Just send a letter with a copy of your notice.
I recommend a separate letter for each notice.
Include each letter and notice in the same envelope.
Make sure you identify each LLC on the appropriate letter (using the EIN).
Also make sure you keep a copy of the letters and notices for your records as well.
And the most important piece, is to send certified mail return receipt requested.
