Automate your gifting & direct mail effortlessly.
Create and schedule campaigns that deliver cards and gifts to your clients right when they matter most — birthdays, anniversaries, closings, holidays, or any date you choose.
All of the gift preparation, packaging, and mailing is handled for you, no matter the size of your contact list. And there are no minimum orders.
Make every gift unique to every recipient — at scale.
Import your contacts by spreadsheet or integration and each card or gift is personalized with the recipient’s name, so your mail always stands out.
It’s the hand-written, thoughtful touch that builds lasting relationships — without doing it by hand.
Track every response with dynamic QR codes.
Each QR code is unique to the person it was mailed to, so you get an instant alert naming exactly who scanned it.
Use those scans to trigger follow-up by text, email, and more — and finally see what your direct mail is doing.

What is Mailbox Engine?
Mailbox Engine is an automated client gifting and direct mail service. You choose who should receive a card, postcard, letter, or gift and when, and every piece is personalized with the recipient's name, printed, packed, and mailed for you — usually the next business day.
Who handles billing and fulfillment?
Memberships, billing, the sending platform, and fulfillment are provided through our platform and fulfillment partner. Mailbox Engine helps businesses choose a plan, set up campaigns, and get results.
How much does Mailbox Engine cost?
Memberships start at $99.99 per month for Basic, $199.99 per month for Professional, and $399.99 per month for Executive. Yearly billing saves about two months ($990 per year for Basic, $1,990 per year for Professional). Postage is extra at USPS rates, and there are no contracts.

Greeting cards, small and large postcards, letters, and hundreds of gifts — including gourmet treats, drinkware, apparel, golf gear, journals, and custom-branded items. Everything is warehoused and printed on demand, so there are no minimum order quantities.
Who uses Mailbox Engine?
Real estate agents and other relationship-driven businesses use it for birthday and anniversary cards, closing and thank-you gifts, neighborhood farming postcards, review requests, referrals, and past-client reactivation.
How do I know if my mail worked?
On Professional and Executive plans, each mail piece can carry a dynamic QR code unique to the recipient. When someone scans it you get an instant alert naming who scanned, and the scan can trigger automated follow-up.
Do I need to set it up myself?
No. You can launch a ready-made campaign in minutes, or use the Done For You program and have the team set up your card and gift automations for you.
