Questions creators ask us

Who handles sales tax?

We do. Sendero Origen, LLC d/b/a Good Post Co is the seller on every membership, so working out sales tax, charging it, filing it and paying it to each state is ours. We register in any state where the law says we have to. You never register for sales tax or file a return for your club.

What does it cost?

10% of each payment, before sales tax, and that includes the card fees. Once a club’s sales pass $5,000 in a calendar month, the fee on the rest of that month’s sales drops to 7%. There is no monthly charge and no setup fee.

The one cost passed on is the fee when a subscriber disputes a charge with their bank, at what Stripe charges us ($15 today).

Who deals with refunds and disputes?

We do. Because we are the seller, we decide refunds under our Cancellation & Refund Policy. When a subscriber disputes a charge with their bank, we answer it with what we hold: the receipt, what they agreed to at checkout, the address the mail went to, and the date you recorded it as sent. Recording each mailing promptly is the most useful thing you can do to win one.

When a refund or a dispute goes against a payment, your share of that payment comes back out of what we pay you, and we give up our fee on it too. The one cost passed on is the bank’s fee for a dispute, at what Stripe charges us ($15 today).

How and when do I get paid?

After each mailing, straight to your bank, through Stripe. Stripe checks who you are and holds your bank details; we never see them.

When you record a month’s mailing as sent to at least 90% of your list, what your subscribers paid for that month goes out in our next payout, usually within the week. So in practice you’re paid once a month. A year, a prepaid run or a gift paid up front is paid out a part at a time, one part for each month you mail. The money follows the letters, which is how we can promise subscribers a refund for any letter that doesn’t come.

Is there a limit on a brand-new club?

Until its first mailing is recorded as sent, a new club can take up to $2,500 in sales. After that there is no limit. It protects subscribers, and every other club, while a new club proves it mails.

What can I sell?

Monthly memberships, a year paid up front, and prepaid runs of 1, 3, 6 or 12 months. Any prepaid run can be sold as a gift: the buyer pays, and you post to the person it’s for.

You set your own prices, between $5 and $50 a month (a yearly price works out the same per month). If you need something outside that, ask us.

Can I have tiers?

Yes. Each tier is its own monthly plan with its own price and description, such as “Letter” and “Letter + print”. You can list three on your application, and we add more if you need them.

When you open a month, your studio counts how many of each tier you’re sending, shows each subscriber’s tier, and prints labels and envelopes one tier at a time, so packing stays simple.

How often does mail go out?

Once a month, on a day you choose (the 1st to the 28th). You also choose the last day to join for that month’s envelope; anyone who joins after it starts the month after.

Can I take sign-ups before my first mailing?

Yes. Someone who joins monthly or yearly more than a month before your last day to join for your first mailing pays nothing that day. Their first payment is taken on that last day to join, just before you post, and the checkout page tells them the date. Anyone who joins in the month before it is charged when they join, as they will be after you have mailed. Either way, nobody pays for a month with no letter in it.

Can subscribers pause, skip or cancel?

Yes, from their own account, with no password to remember. Anyone can skip a month. A monthly member can pause, which stops the payments and the mail until they start again. Cancelling is one click, and a letter they’ve already paid for still goes out.

Can they track their mail?

Letters don’t have USPS tracking. You can turn on an email that tells each subscriber their mail is on its way as soon as you record the month as sent, and gift buyers can get one too.

Can I email my members?

Yes. In your studio you write an update, send yourself a test, then send it now or schedule it. It goes out from your club’s name to members who said yes at checkout, and to followers: people who signed up for updates on your page and confirmed by email. A short note before each mailing, with a sneak peek and the last day to join, works well.

Every email has a link to stop them, and stopping never touches a membership. There is no tracking: no opens and no clicks. You see how many were sent, how many didn’t arrive and how many people stopped. You can send up to 4 a month and 1 a day, which protects the address every club’s email comes from. We read a club’s first update before it goes out, and any update with something risky in it, such as a street address or a short link. Replies come to us, and we pass on anything meant for you.

It’s part of the 10%. There is nothing extra to pay.

Do you add tracking or ads to my pages?

No. There are no analytics scripts, ad pixels or trackers on any page your subscribers see, and we never sell their details.

Can people outside the US subscribe?

Not yet. We plan to add Canada, Australia and New Zealand, for envelopes that hold only letters and other paper you read, because objects in an envelope going abroad bring customs and tax with them.

What do I see in my studio?

Your active subscribers, who’s new this month, who cancelled, whose card failed, and who’s ready for this month’s mailing. A payments statement for each month, your payouts, and a returned-mail log.

You can download your whole list, with addresses, any time. It’s yours, and it stays yours if you ever leave.

Can I cap my club?

Yes. In your studio, or on your application, you choose no limit, up to a number of members, or “not taking new members right now”. When every spot is taken, your page says the club is full and stops taking sign-ups by itself. Nobody who is already in is ever touched. You also choose who keeps a spot: members who have paused, members whose card payment failed, and members who have cancelled but still have letters coming.

A full club can offer a waitlist instead. People join with their email address and confirm it. When spots open, we email the waitlist for you: a few people at a time in the order they joined, or everyone at once, or nobody until you press a button, as you choose. Nobody hears more than once every two weeks, and the first to pay gets the spot. You can also show “3 spots left” on your page, always or only when a few are left.

It’s part of the 10%. There is nothing extra to pay.

Can I use AI to help make my mail?

Yes. We don’t check or monitor whether creators use AI. We ask you to tell your subscribers when AI made a meaningful part of what’s in the envelope, such as the writing or the art. Spelling and grammar, a logo or admin work don’t need a mention.

To make that easy, your studio has an optional box under Club page: “Some of what I send is made with help from AI”, with room for a few words of your own. If you tick it, your page says so in a plain line near what comes in the envelope. It is your own statement. If your club has its own website, tell your subscribers there instead. There is nothing extra to pay.

Can I take my list with me?

Yes. Your studio’s Exports page has everyone who has ever subscribed, with their addresses, as a spreadsheet, and a mail-merge list for each month. Your updates list and your waitlist export too. Download them whenever you like. The list is yours, and it stays yours if you ever leave.

What can I print?

Address labels (Avery 5160, 5162 or 5163), return-address labels (Avery 5167), and envelopes printed directly: #10, A7 for 5×7 cards, 6×9, A6 for 4×6 photos, A2, #6¾ and 9×12, plus the address side of a 4×6 postcard. You can also download a mail-merge spreadsheet.

Need a size that isn’t there? Tell us at support@goodpostco.com and we’ll add it.

Do I need my own website?

No. We host a page for your club with your logo, colours, photos and words. If you already have a website, keep it and link to us for joining and paying.

Do I have to put my home address on the envelopes?

No. You can use ours as the return address: Good Post Co, with your club’s name on an “Attn:” line. Anything that comes back reaches us, and we let you know. Or use your own, if you’d rather.

What can’t go in the mail?

Most paper, art and small flat things are fine. Some things aren’t, such as perishable food, restricted plants and seeds, medicines, and anything sold with a health claim. The full list is in our Acceptable Use rules.

What counts as a letter at the post office?

A rectangular envelope from 5 to 11½ inches long and 3½ to 6⅛ inches tall, no more than ¼ inch thick and no more than 3.5 ounces. A letter-rate stamp covers the first ounce, and each ounce after that costs extra.

Most club envelopes fit: #10, A7 (for 5×7 cards), A2 and 6×9 are all letter size.

What makes a letter cost more to send?

The post office adds a nonmachinable surcharge to a letter its machines can’t sort. Usually that’s because the envelope is square or close to it (it has to be at least 1.3 times as long as it is tall), too stiff to bend, or lumpy, with something like a coin, key, pin or bulky wax seal making one spot thicker. Clasps, string, buttons and plastic envelopes do it too.

An envelope that’s short on postage can come back to you, or arrive with postage due. Your subscriber shouldn’t have to pay to receive a letter they’ve already paid for.

What if my envelope is thicker than ¼ inch?

Then it’s a large envelope (a “flat”), which costs quite a bit more than a letter. A flat can be up to 15 by 12 inches and ¾ inch thick, but it has to bend and be evenly thick: a bump of more than ¼ inch, or an envelope too stiff to flex, can be charged as a package instead. A 9×12 envelope is always a flat.

How do I get the postage right?

Before you buy stamps for the whole list, take one finished envelope, with everything in it, to the post office counter and ask them to weigh and check it. Then you know exactly what every envelope that month costs.

About Good Post Co

Who can start a club?

Anyone 18 or over who lives in the US and has a US bank account. Creators outside the US can’t sign up yet.

How do I start?

Fill in the application. It takes about five minutes and asks everything we need: your prices, tiers, posting day and first month. We read every one, usually within two working days. Once it’s approved, your studio walks you through the rest: the creator agreement, connecting your bank, and your club’s page. When you’re ready, you ask us to open, and we do.
