Key facts

Dixa is a software-as-a-service platform for email delivery. Customer domains delegate outbound mail to Dixa and publish SPF include mechanisms to authorise Dixa's mail servers to send email on their behalf.

Dixa's customers are predominantly smaller to mid-market organisations rather than the largest global brands, distributed across many countries and top-level domains with particular density in .com. It is frequently observed alongside Google Workspace. From a deliverability perspective, this distribution means that senders and receivers will encounter Dixa's shared email infrastructure in authentication records—a signal that mail is flowing through a managed delivery service rather than directly from the organisation's own mail servers.

SPF Configuration and Deliverability via Shared Infrastructure

When a domain publishes a Dixa SPF include, it authorises Dixa's mail servers to send email on its behalf. This delegation model means individual sender reputation is bound to Dixa's shared IP reputation rather than the domain's own infrastructure. Organisations using Dixa must monitor Dixa's IP reputation alongside their own domain reputation, as poor sending practices elsewhere in Dixa's customer base can affect deliverability for unrelated domains sharing the same infrastructure. Conversely, Dixa's managed reputation model can benefit smaller senders by leveraging established IP credentials, provided the platform enforces reasonable sending standards across its customer base.
