Email verification should be an ongoing process, not a one-time task. Consider using these services in the following scenarios:
Before Sending Campaigns: Verify your email list before launching a new campaign to ensure high deliverability. Regular Maintenance: Regularly clean your email list to remove inactive or invalid addresses. After List Purchase: Always verify purchased email lists to avoid high bounce rates and potential spam traps. Sign-Up Verification: Implement real-time verification during the sign-up process to prevent invalid addresses from entering your list.
