Publisher claims: "Unofficial Go client for the PostGrid print and mail and address verification APIs. Package postgrid (github.com/psyb0t/go-postgrid), generated with oapi-codegen, has typed methods for contacts, templates, letters, postcards, cheques, self mailers, campaigns, mailing lists, reports, webhooks and address verification, authenticated with an API key in the X-API-Key header. Use when Go code needs to send physical mail, manage PostGrid print and mail resources or verify addresses, or already imports go-postgrid."
