What is postal mailing?

Postal mailing is a direct marketing strategy that uses physical mail to connect with customers in a personalized way.

Unlike email, it has open rates above 90% and stays in the home for up to 7 days.

Thanks to Posthero you can automate the whole process: from segmentation to shipment.

Automated physical mail for any use case

Send physical mail like a digital campaign.

Upload your data from your CRM or ecommerce

Integrate Posthero with the tools you already use to communicate with your customers. Connect your CRM or ecommerce platform — Shopify, Klaviyo, HubSpot or any in-house system via API — and automatically sync your contacts and segments.

In seconds you'll have your databases ready to launch personalized postal campaigns, whether to active customers, dormant leads or users with specific behaviors. All information stays secure and up to date, ready to transform digital data into effective physical communications.

Use our templates or upload your design

Design your letter, postcard or flyer directly in the platform. Choose between templates optimized for postal mailing or import your own design in a few clicks.

Each template is built to maximize readability and visual impact while keeping your brand consistent. Customize text, images, colors and calls to action so every shipment carries the exact tone and identity of your business.

Prefer full control? Upload your professional print-ready design and Posthero handles the rest.

Automate shipments with triggers, dates or specific segments

Create automated flows that send your campaigns at exactly the right moment. Schedule shipments by key dates (birthdays, contract renewals, events) or define custom triggers: customers inactive for 30 days, first purchase, abandoned cart and more.

You can combine conditions too — for example "premium customers without a purchase in the last 60 days". With Posthero, physical mail stops being a manual action and becomes an automated sequence as measurable as any digital campaign.

Measure results with QR codes and dashboard tracking

Track every shipment with precision. Every letter or postcard includes a unique QR code or personalized link that lets you track opens, site visits and conversions.

From your dashboard you can monitor postal campaign performance: response rate, estimated ROI and comparisons by segment or design. You'll know exactly which messages work best and can optimize the next campaigns, combining digital traceability with the tangible impact of physical mail.

FAQs

What's the difference between postal mailing and door-to-door (buzoneo)?

Postal mailing is a personalized action that sends letters or postcards to specific contacts — by name, address and specific data — usually integrated with a CRM or customer database. Door-to-door, on the other hand, distributes materials without personalization or segmentation: the same flyer is delivered to every home in an area. In short, postal mailing reaches people; door-to-door reaches mailboxes.

Can I personalize every letter?

Yes. With Posthero you can fully personalize each shipment, just like a digital campaign. You can include the customer's name, references to previous purchases, unique discounts or different messages per segment. All that data is pulled automatically from your connected CRM or ecommerce, so you don't have to do it manually.

What data do I need to get started?

You just need a database with valid postal addresses and at least one of the following fields:

Recipient name or business name
Full address with postal code
(Optional) Purchase or behavior data if you want to segment or personalize

Posthero helps you clean and validate the data before each shipment to avoid errors and returns.

Can I measure the conversions from shipments?

Yes. Every letter or postcard includes a unique QR code or personalized URL that lets you track visits, scans and conversions. From the Posthero dashboard you can see metrics like:

Response rate
Estimated ROI
Conversion by design or segment

You'll know which campaigns generate the most impact and can optimize your next shipments just like a digital campaign.
