Direct mail automation and API: send a postcard like you send an email

What can you automate with direct mail?

The same journeys you already automate by email, with the response rate of a physical piece. Welcome cards to new customers. Win-back offers to customers who have not bought in 90 days. Abandoned-cart postcards with the product pictured. Renewal and re-enrollment letters. Appointment recall cards for dentists, vets and salons. Birthday and anniversary offers. Review requests after a completed job. Follow-ups to leads who filled a form and then went quiet. Each one is a template plus a trigger.

• E-commerce: abandoned cart, first purchase thank-you, win-back, VIP
• Home services: post-job review request, seasonal maintenance reminder
• Healthcare: recall, missed appointment, new patient welcome
• Insurance and finance: renewal, rate change, cross-sell, birthday
• Real estate: new lead follow-up, anniversary of purchase, neighbor "just sold"
• SaaS and B2B: trial-to-paid nudge, churn risk, account expansion

How the API works

Create a template with merge fields and a design, or upload a PDF per send. Call the send endpoint with the recipient address and the merge data; the API validates the address, returns an ID and a rendered proof URL, and queues the piece. It prints in the next business day's batch and mails First-Class by default. Webhooks report rendered, printed, mailed, in transit and delivered, using USPS scan data. Everything the API does is also available in the dashboard, so a marketer can send a test without a developer.

Why one-off pieces cost the same as a batch

Because we batch them. Every triggered piece from every customer prints in the same daily run, on the same presses, and presorts with everything else going to that ZIP. The unit cost is the run's cost, not yours alone, so a single 6×11 costs what a 6×11 costs at the rate quoted for your program, and the postage is the presorted First-Class rate. There is no per-send API fee.

Direct mail vs. email automation

Email is free and ignored; a postcard costs real money and is read. The right use of automated mail is not to replace email but to add a physical touch at the points where email is failing: the customer who unsubscribed, the lead who has not opened anything in a month, the high-value account where a postcard is trivial against the revenue. Most customers run mail as a step inside an existing email journey, triggered when the email steps are exhausted.
