When to add IP reputation monitoring

Domain authentication alone does not cover every reputation signal that affects delivery.

You may need IP monitoring when

• Multiple dedicated or shared IPs send for the same brand.
• Volume ramps quickly on new infrastructure.
• Blacklist or deferral alerts reference IPs more often than domains.

What continuous IP checks add

• Faster detection of IP-specific listings.
• Trend visibility across your sending pool.
• Clearer prioritization when domain and IP signals diverge.

Start with the IP tier that matches your check frequency needs, then scale slots as your pool grows.
