When managing email deliverability for digital agencies, one of the biggest challenges is ensuring that client domains are properly authenticated. SPF (Sender Policy Framework) records play a central role in this, but configuring, monitoring, and maintaining them across multiple clients can be overwhelming.
That’s where SPF management tools come in. In this in-depth comparison of DynamicSPF by Dmarcduty, UniversalSPF by Fraudmarc, and AutoSPF, we’ll explore each tool’s strengths, weaknesses, and ideal use cases.
By the end, you’ll know which solution is the best fit for your agency—whether you’re managing a handful of SMBs or dozens of enterprise clients.
Why SPF Record Management Is Critical
Before diving into the comparison, let’s cover the “why.”
SPF (Sender Policy Framework) is a DNS-based email authentication method that prevents spammers from sending unauthorized emails using your client’s domain. Without a properly configured SPF record:
- Spoofing attacks succeed more easily (clients’ domains can be impersonated).
- Emails get marked as spam due to failed authentication.
- Business reputations suffer, as recipients lose trust in branded emails.
For digital agencies, the complexity multiplies because:
- Each client may use multiple providers (Google Workspace, Microsoft 365, Mailchimp, HubSpot, Salesforce, etc.).
- SPF records have strict technical limits (no more than 10 DNS lookups).
- DNS misconfigurations can break email delivery.
- Frequent vendor changes (new sending IPs, third-party platforms) require constant updates.
👉 This is why agencies need automated SPF management tools—manual SPF record management simply doesn’t scale.
The Challenge of “Too Many DNS Lookups”
One of the most common problems agencies face is hitting the 10 DNS lookup limit in SPF.
Here’s what happens:
- Every include: in an SPF record requires a DNS lookup.
- If a client uses multiple SaaS email platforms, lookups add up quickly.
- Once you exceed 10 lookups, the SPF record fails silently, causing emails to be rejected or flagged as spam.
Flattening solves this by replacing include: mechanisms with resolved IP addresses. However, flattened records must be updated regularly (since IP ranges change).
This is where DynamicSPF, UniversalSPF, and AutoSPF come in—automating flattening, monitoring, and management.

- Strong monitoring and reporting
- Good for enterprises managing their own single domain
Cons
- Requires manual setup per domain
- Not scalable for agencies with many clients
- Steep learning curve for non-technical users
📌 Best For: In-house IT teams managing a small number of domains who want control over every detail.
UniversalSPF (Fraudmarc): Balanced But Limited
UniversalSPF by Fraudmarc offers a middle-ground solution. It automates some SPF management tasks but doesn’t go far enough for agencies managing multiple client environments.
Key Features
- Flattening & Lookup Reduction: Semi-automated process that lowers DNS lookup counts.
- SPF Health Monitoring: Alerts when records are misconfigured.
- Simplified UI: Easier than DynamicSPF, less technical complexity.
Pros
- Faster setup than DynamicSPF
- Better suited for SMBs or single organizations

Pros
- Scales seamlessly with multiple clients
- Removes the manual burden of DNS record editing
- Agency-friendly pricing model (no per-domain explosion)
- Built with agencies—not just IT teams—in mind
Cons
- May be more advanced than necessary for single-domain small businesses
📌 Best For: Digital agencies managing 10+ client domains who need an efficient, automated, and scalable solution.
