Fidelizador is a regional email service provider serving organisations across Latin America, particularly in Chile. It appears in email infrastructure via SPF authentication mechanisms, where organisations delegate send authority to it for transactional and marketing email.
Fidelizador's footprint spans smaller to mid-sized organisations rather than major brands, concentrated in the .cl domain. It frequently appears alongside Microsoft 365 in hybrid deployments. For anyone handling mail involving Fidelizador—whether assessing SPF records, evaluating delivery paths, or auditing mail sources—its presence typically signals a regional SMB using delegated sending authority for marketing or transactional campaigns.

Fidelizador's presence in email authentication is predominantly via SPF include mechanisms, where organisations authorise it to send on their behalf by adding an include in their SPF record. Because Fidelizador is concentrated in regional and SMB deployments, the organisations referencing it often have simpler SPF configurations than large enterprises—though the addition of Microsoft 365 SPF entries alongside Fidelizador creates a modest authentication chain that mail receivers evaluate. Mail receivers and administrators should inspect SPF records containing Fidelizador includes the same way they would any third-party sending service: verify the legitimacy of the delegation, monitor for excess includes that might breach SPF record length limits, and ensure the service is genuinely in use if the organisation's security posture requires regular audits of outbound mail paths.
