How to Mail Sourdough: 2-Day Rule and Postage Cost
Pack, time, and price a mailed sourdough loaf so it arrives whole and still worth buying.
On this page
What to remember
- Cool the loaf all the way before it goes in the box.
- Wrap in paper, then a bag, so the crust does not sweat.
- Pad every side. If it moves, it breaks.
- Mail early in the week so the box does not sit.
- Add the box and the postage to the price, not to your pay.
Mailing bread is not the same as handing it over at the market table. The loaf has to survive a truck, a sorting room, and a doorstep, and it still has to look like something she paid for. Once you know how to mail sourdough, you can sell to customers two states away instead of two streets away.
Choose a loaf that can take the trip
A firm crust travels better than a soft one. Skip anything with a wet glaze, a fresh fruit topping, or a loose crumb that will smear against the wrap. The loaf you mail should be the one you would still be proud to hand over after three days in a box.
Size matters too. A long loaf fits a long box with less empty space than a round boule, and less empty space means less movement. If you sell mostly round loaves, look at the box sizes you can buy before you promise a shape. Our guide to how to ship sourdough walks through the box choices.
Think about the weather at the other end. A loaf mailed into a hot state in July has a harder trip than the same loaf mailed in October. If you sell year round, offer a slower, cheaper option in the cool months and skip mailing in the worst heat.
Wrap and pack the loaf, step by step
You do not need special supplies. Paper, a bread bag or plastic wrap, tape, a sturdy box, and something to pad with will do. Packing material you already have in the house is fine as long as it does not smell.
Cool the loaf completely
A loaf that is even a little warm will fog the wrap and arrive soft. Wait until the bottom is cool to the touch before you start.
Wrap in paper, then in a bag
Paper first lets the crust breathe. A bag or a layer of plastic over the paper keeps the loaf from drying out on the trip.
Tape every fold
Tape the seams so the wrap cannot shift and rub the crust bare in transit.
Pad the floor and the walls
Put a layer of padding in the bottom of the box, then fill every gap around the loaf.
Cushion the top
Leave padding above the loaf so the lid does not press down on the crust.
Seal it and mark it
Tape all the seams, write the address on one side, and write the bake date on the wrap inside.
Shake the closed box. If you can hear or feel the loaf move, open it and add more padding. A box that rattles is a box that arrives in pieces.
Time the drop off so the box does not sit
Mail early in the week. A box that goes out on a Friday can sit in a facility until Monday, and that is two extra days on a loaf with no preservatives. Ask for the current delivery estimate for the service you pick, and give your customer that estimate instead of a guess.
Holidays are a busy week for every carrier. If a customer wants a loaf for a holiday table, mail it the week before and tell her how to store it when it lands.
Drop off at a staffed counter when you can, and ask for a receipt. A receipt is your proof if the box disappears.
Price the box and the postage into the order
Shipping is a cost, not a favor. Add the box, the padding, the wrap, and the postage to the price of the loaf before you quote her a number. If you pay the postage out of your own pocket, you are paying her to buy your bread.
For example, say you sell a loaf at $12, the top of the $6 to $12 range in our guide to sourdough loaf pricing. Your ingredients and your labor come off your own costing sheet. Overhead is the easy part: Brevl is one flat $20 a month with no cut of your sales, so mailing 10 loaves that month costs $2 a loaf. Your margin is $12 minus ingredients, minus labor, minus $2. If that number is not worth your morning, raise the price or stop mailing.
Buy a small kitchen scale if you do not have one. You need the packed weight, not the loaf weight, to price the postage. Guessing high costs you a sale, and guessing low costs you money at the counter.
Decide one shipping price for each region you sell into, and put it on your order form. Quoting a new number for every customer eats your evening and invites haggling.
What to put in the box besides the loaf
A small card with the bake date, the flavor, and how to store it makes the box feel like a gift instead of a shipment. Add your shop name and how to reorder. Skip anything that can leak or scent the loaf, like a loose bar of soap or a scented candle.
If you sell starter too, keep it in its own sealed jar inside a second bag. A cracked jar in the same box as a loaf means you replace both.
Mistakes that cost you money
Most mailing problems are packing problems. Fix the packing and the refunds drop.
What to check before you promise a date
Check the current mailing rules for food with the carrier you use before you take the order. Check your state’s rules for selling from home too, and ask whether shipping out of state changes anything for you. Our guide to starting to sell sourdough from home covers the first steps.
Then test it. Mail one loaf to a friend in another state, ask her to photograph the box before she opens it, and change what failed. One test box costs less than a week of refunds.
Keep a note of what you mailed, when, and what it cost. After ten boxes you will know your real shipping number instead of guessing.
If you sell more than bread, the same packing rules apply to cookies, muffins, and cakes. The craft guides cover wrapping and boxing for each one.

Common questions
Can I mail sourdough in a flat rate box?
You can if the loaf fits with padding on every side. Measure the loaf before you buy the box. A flat rate price only helps when the box is full, so compare it with the price of a plain box at the weight you are actually mailing.
How long does mailed sourdough stay good?
That depends on the loaf, the wrap, and the weather. A tight wrap and a cool trip help. Tell your customer the bake date and how to store it when it lands, and mail early in the week so the box does not sit in a facility over a weekend.
Can I mail sourdough in a padded envelope?
No. A padded envelope protects a cookie, not a loaf with a crust. Sourdough needs a rigid box with padding on all six sides. If the box can flex, the crust will crack at the corners before it arrives. Spend the extra on a real box.
What if the loaf arrives broken?
Ask for a photo before you decide anything. If the box was crushed, the packing needed more padding, and you should refund or replace without a fight. Then change how you pack the next one. One refund is cheaper than a customer who tells her friends you ship badly.
Do I need to tell my customer it is coming?
Yes. Send the drop off date, the service you used, and the bake date in one message. A customer who knows when the box lands will not open a refund request on day two. Add how to store the loaf and how to reach you.
