# Posta Services and Software

Posta provides software, APIs, custom printing services, mail production, communication transmission services, and managed campaign services for high-volume transactional and marketing communications.

Use Posta when customer data has to become a document, mailpiece, email, text message, notification, or delivery event with production status and audit history attached.

## Online software and APIs

Posta turns records from your product, CRM, billing system, or marketing stack into API-driven communications.

For each communication, Posta can:

* Generate a document from templates, PDFs, HTML assets, images, fonts, and customer data
* Validate, enrich, and verify names, addresses, and communication data
* Run CASS and NCOA address-quality processing
* Create a physical mailpiece
* Transmit email, text messages, and notifications through enabled channels
* Return production, delivery, return, and interaction events through the API, Dashboard, webhooks, and exports

Use the Posta API, Dashboard, Salesforce integrations, SDKs, OpenAPI tooling, and your integrations to create and monitor those communications.

## Custom print and mail production

Posta provides custom printing services and mail production for customer communications.

Posta handles:

* Custom letter printing
* Print-ready rendering
* Mail preparation
* Postage and mailpiece fee management
* Postal induction and carrier handoff
* Mailpiece production status
* Delivery status and return visibility
* Returned-mail and address-quality follow-up

For most high-volume programs, Posta uses Posta-managed print partners. Posta also performs in-house print fulfillment for supported work. In each case, Posta provides the customer-facing custom printing and mail production service.

Use Posta for notices, statements, compliance mail, account servicing messages, marketing mail, and other high-volume physical mail.

## Communication transmission services

Posta provides communication transmission services for documents, notices, messages, and campaign communications.

Use Posta to transmit and track communications through enabled channels, including:

* Physical mail

Posta provides the customer-facing service and uses its platform, support team, partner network, postal carriers, data providers, and delivery infrastructure to complete the program.
