Pick your mailing date first, then work back through four office tasks: copy, list, proof and release. Allow time for address checks, proof approval and print scheduling. If you want a January mailing, start the quote and list review before year-end. Confirm the actual dates with your vendor.

Put the target on paper
Write down whether your target means ready to print or handed over for mailing. Give the vendor that exact target so both sides plan the same job.
Work back through four steps: approved copy, checked list, print proof and mailing release. Assign a person to each one.
Leave room for an address fix
Build a follow-up task for returned pieces. Keep the task open while addresses still need work.
Keep mailing dates apart from HazCom dates
OSHA's updated HazCom schedule concerns workplace labels, programs and training. It does not set the date for a household safety mailing. Give those projects separate names on the office calendar.
Questions and answers
Is January a legal deadline for all retailers?
No. January is only a planning example, not a legal deadline. Ask your reviewer which dates apply to your business.
What should I ask the printer first?
Ask when the list and proof must be approved to meet your requested mailing date.
Should the mailing wait for every late address change?
Set a list cutoff and a separate follow-up process. Have the office lead approve how later changes are handled. Ask the office lead to name who reviews new accounts or changed occupants after cutoff. Record the change date in the account file and pass unresolved recipient questions through your approved process. See who should get a propane Duty to Warn notice for recipient review.
What date belongs in the finished file?
Record the actual mailing date shown in the mailing evidence, along with the list and copy version used.
