Introducing MailerBot

MailerBot is a programmatic direct mail platform built by the team at Handwrytten, the world leader in handwritten note mailings. Whether you're sending postcards or letters, MailerBot handles the entire process: design, print, stamp, mail, and track. It's the fastest, most affordable way to run automated direct mail campaigns that actually get opened, read, and acted on.

Built for businesses that demand both scale and quality, MailerBot combines a full print shop backing with an intuitive web dashboard and a powerful REST API. The result is a platform where you can create highly personalized campaigns, launch them with a single click, and monitor responses in real time - all without monthly fees or minimum commitments.

Why You'll Love It

• Lightning-fast turnaround – Backed by Handwrytten's full production facility, your campaigns move from design to mailbox faster than any competitor. On demand production means your pieces are printed and shipped the moment you hit send.
• Unbeatable pricing – Postcards start at just $0.49 per piece and letters at $0.89, with no monthly fees and no minimums. That means better profit margins on every campaign you run.
• Intuitive postcard customizer – The best postcard customizer on the market. A drag-and-drop visual canvas editor lets you add text, images, shapes, gradients, and QR codes to create unique designs without any design expertise. It's super easy to use.
• Full print shop backing – This isn't a middleman platform. MailerBot is powered by Handwrytten's in-house print infrastructure, ensuring good quality and consistent print quality on every single piece.
• API-first design – With over 50 endpoints across more than a dozen resource categories, MailerBot's REST API lets developers programmatically manage contacts, templates, mailings, pricing, and webhooks. Seamless store integrations with your existing tech stack.

What Makes It Different

Most direct mail services focus on basic batch-and-blast automation. They require manual uploads, offer limited personalization, and lock you into contracts with slow turnaround times. Many print providers in the space are simply brokers - they don't own the production.

MailerBot is built differently:

• Handwrytten's proven print infrastructure – The biggest difference is what's behind the platform. Handwrytten's full print shop give MailerBot production capacity that demand companies simply can't match. This isn't outsourced fulfillment - it's a company that physically picks up pens and writes with real ink, delivering authenticity at scale. MailerBot automates physical direct mail through a web dashboard or API, giving you complete control over the process.
• Advanced postcard customization – Most competitors offer basic templates or PDF uploads. MailerBot gives you a full visual canvas editor with all the features: full-color front and back design, image assets, merge tags for dynamic personalization, embedded QR code tracking, and custom signature options. MailerBot allows users to design postcards through a visual canvas editor that rivals professional design tools.
• Programmatic precision – Real-time cost estimation endpoints let you preview per-zone recipient counts and per-piece pricing before you spend a dollar. MailerBot tracks analytics on delivery rates and customer engagement, so you can optimize every campaign. Smart dynamic personalization automatically fills individual pieces with recipient data - names, companies, custom fields - making each mailer feel handcrafted.

How It Works

1. Design & Configure Select a template or upload your own print-ready PDF. Use the visual postcard customizer to create full-color designs, or the rich text editor for letters. Add merge tags to personalize each piece for your target audience. MailerBot can validate postal addresses for accuracy when you import your contact list, reducing undeliverable mail. MailerBot supports both personalized mail merges and visual content creation on one platform.
2. Target & Launch Import contacts via CSV, organize them into segmented lists, and let the platform flag duplicates and invalid addresses. MailerBot facilitates importing contact lists and managing segmented campaigns with precision. Schedule mailings for specific dates or set up event-based triggers - direct mail can be triggered based on web events or user actions like cart abandonment, trial expiration, or subscription renewals. Automated recurring campaigns allow scheduling without manual intervention. Then launch from the dashboard or via the API.
3. Track & Optimize MailerBot provides campaign tracking for monitoring delivery status, QR code scans, spend breakdowns, and response metrics. Filter by date, export reports, and drill down to per-recipient performance. MailerBot's API allows for programmatic integration into marketing workflows, so your data flows directly into your CRM. Use postage zone tools to manage costs and optimize future sends for long term success.
