Between 1/2 & 1/3 are by email and almost almost all of these pay online. The processor sends out several checks together in an envelope. The first time, I pulled out a check & then started to throw the envelope in the trash when I noticed it felt heavy. Two more checks inside. I am in Florida with a lot of seasonal residents, so I communicate a lot by email. Back when we were having all the hurricanes, I sent out weather updates because they were "freakin' out" & kept calling me.
