SPF authentication and Google Workspace coexistence
Because RD Station is commonly deployed alongside Google Workspace in the .com.br space, email operators should understand the resulting authentication landscape. When both services' SPF includes appear in a single record, configuration complexity increases; organisations that send to Brazilian recipients or manage infrastructure in this region should verify that their SPF records properly reference both services and that email routing between them works as intended.
