Delti is the email hosting service operated by InterNetX, a German domain registrar and web hosting provider, serving small and medium-sized organisations chiefly in German-speaking markets.
Delti's presence in email infrastructure is distributed across a specific demographic: the primary MX provider for smaller websites, with notable concentration in the .de top-level domain and related German TLDs. Senders experience Delti most directly when targeting recipients in Germany or organisations with German-registered domains. A common pattern is the co-occurrence of Delti mailboxes with Mandrill on the same domains, reflecting organisations that host inbound mail via Delti whilst using Mandrill (MailChimp's transactional service) for outbound campaign dispatch.

Delti's infrastructure clusters heavily in German-speaking regions and smaller-site deployments. This concentration is neither a deliverability problem nor an advantage—it is simply the shape of its market. For senders and deliverability teams targeting German audiences or auditing inboxes on German domains, Delti is a frequent and relevant part of the landscape. Campaigns focused on other regions will encounter it less frequently. Testing scope and prioritisation should align with your own recipient geography and market focus.
