MAILING LIST and EMAIL LIST HYGIENE

NCOA

Mailer Warehouse's NCOA service updates your mailing lists with a new address for anyone who has moved within the past 48 months. Mailer Warehouse will update your mailing lists using the US Postal Service National Change of Address (NCOA) database going back 4 years
If you plan on doing any type of mailer you should always NCOA your mailing list to avoid expensive postage and printing costs sending mail to old, outdated and undeliverable mailing list addresses.
You should also NCOA lists prior to appending phone numbers or email address appending to maximize the number of matches you receive. The more accurate the list, the more matches you receive.

CASS / DPV / LACS

No, we're not playing alphabet soup. These acronyms from the U.S. Postal Service have a lot of meaning if you’re a mailer. Address cleansing is getting more precise, which means better mail deliverability.

The US Postal Service's Coding Accuracy Support System (CASS) evaluates the accuracy of data-cleansing. CASS-certification is available to all mailers, service bureaus, and software vendors. What exactly is CASS?

On August 1, 2015 the USPS began Cycle L of certification. It requires the use of DPV and LACS technologies when processing address lists. Each cycle, or round of certification requirements, lasts a year. Each year, the new cycle raises the bar for quality within the CASS certification process by implementing new technologies and requirements in the address matching software industry.

DPV -- (Delivery Point Validation)

DPV validates each address against the more than 145 million delivery points (deliverable addresses) on file with the USPS. It determines that either the address has the correct primary and secondary data, the address has the correct primary but not secondary data, or the address cannot be validated.

LACS

LACS automates the retrieval of new addresses that have been converted by local municipalities, usually when the community has implemented a 911 emergency system. 911 address conversions normally involve changing rural-style addresses to city-style addresses, but in some instances municipal conversions may result in the renaming or renumbering of existing city-style addresses.

EMAIL ADDRESS VERIFICATION

Scrub old undeliverable email addresses from your
email lists with our email address verification service.

If you are using a commercial email sending company that charges you a set price per number of emails sent, then it is in your best interest to scrub out all the bad email addresses from your email databases. This will keep your bounce backs and undeliverables to a minimum and save you money.

How Does email verification work?

Email addresses are like fruit... they tend to go bad after a while. People change ISPs, ISPs close down, people change domains and forget they still had old email addresses on web pages and online directories, etc.

It is estimated that up to 30% of emails become abandoned, obsolete and undeliverable each and every year.

It's not uncommon to have a so-called "fresh" email address list that contains up to 50% invalid email addresses! If you send your emails to a list like this, 50% of your effort would be wasted on attempting to deliver to undeliverable email addresses (not to mention having your inbox filled with undeliverables).

Our Email validation service will verify and clean your email lists to drastically reduce bounce-backs and eliminate "mailer daemon" email bounce-backs from your filling your mail box.

Email list hygiene is essential to avoid ISP's mail servers black listing you for repeatedly sending emails to invalid email addresses or receiving too many bounce-backs.

Email verification keeps your email address lists up to date. The email validation software doesn't send an actual email to verify that email address. It creates a direct connection to the email server to check the validity of the email address without actually having to send an email.
