Reasoning
All sources indicate that Email Integration (Inbox Sync) is supported. Each URL provides a single opinion (despite multiple affirmative entries in some sources), so we aggregate at the URL level and consider the strongest evidence. The most credible sources (Break Cold with 1.00, Capterra 0.95, OnePageCRM reviews 0.95, Forbes 0.90) all agree, and there is no conflicting source suggesting false. This converging high-confidence evidence supports true.
