적어 두세요 means please write it down and keep it that way for later.
The pattern -아/어 두다 adds the idea of doing something in advance or leaving it done for future use.
So:
- 적으세요 = write it down
- 적어 두세요 = write it down and have it ready/saved for later
In this sentence, that nuance is important because contact information is something you may need later.
Because 적다 and 두다 are separate verbs.
- 적다 = to write down
- 두다 = to put, leave, keep
In grammar, -아/어 두다 combines with another verb to mean do something in advance and leave it done. Even though it works like one grammar pattern, it is often written with a space because 두다 is still originally a separate verb.
You may also sometimes see forms like 적어두세요 in less strict writing, but 적어 두세요 is the standard spacing.
