concatenated |
Linking together fragments of known customer data, such as name and company website information, in spreadsheets or databases to create or obtain email addresses. | |||
|

Matching known customer data, such as name and company website information, against vendor databases to create or obtain email addresses. | |||

|

Lead Gen & CRM expects customers to only email recipients who have expressly opted in. This means that purchased, rented, and scraped data does not meet this standard. This policy is in effect because purchased lists do not respect recipient inboxes.
As such, purchased, rented, and scraped lists are considered spam by the email community. These lists cause serious deliverability issues for both individual senders and Lead Gen & CRM's network as a whole. By prohibiting purchased, rented, and scraped lists, this policy protects you—as well as the rest of Lead Gen & CRM—from blocklisting and poor deliverability.
Purchased lists are:
Lead Gen & CRM does not recommend using email verification services to bypass permission. List and email verification services may be part of list maintenance, but they do not guarantee that your sent emails will arrive in the inbox. Since list cleaning services only check for the validity or the otherwise bad status of an address, they cannot convert email addresses into directly opted in recipients, which is the standard for using recipient lists in Lead Gen & CRM. As such, you may want to consider list verification prior to emailing older lists or to gauge the quality of recent sign-ups.
Often, when senders have cleaned their lists with these services, they still have poor inboxing rates. Some emails are outright blocked by anti-spam applications that recipient email servers put up. At this point, it is not that these senders' lists are clean enough. Rather, these senders need to review:
In fact, the most important thing in sending email is permission. With proper permissions and a good sunsetting policy, you may never need to have your list cleaned by a third-party service.
Lead Gen & CRM helps customers by only advising to send to recipients who have expressly opted in. Starting with good permission, you just have to clean your list incrementally by removing bounced addresses, spam complaints, unsubscribes, and unengaged recipients as part of your own ongoing list management. Senders practicing such list management have consistently excellent deliverability.
