Email Certification and Accreditation

Email Certification and Accreditation is a service that third party independent companies provides, these companies have special relationships with many of the ISP providers (HOTMAIL, AOL, COMCAST, etc.) and many different spam filtering companies (SPAM ASSASSIN, etc.) that allows emails to bypass some of the spam filtering that every email goes through. They are trusted members of the email community and these companies will work with you to get your company certified based on their criteria. Once your company is certified you will be listed as a member of their organization (for a monthly fee).

Why does Email Certification cost money?

Well you can try to establish relations with the many and ever-growing number of ISP and Spam Filters or you can save yourself the headache and sign up with one of the third-party accreditation services that already have those relationships in place for you and dedicated staff to ensure those relationships stay in place. If you’re a company that sends bulk email of any kind (newsletters, forum subscribed post updates, daily automatic emails, etc). You should definitely look into services like these and choose the best one that fit your needs.

Are these email certification services really worth it?

Well that’s an easy question, but you don’t have to take it from me, take it from companies like Godaddy, Groupon, MailChimp, SendGrid, Constant Contact, and countless others. Their businesses are very dependent on sending emails and they all signed up with the third party accreditation services. These services companies have a huge portfolio of large and small clients and there’s a reason for it. Having the best deliverability rate impacts your bottom line.
