Why Everbridge appears in this category
Everbridge — critical event management.
We classify it as a SaaS sender from include: mechanisms in the SPF record matching a maintained provider rule. This is infrastructure attribution from public DNS, not evidence of a direct contract or exclusive use.
Everbridge is a SaaS platform that handles email dispatch and communications relay on behalf of client organisations. It authorises client domains via SPF records, allowing Everbridge's infrastructure to send messages that authenticate under those domain names, particularly for high-volume operational and crisis notifications.
In practice, Everbridge appears as an SPF include mechanism in smaller to mid-market domains—concentrated in .com space and often coexisting with Microsoft 365 in the same domain's email infrastructure. For senders using Everbridge, domain deliverability depends partly on Everbridge's collective sender reputation across its user base; for receivers and security teams, its presence in SPF records signals that email may originate from shared infrastructure, which is relevant context when evaluating sender authenticity.

Shared Sender Reputation and Third-Party Relay Risk
When Everbridge authorises a domain via SPF, that domain's email reputation becomes intertwined with Everbridge's collective IP space reputation. Any list-quality issues, complaint patterns, or misuse by other Everbridge customers can impact delivery of your own mail, even if your sending practices are sound. This is the fundamental trade-off of third-party email relay platforms: operational convenience and scalability versus independence from other senders' behaviour and reputation decisions by mailbox providers.

Frequently asked questions
