Email Validation is a vital part of any effective marketing campaign. Standard email validation companies rely solely on the process of SMTP negotiation to validate emails. There's a problem with this method - standard SMTP negotiation has never been able to provide a validation status on CatchAll emails or email servers using Greylisting techniques. Using standard SMTP negotiation alone, you receive no more information on the validation status of CatchAll, unknown and Greylisted emails than you had prior to running your list. Our 10 step email validation process includes pre validation steps, SMTP validation, greylisting techniques and the critical step of using publicly available information (registries, corporate bios, press releases, associations, etc.) and deliverability information to add intelligence around the validity of CatchAll and Greylisted email addresses.
