thing you can do is ALWAYS
rely on your personal experience.

for a job. Here are some examples of formal and informal words
with the same meaning,
