PostGrid
A platform for automating print and mail communications.
PostGrid is a platform and REST API for automating offline communications, covering transactional and marketing direct mail alongside address data quality. It addresses the manual work of printing, mailing and checking addresses by letting teams send personalized letters, postcards and checks through API calls or integrations, while verifying, completing and standardizing addresses to postal standards.
Core capabilities include a Print & Mail API, an Address Verification API with autocomplete, bulk verification and an AI-driven multilingual freeform address parser, plus real-time tracking and reporting. Integrations cover Salesforce, HubSpot, ActiveCampaign, Zapier, Shopify, Zoho and others, with connections to more than 1,600 apps through Zapier. The service supports US and Canadian checks, addresses across 245+ countries, and a two-business-day processing SLA.
PostGrid is aimed at marketing, developer, billing, compliance and customer success teams, as well as CRM and software workflows. It is offered through an API with test keys and detailed documentation, a web platform, and integrations; compliance features reference HIPAA, PIPEDA, GDPR and SOC-2 handling.
