Why ScanScope appears in this category
Niche scanning/inbound provider.
We classify it as a email security gateway from primary MX record (lowest preference) matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
ScanScope is a mailbox provider offering inbound email hosting for organisations across the web. Detected by its presence as a primary MX record, it serves a global audience but skews towards smaller organisations and United Kingdom-based sites.
For senders delivering to ScanScope-hosted domains and receivers managing those accounts, the provider's position outside the largest consolidated services means its infrastructure operates independently. Authentication standards — SPF, DKIM, DMARC — remain just as critical on ScanScope as on any provider, and senders should verify deliverability to ScanScope addresses during testing if email infrastructure reliability is a concern.

ScanScope in multi-provider email configurations
ScanScope often appears on domains that also route transactional email sends through Mandrill, creating a split between inbound provider (ScanScope) and outbound sender (Mandrill). This configuration requires SPF and DKIM records to explicitly permit Mandrill's sending infrastructure, and a DMARC policy that reflects both paths. Senders testing to such domains should verify that authentication records have been correctly configured, as misalignment between the two providers can lead to mail rejection or authentication failures.
