By surfacing domain health, mailbox performance, and engagement trends across your users, the deliverability suite helps you safeguard your team's outreach and drive more consistent pipeline results.

Apollo only shows email tracking data if you have enabled open tracking or click tracking on the selected mailboxes. You should only use open or click tracking if you have a custom tracking subdomain and understand email deliverability best practices. Even then, it's important to use email tracking as part of a targeted, time-specific campaign, then deactivate tracking once complete to protect your domain reputation.
