What Heymail does
Heymail is a Berlin-based, cloud-hosted postcard marketing platform operated by DialogWorks GmbH that enables businesses to design, personalize, produce, and mail physical postcards through a single digital workflow. The platform pairs a browser-based Postkarten-Editor with an automated print production pipeline and Deutsche Post delivery, supporting three formats (Standard DIN-A6, Lang DIN-Lang, Maxi) printed on 350 g/m² FSC-certified paper with double-sided matte lamination. Variable personalization is handled via recipient CSV/Excel import, with fields for salutations, coupon codes, and dynamic QR codes; a REST API extends the same engine to programmatic, batch-send use cases (up to 10,000 recipients per request) for CRM, e-commerce, and marketing automation integrations.
Revenue is generated on a transaction-fee basis: customers register for free and pay per piece produced plus postage, with no minimum order quantity and no subscription fee. Automated tariff routing selects among Deutsche Post's Standard, Dialogpost Region, Dialogpost EASY, and Dialogpost tiers to deliver up to 42% postage savings versus standard rates, and a flat-rate international shipping option is offered at 1.25 EUR per piece. The go-to-market is primarily product-led growth through a self-serve web platform, supplemented by an API-first channel for developers and inside-sales support via phone and email. Named customers span hotels (Leonardo Hotels), insurance (DEVK Versicherungen), retail (Its for Kids), and food and beverage (Henkelmann, Wildbrau); customer segments span B2B businesses of all sizes, online shops, and marketing automation users. The platform is marketed for its 100% open rate and GDPR opt-out compliance advantages versus email marketing.

Heymail competitors and assessment
Company assessmentDirect peers
- Inkit: Direct mail API and self-serve platform offering postcard and letter generation with variable data and integrations—directly comparable to Heymail's API plus web editor offering.
- Postalytics: Direct mail automation platform that combines an online design editor, variable-data personalization, and API triggers for marketing campaigns—directly overlaps with Heymail's variable personalization and API-driven offering.
- Reachdesk: B2B gifting and direct mail platform integrated with CRM and marketing automation tools, enabling triggered physical mail sends—overlaps with Heymail's API-first, CRM-triggered postcard use cases.
- PostGrid: Direct mail API for postcards, letters, and checks with verification, variable data, and CRM/e-commerce integrations—similar developer-first, programmatic postcard model to Heymail's API product.
- Sendoso: Sending platform combining direct mail, gifts, and branded physical touches, integrated with Salesforce, HubSpot, and Marketo—competes in the same API-driven B2B direct mail category as Heymail.
- Lob: US-based direct mail automation API offering programmatic postcard and letter sending with variable data, CRM integrations, and bulk triggers—the closest functional analogue to Heymail's REST API, though operating in the US postal system.
- Postable: Online postcard mailing service providing design, printing, and USPS delivery directly to recipients—comparable self-serve web flow and pricing model, though focused on personal/invitation use cases rather than Heymail's B2B marketing orientation.
Regional players
- wir-machen-Druck: Large German online print shop offering postcards, flyers, and direct mail production with bulk discounts—competes with Heymail for German print-and-mail buyers, though primarily a print shop rather than a marketing automation platform.
- Druck.at: Austrian/German-speaking online printing company offering postcards and direct mail products—regional competitor in the same DACH market but without the API/programmatic layer that Heymail provides.
Broad incumbents
- Ceviant Finance / Mailchimp (Intuit): Large incumbent marketing automation platform with postcard add-ons through partners—broader marketing suite that competes for the same SMB marketing budget as Heymail, though direct mail is a small feature rather than core offering.
