Typically when writing a polite and formal message or email; a longer sentence will sound more courteous and gracious than a two word reply.
There are innumerable ways of writing a polite acknowledgement, or a thank-you note. Change the adjectives with ones that you feel more comfortable with.
You can use the verb, grasp, instead of understand to say you comprehended something fully, and you won't easily forget or be confused by it again.
