a hard bounce. That's why you want to use QuickEmailVerification, a real-time email verification service. The ActiveCampaign+QuickEmailVerification integration verifies email addresses in real time. Each time a contact is added to your ActiveCampaign list, a chain of actions is triggered. The sophisticated algorithm puts the email address through a series of tests to see if it is valid.
If the email address turns out to be invalid, it is rejected. But there is more. Although verifying the validity of the email address is the industry leads most important part of the integration, it is not its only capability. Some valid email addresses are also risky. A role address (e.g. support(at)somedomain(dot)com) is a shared address, so you won't get engagement. A temporary email address is not invalid in the conventional sense but the user will never use it again. Again, no commitment.
This integration tests both the validity of email addresses and the quality of the email address, and tags each address accordingly. This is to ensure that you only send emails to high quality, deliverable email addresses. How QuickEmailVerification and ActiveCampaign work together The integration performs a simple yet extremely important function: qualifying and validating email addresses to dramatically improve your email deliverability.
