Understanding the Sources Table
The sources table is the central working area of SPF Management. It lists every email source detected in your DMARC reports, with all the data you need to make an approve/reject decision.
Column Reference
| Column | What It Shows |
|---|---|
| Source / Service | The sending IP address or, where recognised, the email service name (e.g. "Mailchimp", "SendGrid"). Recognised services are shown with their logo. |
| Volume | Total emails sent from this source in the reporting period. Higher volume sources have greater impact on your compliance rate — prioritise these. |
| SPF Pass Rate | Percentage of this source's emails that passed SPF. If the source is not in your SPF record, this will be 0%. |
| DKIM Pass Rate | Percentage of emails with a valid DKIM signature. High DKIM rates are a strong legitimacy signal even when SPF fails. |
| DMARC Pass Rate | Combined pass rate — emails that pass either SPF or DKIM (with alignment). This is the number that directly affects your DMARC compliance score. |
| Confidence | AI trust score (0–100%). Combines authentication rates, service recognition, sending history, and volume patterns into a single approval recommendation score. |
| First Seen / Last Seen | How long this source has been sending. Established senders (30+ days) score higher than brand-new sources. |
| Include in SPF | The checkbox that controls whether this source is in your managed SPF record. This is the single authoritative control — checking it adds the source, unchecking removes it. The SPF record updates automatically. |
| Status | Current state: Pending, Approved, Monitoring, Rejected |
AI Recommendation Icons
| Icon | Recommendation | Suggested Action |
|---|---|---|
| ✔ | Add to SPF | Safe to approve — strong signals of legitimacy |
| 👁 | Monitor | Watch for 7 days before deciding |
| ❌ | Reject | Suspicious or unverifiable — reject this source |
The Hidden Sources Tab
Sources that have been rejected, dismissed, or automatically removed don't disappear permanently — they move to the Hidden tab. From there you can:
- Review what was removed and why
- Restore a source if it was removed incorrectly
- See sources flagged as redundant (their service's
include:directive already covers them)
Filtering and Sorting
Use the table controls to focus on what matters most:
- Sort by Volume — approve the highest-impact sources first
- Sort by Confidence — work from most to least certain
- Filter by Status — view only pending, monitoring, or approved sources
- Search — find a specific service or IP address
The Include in SPF Checkbox is the Single Source of Truth
Only sources with Include in SPF checked are added to your managed SPF record. Status badges are informational — they do not control what's in your SPF record. The checkbox does.
