As a B2B marketer, I have learned that sourcing a quality list is an art. As marketers we have the ability to rent or purchase e-mail, telemarketing or postal lists. But, we must determine which vendor guarantees a high-quality and targeted list source.

Here are a few things to keep in mind when sourcing a list:

1. Lists are very expensive, so have a specific list criteria and targeted regions in mind.
2. A good vendor should be able to sort a list by a specific industry or product/service interest.
3. Be sure your e-mail/postal/telemarketing lists match if you are renting or purchasing more than one type of list.
4. There are some vendors that do not allow you to purchase a list, but they do allow you to rent a list. In this case, have a well-developed campaign to guarantee a good response rate.
5. Renting a list means you have to send your artwork to the vendor and they will send it out on your behalf.
6. When renting a list, the standard distribution rate of an e-blast is one transmission unless you pay additional transmission fees.

Now, you might be wondering where to source a list…we have found that Corpdata is a great list source if you are looking to purchase a list, and TechTarget is a good vendor to use when looking to rent IT leads.
