I made a notebook to keep track of which card I sent to which person. I like to send cards for all the holidays, plus birthdays, babies, congrats, yadda,yadda,yadda!

I made a spreadsheed w/ room to list the occasion at the top of the sheet and names down the side. I added checkboxes for multiple years next to the names so I can notate whether I sent something (if a card was received too). Has been working well for me.

I used some chipboard/cardboard for the cover, many yummy Bazzill & Prima colors, brads to match the Primas, black ink & embossing powder, assorted stamps, paperbilities letter tiles, font is mom's typewriter. Inside I used different heavyweight printed papers to make tabbed dividers. Originally I scored the cover and used posts for binding, but it didn't work very well. I recently swapped out the posts for binder rings. TFL!
