Agent rate limits
Give each agent hourly and daily sending limits so one runaway loop is delayed instead of burning the domain.
Protect sender reputation from autonomous email mistakes.
Stop runaway batches, invalid recipients, opted-out contacts, and over-limit mailboxes before they harm your domain reputation.
What it does
SendGuard treats every AI send as a preflight decision. It combines recipient checks, domain and mailbox age, daily limits, bounce history, suppression, and message content to reduce preventable bounces and complaints.

FAQ
Common questions
How is SendGuard different from bounce monitoring?
Bounce monitoring reacts after damage happens. SendGuard checks sends before delivery so risky messages can be stopped or reviewed first.
Can teams set different risk thresholds?
Yes. SendGuard supports policy profiles and contextual decisions so different teams and workflows can use different levels of strictness.
