Informz is an email service provider (ESP) operated by Higher Logic. It delivers transactional and marketing email, serving primarily non-profit organisations and membership communities.
Informz occupies a specific niche in email infrastructure: it appears predominantly in the long tail of smaller organisations rather than major global brands, and its adoption concentrates heavily in the .org namespace. It is frequently deployed alongside Microsoft 365 in organisational email stacks. For email operators and deliverability professionals, this footprint pattern means Informz traffic typically signals association or membership-focused senders, which directly informs how their authentication and reputation are assessed.

Organisations using Informz commonly run it alongside other email systems—most often Microsoft 365. This creates composite SPF records that include both Informz and Microsoft mechanisms, complicating SPF alignment and DMARC policy enforcement. Because Informz appears mainly in smaller organisational contexts, misconfigurations in these mixed stacks—duplicate includes, absent DMARC policy, or overly permissive SPF strings—are more frequent than in centralised single-ESP deployments. Receivers evaluating sender authentication must account for this structural pattern when assessing mail from Informz-enabled senders.
