Are your agency’s client emails landing in spam because of broken or bloated SPF records? Choosing the right SPF management solution can make the difference between flawless deliverability and constant email headaches.
In this guide, we’ll compare PowerSPF by Powerdmarc, DynamicSPF by Dmarcduty, and AutoSPF head-to-head. You’ll see how each tool performs across features, automation, pricing, user experience, and integrations—and we’ll reveal which one is the best fit for digital agencies managing multiple client domains.
Why SPF Management Matters for Agencies
Sender Policy Framework (SPF) is one of the core DNS records that determines whether an email is authenticated or rejected by receiving servers. But SPF records can quickly become too long, outdated, or misconfigured, especially when:
- Clients use multiple third-party senders (Google Workspace, Microsoft 365, Mailchimp, Salesforce, HubSpot, etc.)
- Records exceed the 10 DNS lookup limit, triggering “too many DNS lookups” errors
- Manual edits lead to broken syntax or missing IP ranges
- Agencies forget to update SPF when a client adds a new tool
For agencies, the stakes are high: poor SPF management = clients blaming you for deliverability failures, lower campaign ROI, and potential phishing risks.
That’s where SPF automation and flattening tools step in—making SPF management scalable, reliable, and hands-free.

FAQs: SPF Flattening & Email Deliverability for Agencies
1. What is SPF flattening, and why do agencies need it?
SPF flattening reduces the number of DNS lookups in an SPF record by consolidating “include” statements. Agencies need it because client domains often exceed the 10-lookup limit due to multiple third-party senders. Without flattening, SPF breaks and emails fail authentication.
2. How does AutoSPF differ from PowerSPF and DynamicSPF?
AutoSPF is automated and built for agencies managing multiple domains, while PowerSPF is geared toward enterprise IT/security and DynamicSPF is a lightweight single-domain tool.
3. What happens if an SPF record exceeds the 10-DNS-lookup limit?
Emails will fail SPF authentication, often leading to deliverability issues or rejections. AutoSPF prevents this automatically by keeping records optimized.
4. Can I manage multiple client domains with AutoSPF?
Yes. AutoSPF is designed for agencies, offering bulk management, white-label reports, and real-time monitoring across unlimited client domains.
5. Is PowerSPF better for compliance than AutoSPF?
PowerSPF is bundled with compliance-focused tools and is strong in regulated industries. However, AutoSPF provides easier, more scalable SPF management for agencies handling diverse clients.
6. Can DynamicSPF handle complex client setups?
No. DynamicSPF is best for simple, single-domain SPF flattening. It lacks automation, reporting, and integrations needed by agencies.
7. How much time can agencies save using AutoSPF?
Agencies can save dozens of hours per month by avoiding manual DNS edits, troubleshooting SPF errors, and chasing deliverability complaints.
8. Does fixing SPF guarantee emails won’t go to spam?
No tool can guarantee inbox placement, but proper SPF management is a critical step in passing authentication checks, improving sender reputation, and boosting deliverability.
