How to monitor sending domains
Keep sending domain infrastructure healthy — authentication, reputation, and DNS — continuously.
The situation
Sending domains are more vulnerable than parked domains — they are actively used, more likely to be listed on blacklists, and more likely to be targeted by spoofing attempts.
Before you begin
The operational path
The goal isn't just to find the error. The goal is to move from detection to a verified infrastructure state.
What could have caused this?
Cause
What changed
Possible impact
Authentication gap
SPF, DKIM, or DMARC misconfigured
Deliverability failure
Blacklist listing
Domain or IP listed on a blacklist
Messages rejected by recipients
DNS change
Record modified — authentication broken
Silent sending failure
Step by step
In a portfolio of many domains, sending domains need to be clearly identified so they can be prioritized.
What to check
Connecting the sending platforms to Infraova gives you additional context when issues appear.
What to check
With Infraova
With a sending platform connected, Infraova can associate infrastructure changes with the sending environment they affect.
Every sending domain should have SPF, DKIM, and DMARC actively monitored.
What to check
Sending domains are more likely to be listed on blacklists. Review blacklist status regularly.
What to check
You decide. Infraova executes.
Infraova can propose and execute an approved infrastructure change, but it does not independently decide to modify client infrastructure. Every proposed change requires explicit authorization before execution.
Key takeaway
Sending domains need more attention, not less. Identify them, connect their sending platforms, confirm authentication monitoring, and review blacklist status regularly.
