According to Live Direct Marketing's daily Tranco top-1M scan (July 12, 2026), Autotask (ConnectWise) is the SaaS sender for 482 domains — 0.08% of 617,244 SPF-publishing domains. Detection method: include: mechanisms in the SPF record.
Autotask is a Professional Services Automation platform owned and operated by ConnectWise. The service is designed for managed service providers (MSPs), IT service organisations, and consulting firms, providing tools for client engagement management, ticketing, billing, and service delivery automation.
Autotask appears in email infrastructure SPF records across a long tail of smaller and mid-market organisations rather than the largest global brands, with notably higher concentration in the .com domain space. Its frequent deployment alongside Microsoft 365 reflects a common pattern: organisations maintain Office 365 for employee mail whilst using Autotask to automate client-facing communications and service notifications.

Autotask sends email on behalf of client domains using its own infrastructure, documented in those domains' SPF records. Because many organisations transmit mail through shared IP pools, sender reputation and filtering decisions at recipient systems accumulate across the entire tenant population rather than remaining isolated per-customer. A high-volume client's delivery reputation thus affects the IP space available to all other Autotask users, particularly where recipient systems like Microsoft 365 apply IP-based filtering and rate-limiting.

An Autotask SPF include is required for the platform to send authenticated email from your domain, including service notifications and client alerts. Removing it would cause Autotask-originated messages to fail SPF validation and face rejection or filtering by recipient mail systems.
