Key facts

ActiveTrail is an email service provider and marketing automation platform operated by an Israeli company, primarily serving small to medium-sized businesses and publishers across multiple geographies.

In email infrastructure, ActiveTrail's footprint is concentrated in the long tail of smaller organisations rather than the largest global brands, with a pronounced presence across Israeli domains. Because it is commonly deployed alongside Microsoft 365, organisations running both platforms create hybrid authentication and routing scenarios that deliverability professionals should understand when troubleshooting mail flows or testing inbox placement across diverse sender profiles.

SPF and authentication in mixed Microsoft 365–ActiveTrail deployments

ActiveTrail requires senders to publish specific SPF include mechanisms in their DNS records; when an organisation uses both ActiveTrail and Microsoft 365, the SPF policy must accommodate includes from both platforms, increasing DNS record complexity and raising the risk of SPF exhaustion on large sender domains. This co-deployment pattern is commonplace in Israel-based and European SMBs and warrants careful SPF syntax review during any authentication audit.
