If you received a notice by email that you have a QSL in EuroBureauQSL, you can get it
by simply sending a SASE to the postal address of the
entry point in your country, which will forward by return mail to you.
Have a look at its website (link below), if that entry point has special conditions for members or supporters,
perhaps you might be interested in.
Seize the shipping of your SASE to send your replying QSL to the other ham.
If someone requests your QSL "via EURAO" or "via EuroBureauQSL", or you find in QRZ.com
the same instructions as "QSL info", or you wish to get his/her card,
it is enough that you proceed in one of the following ways:
check in the list below if there is in your own country an entry point to
EuroBureauQSL and send your QSL there,
otherwise send it to the entry point in the other ham's country.
You needn't to include anything else than your QSL alone (no SAE, no GS, no IRC).
If you have more than one QSL to different OMs/YLs, even in different countries, you can send them all together to
one of these entry points and they will be distributed accordingly.
