Percents next to email addresses:
When RocketReach has been unable to confirm the validity of certain emails (for reasons beyond our control), we will still include them for reference along with a confidence score (displayed as a percentage). In these cases the emails may bounce, but the likelihood of bouncing is lower for emails with higher confidence scores.
For example: In the screenshot below, firstname.lastname@example.org is more likely to be correct than email@example.com.
Red email addresses:
Email addresses shown in red are determined by RocketReach to be invalid, and will bounce. They have only been included in your search results for reference.
