If specifically request I will reply to anjy QSL

For example I do not normally use eQSL

however many others do, eQSL is not accepted for DXCC awards

however many use it to pursue other awards even those provided by eQSL itself

So when I get an email request to upload an eQSL I Do so and I usually add to the email reply a polite note reminding them if they later on pursue ARRL Awards, those eQSL's are invalid.

I prefer LOTW
it saves both parties $ and is efficient as compared to snail mail

and I no longer (as of 5 years ago) have envelopes at the Buro

So those sent that way I never see, they go into the trash.

I also prefer SASE however I do QSL the few I get with no SASE

out of courtesy

So when you say a picture sent by email of a QSL is invalid

I understand you mean it is not valid for awards you consider

it may be a valid QSL to the sender's needs or wants.

cheers!
