What Print.one is

Print.one provides a direct mail API for sending personalized postcards, greeting cards, and letters from business software. It is intended for marketing, sales, and HR communications, such as customer reactivation, welcome messages, and employee birthday cards. Users can create designs in an editor or start with pre-designed templates, then add variable text, images, and recipient-specific QR codes. Address lists can be uploaded by CSV, automated, and deduplicated; address verification is also supported. Listed integrations include Zapier, HubSpot, Shopify, Salesforce, Power Automate, Klaviyo, and Make.com, among others. The service also offers CSV and email connections, and says systems that support API calls or webhooks can generally connect. Formats include A5 and A6 postcards, square greeting cards, and A4 letters, with worldwide delivery. Individual sending is available from one piece; an economy batch option starts at 300 pieces, is limited to the Netherlands, and is delivered the following week. Pricing starts from €0.69, while per-piece costs vary by product, destination, finish, and quantity. Print.one says mailing data is stored within the EU and automatically deleted after 90 days.
