Why the mail-merge route feels like work

The classic way to print address labels is Word mail merge plus a downloaded template file — and it works, right up until the printer margins shift, a field overflows its box, or the template you found does not quite match the sheet in your hand. The spreadsheet-first route skips all of that: keep the addresses in Excel, and let the tool worry about the grid.

SeatMark reads your list directly in the browser. Choose the actual adhesive sheet you bought — the die-cut layout is already stored — and every label previews with real data before you spend a single sheet.

Step 1 — Get the list into shape

One recipient per row, headers in the first row. A name column plus address and phone columns cover the common layouts; extra columns just ride along.

  1. Save or export the sheet as .xlsx or .csv.
  2. Split multi-line addresses into one column if you can — the layout wraps it for you.
  3. Check for empty rows between entries; they become blank labels.

Step 2 — Pick the sheet model, not a grid

Open the paper library and find your sheet — Avery 5160 (30 address labels per sheet) or 5163 (10 shipping labels) are both there, alongside dozens of common die-cut layouts. The moment you pick it, the rows, margins and gaps lock to the real die-cut. You never measure anything.

Step 3 — Choose a layout designed for that sheet

Every sheet model ships with dedicated templates — address labels in several styles, return-address strips, fragile marks. Pick one and the preview fills with your real rows immediately. Long addresses shrink or wrap instead of silently overflowing the cut line.

Step 4 — Print on the adhesive sheet

Export as PDF and print at 100% scale on plain paper first if you want a trial run, then on the adhesive sheet. Peel and stick — no scissors, no misaligned cuts. If your printer drifts a fraction of a millimetre, run the built-in calibration once.

Common pitfalls

  • "Fit to printable area". Scaling by even 2% shifts every label off its die-cut — always print at 100%.
  • Wrong sheet model. A 5160 grid printed on a look-alike sheet lands half a label off — match the model, not the look.
  • Mixed-length addresses. Check the longest row in preview before printing the batch.
