https://PostalAgent.com – Send personalized postcards online.

Upload a CSV or circle neighborhoods on Google Maps to build your address list (consumers or businesses). Printing and postage included in one price.

In the last 30 days I've added an API plus integrations for Pipedrive, Zoho, and Follow Up Boss. If anyone wants to help test these new integrations, I'll set you up on a special plan and let you send mail at my cost (roughly the price of a stamp).
