I do this twice a month...

"Yes I'm almost done" - then I go to actually read the email and I see that all the specs are in a WeTransfer link that expired a month ago. Or in a Google drive link where's I don't have access rights. Fucking google drive links, clients always copy their link that they received and forward it to me. When I get a Google drive link there's a 85% chance that I don't have the access rights...
