- If omnichannel employee communications are a first-class requirement
- If coordinated publishing across email, intranet, mobile, and Teams/Viva Engage with unified analytics is required, platforms that provide omnichannel support may be more appropriate.
- If Outlook add-in performance and reliability are critical risks
- Add-ins can affect client performance; if the organization experiences significant Outlook slowness, introducing additional add-ins may worsen user experience or increase IT support needs.
- If security review cycles are extremely long and rapid time-to-value is required
- Anecdotal reports indicate some organizations experienced lengthy security reviews; large enterprises should plan for security review timelines.
- If transparent public security artifacts are required
- The vendor indicates certain compliance artifacts are available under NDA rather than publicly downloadable; organizations that require publicly posted trust center artifacts may consider alternatives.
- Outlook add-in disablement / "PoliteMail disappeared" scenarios
- The vendor knowledge base documents scenarios where add-ins can be disabled and menus or toolbars may disappear, and references standard Outlook add-in behaviors.
- Client transition complexity (Classic Outlook vs New Outlook)
- The vendor supports both classic and modern add-in models and offers online/unified app variants. Supporting multiple client types can increase governance and support complexity.
- Potential performance constraints at scale
- Release notes and knowledge-base guidance reference recommendations to use a server-based sending mode for very large lists to improve send performance and avoid hanging sends.
- Roadmap ambiguity
- Public roadmap dates and detailed commitments were not located in this research set; buyers should request written roadmap commitments for critical features such as new Outlook parity, admin controls, audit logging, and segmentation enhancements.
