Buy or rent e-mail address files

Many companies offer email address databases for sale or rent. These lists typically fall into two main categories: individuals (B2C) and professionals (B2B). Some files may also be segmented by criteria like age, occupation, or postal code.

While buying or renting email lists is not inherently illegal, it's essential to verify that the addresses were collected lawfully. The recipients must have been informed at the time of collection that their data might be shared with third parties. Always ensure legal compliance before using any third-party list.

In general, rented lists are more reliable than purchased ones. Lists sold at extremely low prices — containing thousands or even millions of addresses — are often of poor quality and may have been collected unethically. Using them can damage your reputation and harm your email deliverability.

Email List Rental

Email rental is a safer alternative. In this model, you never receive the email list directly. Instead, you select a target audience, and the service provider handles the mailing on your behalf. These rented databases are usually well-maintained and used responsibly. Recipients can unsubscribe easily, and their data remains under the control of the provider — increasing transparency and compliance.

How Pricing Works

There are several pricing models used in email list rental:

For precise targeting

• CPT (Cost Per Thousand): You pay a fixed rate per 1,000 emails sent — the most common and straightforward model.
• CPC (Cost Per Click): You’re charged based on how many recipients actually click on your links.

For broader targeting

• CPL (Cost Per Lead): You pay per qualified lead, such as someone filling out a quote request form.
• CPA (Cost Per Action): You pay only when the email generates a specific result — like a sale or sign-up.

Beware of Email Harvesting Software

Some companies sell software that automatically scrapes email addresses from websites and directories. While this might seem like a quick way to build a list, it's a dangerous practice. These tools collect all visible emails indiscriminately — including personal and unauthorized addresses.

Important: In most regions, sending unsolicited emails to individuals without their prior consent is considered spam and is illegal. Even in B2B settings, emails should only be sent to generic addresses like [email protected] or [email protected]. Targeting personal addresses (e.g. [email protected]) without permission is strictly prohibited.

Instead of relying on risky methods, learn how to build and maintain a clean and compliant mailing list.
