Hi,
please try to upload vector file of your logo.
thanks.
regards

I uploaded the files. Many of them, but use what you need.

Thank you!

Hello,
for EDDM mailing, what size postcard do you need? The size specified in the brief isn't an approved EDDM size.
Thank you!

Looks like 6.125" x 9". That seems to be the postcard size I've been receiving in the mail. But the post office website states 6.125" x 11". Either one will do.
