Great question! Here's a quick breakdown of what's currently available:

Delivery Status
If you connect your Gmail or Outlook account via the Integrations menu, emails you send will also appear in your personal Sent folder. You'll receive standard bounce-back or delivery error messages there, which is the most reliable way to catch invalid email addresses.

Open Rates / Read Receipts
Not currently supported for individual emails. Modern email providers actively block open tracking to protect user privacy, making it inherently unreliable on a one-to-one basis. We do use tracking pixels in newsletters, where the data is more useful across larger samples, but we wouldn't recommend relying on pixel tracking for individual emails on any platform.

Link Clicks
This one you can track! Check the Activity tab on a contact's profile to see if they've clicked any links included in your emails. This is actually a more reliable engagement signal than open tracking.
