marketing saas business

EMARSYS-AS is operated by Emarsys eMarketing Systems GmbH.

What it's used for

  • The address space carries corporate infrastructure for a customer engagement platform, evidenced by the netname AT-EMARSYS-20070730 and reverse DNS entry e3pmta126.emarsys.net.
  • The AS announces 512 IPv4 addresses within a single prefix (91.194.248.0/23) and maintains 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access network.
  • Traffic from this AS consists of backend services and API endpoints supporting Emarsys's marketing automation and customer data platform operations.

Notable

  • Registrant data aligns with the announcer, listing Emarsys EU NOC and EMARSYS eMarketing Systems GmbH.
  • Emarsys was acquired by SAP in 2020 and subsequently rebranded as SAP Engagement Cloud.
  • The inventory consists of a single contiguous /23 block, reflecting a compact internal network design.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 447 networks and 1,845 prefixes, as published 2026-10-31. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
