How to Send Thank-You Cards to Customers and Clients

The short version: Mailing thank-you cards to customers or clients costs $1.99 to $5.41 per card all-in, and the swing is format — a printed postcard at $1.99 against a folded card in an envelope at nearly three times that. Postage is the hidden $82 on a hundred cards, because half these vendors quote without it. DIY looks cheapest on materials at roughly $1 a card, and stops being cheapest the moment you price the full working day that a hundred cards takes.

Every price below was verified against the vendor's own live pricing page on July 27, 2026, with the Simply Noted figures re-read on October 28, 2026, and postage reflects the USPS rates effective July 12, 2026. Vendor pricing moves — sources are linked so you can re-check.

What does a client thank-you card cost per unit?

Three cost models, on an all-in basis — printing, addressing, postage and mailing included.

DIY is the number that misleads. At $1 a card in materials it is unambiguously the cheapest line item, and at 100 cards it consumes a full working day of somebody's week. Price that hour at anything above $12 — well under any real fully-loaded cost — and the service wins outright, before counting the cards that never get sent because the box sat on a desk through Q4.

What 100 client cards actually costs at each vendor

A real 100-card batch at the main print-and-mail and handwriting services, all-in — cheapest first, DIY last for comparison. It isn't every vendor in the market; it's the ones publishing a price you can check.

Format is part of that spread, and it's the column most comparisons leave out. ShipNote mails postcards — no envelope, so the note is readable from the mailbox, and postcard postage is $0.65 rather than $0.82. Postable and the handwriting services mail folded cards in envelopes. If what you're sending needs to be private in a client's mailroom, that difference matters more than the price does. If it's "thanks for the referral," it doesn't.

Two other things explain the spread. Postage often isn't in the quoted price — Postable's $4.59 and Handwrytten's per-card rates both add USPS postage at checkout, $82 on a hundred cards. And the handwriting services' cheapest rates are gated: Handwrytten sells at $3.75 retail with no plan, but its $1.19–$1.99 tiers need a monthly plan from $449, so a business sending one batch a quarter can't reach them.

How do you personalize 100 cards without a mail merge?

Personalization is where these projects die. It shouldn't be.

Write the message once with a placeholder. Compose a single message with a client token — [CLIENT] — and each card prints with that person's actual name. One message, not a hundred, and every card still opens with the client's name. That is the step list-upload mailing services leave out: Vistaprint's postcard mailing service takes an address list with no message column, so every card carries the same words.

Then edit the ones that matter. The dozen accounts that deserve a specific sentence get one; the rest take the template.

Feed it your existing list. Paste the CSV rows, a column of addresses, or text copied out of email signatures — the extractor works out which field is which, so there's no column-mapping step. Every address is then checked against USPS records before anything prints, which catches the two things that actually go wrong at volume: bad formatting and addresses that won't deliver. Anything USPS can't confirm is shown to you by name before you pay.

One practical limit worth knowing before you plan a mailing: the paste box takes a few hundred rows at a time. If you're sending more than that in one go, split it into batches or get in touch first.

Sending thank-you cards to customers: what changes?

Clients are usually a few dozen accounts you know by name. Customers are more people, each worth less to you, so the real question is which of them get a card.

• Pick a trigger, not the whole list. First orders, repeat buyers, orders over a set value, or everyone who left a review. A card on every order is a cost per order; a card to a chosen group is a budget you can cap.
• Price it against the order. At $1.99 a card all-in on 10 or more, set the trigger where that is small next to what the customer spent.
• Start from your order export. Paste rows from your store's order or customer export the same way as a CRM export: the extractor finds the names and addresses, and one message with the same [CLIENT] placeholder covers every card.
• Send in batches. A weekly or monthly batch of the last period's customers keeps it to one sitting, and 10 or more cards gets the $1.99 rate. Cards go out the next business day, or on a day you pick.

Printed or machine-handwritten?

Both are legitimate; they're different purchases, and the honest case for handwriting is stronger than most comparisons admit.

Machine-handwritten cards are written in real pen by a robot arm and arrive in an addressed envelope. The envelope is a real part of what you're buying — a hand-addressed envelope gets opened, and if the card's job is to be opened, that's worth roughly double the price and the minimums that come with it.

Printed postcards trade the envelope for the message. Nothing to open, and the note is visible from the mailbox — wrong for anything confidential, fine for "thanks for the referral." For a batch where the content is the point, a specific reference to the project or the order, printing puts the money into the message rather than the ink delivery.

What a business buyer should check before ordering

The things that decide whether this works operationally, which pricing pages rarely cover:

• How you pay. ShipNote is card payment through Stripe, with a receipt emailed on your order confirmation carrying the order number, date, total and payment method. There's no invoicing, PO flow, or net terms — if your business can't buy on a card, that's a blocker.
• Whether our name is on the card. By default a ShipNote postcard carries a small "via shipnote.co/card" line on the back. Removing it costs $0.10 a card, so a hundred unbranded cards is $209 rather than $199. Worth pricing in if these are going to clients.
• Turnaround. Cards go out the next business day and most arrive 4–7 business days after that, so work back at least a week from when you want them landing.
• What happens to a bad address. The address check flags most problems before you pay, a card we can't address isn't charged for, and a card we still can't send is refunded rather than billed — worth confirming with any vendor you use, because not all of them do it.
• Volume pricing. ShipNote's rate floors at $1.99 from 10 cards and doesn't drop further. Above a few hundred cards, services with deeper tiers get competitive — Postable discounts above 200, Simply Noted keeps stepping down. Worth comparing at your actual volume rather than at 100.
• Your client list. It's used to fill your order, and the text you paste also goes to OpenAI, which turns it into structured rows. We keep a record of that request for a limited window and then delete it. The order itself — names, addresses and your message — is kept so we can answer questions about what we mailed, as are our address-verification records, and a list you entered but never paid for is kept too, because the order record is created when you reach checkout. We delete any of it on request. All of this is set out on our privacy page. If your list is sensitive, ask any vendor what they keep and for how long before pasting it.

The short answer for most businesses

If you're sending under a few hundred cards a few times a year, a no-minimum print-and-mail service is the right shape: no plan to carry between batches, no credits expiring, no minimum forcing you to buy 100 when you need 60. That's what ShipNote's business thank-you cards are for — write one message with a name placeholder, paste the list, edit the handful that need it, and every card is printed, addressed, stamped and mailed. $1.99 per card at 10 or more, postage included, usually in the mail the next business day. The same client list makes the December card too: business holiday cards with your logo go out from one upload, and you can order now and pick the day they mail. For the holiday version of this comparison, see how to send Christmas cards to clients, which prices the card companies that mail them.

If you're sending thousands a month, or an envelope is genuinely the product, the plan-based services above will serve you better and we'd rather point you at them than pretend otherwise.

Thank-you card FAQ

What does it cost to send thank-you cards to customers or clients?

All-in — printing, addressing, postage and mailing — expect $1.99 to $5.41 per card from a print-and-mail service. The spread is mostly whether postage is inside the quoted price and whether the card comes in an envelope. Machine-handwritten cards sit in the middle of that range; Simply Noted sells them in 100-card credit packs — its $497-a-month unlimited plan only pays off far above this volume — while Handwrytten sells at retail with no plan at all.

What's the cheapest way to send 100 client thank-you cards?

A print-and-mail postcard service at around $199 all-in for 100, postage included. DIY costs roughly $100 in materials and stamps but adds about eight hours of staff time — at any realistic fully-loaded hourly rate, that makes DIY the more expensive option for a business.

Do clients receive a card in an envelope?

Not from every service, and it's worth checking. ShipNote mails 4x6 postcards — no envelope, so the message is readable in transit, and postcard postage is $0.65 rather than $0.82. Postable and the handwriting services mail folded cards in envelopes, at up to nearly three times the price.

Can I send cards from a CRM export or spreadsheet?

Yes. Paste the CSV rows, a column of addresses, or even copied email-signature text — the extractor works out which field is which, then every address is checked against USPS records before printing, so problem addresses are flagged before you pay.
