It is possible to append email addresses to direct mail lists.  All you need is a list of names and addresses and Action Mail can append email addresses to your database.

Match rates are typically about 20%, but it depends on the list, and it is only possible to know the match rate once the list has been processed.  The email addresses we match have opted in to receive marketing emails.  Yet, this does not mean it is appropriate to use these email addresses to send email blasts.  Many email providers ban the use of purchase lists on their platforms, and if you send bulk emails from your own account it is probable that your server will be black listed for sending spam.

Action Mail typically recommends the use of appended email addresses for matching the email address with an IP address or account, so that you can target the individuals through banner adds or social media marketing.  We have also seen people use these lists to send individual emails as opposed to researching and looking for each email address, though this will need to be done carefully to avoid spamming individuals and having a server blacklisted.

We recommend that appended emails be used to target individuals solely by matching the email address to an account or IP address.  Success with email appened data really depends on how it is used and the expectations and understand on what should be done with the data
