Click-through rate
The email’s click-through rate shows the percentage of recipients who clicked on a particular link within an email message.
Conditional blocks

Domain name
A domain name is a label that identifies one or more IP addresses. A top-level domain is the broader designation whereas a second-level domain is more specific.
Domain Throttling
Companies are often limited on the number of emails that can be sent to a single domain in a short space of time. To evade spam filters, some companies will use this technique.

S
Segmentation
