Summary

Mailjet

France · AI-generated

email saas infrastructure

The AS handle MAILJET is held by Mailjet SAS.

What it's used for

  • The address space carries transactional and marketing email infrastructure, evidenced by reverse DNS records such as send.eu.mailgun.net and mailjet.com.
  • The AS announces 11,776 IPv4 addresses across 15 prefixes with only 1 observed neighbour, indicating a dedicated service network rather than a transit provider.
  • Traffic consists of outbound email delivery and API endpoints for the Mailjet platform, a French SaaS provider for marketing and transactional email.

Notable

  • Registrants include both Mailjet entities (e.g., MAILJET SAS, MAILJET OPS) and Mailgun Technologies Inc., reflecting the integration of Mailgun's infrastructure into the Mailjet AS.
  • Mailjet SAS is a subsidiary of the Swedish publicly listed company Sinch AB.
  • The inventory is a mix of Mailjet-specific blocks and former Mailgun blocks, with netnames like MT-757 and FR-MAILJET-SAS-20120910.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
