Lusha shows a confidence indicator next to every email address to help you understand how likely it is that the email will be delivered successfully. This lets you prioritise your outreach based on data quality.

​
What the confidence ratings mean

  • A+ - the email address is highly likely to be delivered. Use A+ addresses for large or high-priority campaigns where deliverability and domain reputation matter most.
  • A - a good likelihood of successful delivery. Suitable for regular outreach where some risk of non-delivery is acceptable.
Email confidence rating shown next to a contact's email address
The rating appears directly next to the email address in search results, the extension, and contact tables - no extra steps needed to see it.
