A mailing list can be created using the create endpoint and then recipients can be added as JSON data using the endpoints recipients/create or recipients/create-multiple.
thanks.io can generate a mailing list using a radius search to target recipients within a specific geographic area.To run a search, simply provide a search address, recipient type, and desired recipient count. The system uses the address as the center point and identifies the nearest recipients within a maximum radius of 5 miles.Each record added to the mailing list is billed at $0.05.
