Except you can't sign a message with JAXX and when you send the micro tx, it'll change your address rendering the link useless. Use Electrum to sign, easiest method unless you can still sign messages in mycelium.
The link wouldn't be useless because you can send your BTC back to your linked address. Actually, that is the general case when you do a micropayment, the remaining BTC is sent to a change address and you should send them back to your linked address.
