Hi  {first_name} 

Looks like it's time to renew your white label domain's SSL certificate.This would explain the "connection not secure" notice when visiting your domain.

Why its important?

Web browsers give visual cues, such as a lock icon or a green bar, to make sure visitors know when their connection is secured. This means that they will trust your website more when they see these cues and will be more likely to buy from you.
