Introduction: Why MSPs Are Moving Beyond PowerSPF
Email remains the most popular attack vector in 2025, with over 90% of cyberattacks beginning in the inbox. For Managed Service Providers (MSPs), safeguarding client domains against spoofing, phishing, and impersonation is no longer optional — it’s mission-critical.
Sender Policy Framework (SPF) is one of the oldest and most important defenses against email impersonation. By restricting which servers are allowed to send on behalf of a domain, SPF helps prevent spoofing and improves deliverability. However, SPF records come with a fatal limitation: the 10 DNS-lookup maximum. Once exceeded, SPF records begin to fail, causing legitimate emails to bounce or land in spam folders.
PowerSPF by PowerDMARC was created to solve this challenge using “flattening,” which rewrites SPF records into a static list of IPs. Unfortunately, static flattening quickly breaks as email providers change IPs, leaving MSPs with recurring deliverability issues across multiple clients. For MSPs managing dozens or hundreds of domains, this creates a cascade of support tickets and frustrated customers.
That’s why MSPs in 2025 are increasingly searching for PowerSPF alternatives that:
- Update dynamically (not statically)
- Scale across multi-tenant environments
- Integrate with existing MSP toolsets
- Offer transparent pricing for resellers
- Provide compliance-ready reporting
In this guide, we’ll explore the 12 best alternatives to PowerSPF for MSPs in 2025. Each section includes vendor overviews, feature comparisons, MSP use cases, pros and cons, pricing insights, and support options — helping you find the right solution for your clients.

FAQs
Q: What is SPF flattening?
A method of rewriting SPF records into static IPs. PowerSPF uses this, but it’s unreliable as IPs change.
Q: Why not just use PowerSPF?
Static flattening breaks easily, causing deliverability issues.
Q: Can I manage SPF manually?
Yes, but it doesn’t scale for MSPs managing multiple clients.
Q: Do I need DMARC if I have SPF?
Yes — SPF alone isn’t enough to prevent spoofing.
Conclusion
For MSPs in 2025, SPF management is a strategic priority. Deliverability failures don’t just cause technical issues — they erode client trust.
