Why Liana Technologies appears in this category
Liana Technologies — Finnish marketing automation suite.
We classify it as a email service provider from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Liana Technologies is a Finnish email service provider serving smaller and mid-market organisations, primarily across Nordic markets. The company operates email infrastructure that handles outbound messaging for a range of business segments, from newsletters to transactional mail.
Its footprint across the web sits predominantly in the long tail of smaller websites rather than Fortune 500 companies, with notable concentration in the .fi domain space. Liana Technologies is often deployed alongside Microsoft 365, suggesting it serves organisations in Northern Europe that combine Microsoft's productivity stack with specialist email sending infrastructure. For senders using Liana, the main implication is careful SPF and DNS configuration; for receivers, its presence typically signals legitimate mail from smaller Nordic organisations rather than global-scale deployments.

SPF configuration and the Liana Technologies include
When Liana Technologies sends email on behalf of a customer organisation, the customer's SPF record must include Liana's sending infrastructure via an SPF include mechanism. This allows mailbox providers to verify that mail signed with the customer's domain is legitimately sourced from Liana's servers. Organisations using Liana should audit their SPF records to ensure the correct include is present and that they have not exceeded the DNS lookup limit (the practical maximum is ten mandatory queries). Since Liana-powered senders often also use Microsoft 365, the SPF record may combine both Microsoft's include:spf.protection.outlook.com and Liana's mechanisms, requiring careful ordering to remain within lookup limits.
