Bulk email address verification – Melissa PH

Global Email Premium provides real-time email mailbox checking domain-specific logic as well as SMTP commands and other proprietary mechanisms to validate inboxes live. This can take up to 12 seconds per email address. Our built-in “time-to-wait” option allows you to customize how long you want customers to wait for a real-time validation.

Global Email Express sacrifices accuracy for higher speeds than Premium by using a cached inbox validation database of known good and bad emails. All emails sent to the service will also be cached so they can be re-evaluated within a 90-day cycle.
