How to Embed url in email notification form?

[solved]
partially anyway:

<a target=”_blank” href=”https://www.paypal.com/xclick/business=mypaypal@email&item_name=My_deposit
&amount=200.00&no_note=My_deposit&tax=0&currency_code=USD”?? > Paypal link

Problem remains that for some reason in the email form ‘&currency_code=USD’ is filtered and corrupted

FIX prepend double &: &&currency_code=USD
