Mail merge for postcards

[Nick Hughes]

My partner and I are newbie investors, just about to be sending out our first direct mail campaign to absentee owners. Will be sending out ~1000 pieces a month, beginning with postcards and then cycling through various other mediums.

Question is... how do you go about using mail merge for a large order of postcards? The printing companies I've spoken to would require a huge custom order to be made ($$$) with each postcard being a unique file upload with the mail merge info, and do not offer mail merging services of any kind. How does everyone go about using mail merge to personalize their mailings without breaking the bank with the printing company?

Any help is appreciated!
