Key facts

Paloma is an email service provider primarily used by smaller and mid-market organisations, rather than the largest enterprise brands. It is most prevalent in the Swedish (.se) domain space, where it frequently appears in SPF configurations alongside Microsoft 365 in hybrid email environments.

For deliverability professionals and email infrastructure teams, Paloma's presence in the long tail of smaller sites means it is less often a priority concern in broad reputation monitoring compared to major ESPs; however, its concentration in Swedish-market mail flows means administrators will commonly encounter it in hybrid configurations, and understanding its role in a customer's mail stack is necessary when diagnosing delivery issues in that region.

SPF management in Microsoft 365 and Paloma combinations

When organisations deploy Paloma alongside Microsoft 365—a configuration common in Swedish markets—both services typically require SPF include mechanisms in the domain's DNS records. Administrators maintaining such hybrid setups should verify SPF authentication for both providers independently and ensure the combined record structure does not introduce validation issues.
