# Cru Policy on Bit.ly Links

### Prohibited Use

Bit.ly URL shortener links are prohibited for any emails using Cru IPs in the sending process.

### Reason

Use of Bit.ly links results in a "ReturnPath Certification" violation.

### Consequence

Violations lead to Cru emails being blocked due to the lack of certification whitelisting.
