Locaweb is a Brazilian web hosting and email services provider that operates email infrastructure across the .com.br domain space and serves regional Brazilian businesses. The company provides shared and managed email hosting to smaller and mid-sized enterprises rather than serving as a destination for global brand communications.
When a recipient domain's MX records point to Locaweb, it indicates a regionally focused business in the Brazilian market. This concentration makes understanding Locaweb's authentication requirements, filtering policies, and reputation handling directly relevant to anyone maintaining sender reputation in Brazil or managing campaigns targeting Brazilian recipients — and less critical for global-audience senders with minimal Brazilian engagement.

Locaweb hosts email for many smaller domains on shared infrastructure, which means SPF, DKIM, and DMARC adoption varies significantly across the provider's user base. Senders should not assume that all Locaweb-hosted recipients enforce DMARC policy, and must ensure their own SPF records are properly scoped to avoid triggering filtering on shared-hosting providers. Reputation systems may handle mail from shared-hosting providers with closer scrutiny than consolidated enterprise infrastructure, making robust authentication practices and clean sending practices especially important for maintaining deliverability to Locaweb-hosted mailboxes.
