What Are Mailing Lists?

A mailing list is a collection of contact data including names, addresses, and sometimes demographics used to target specific groups of people for marketing campaigns. These can be physical addresses for direct mail or email addresses for digital outreach.

Mailing lists are typically divided into:

• ? Consumer Lists: Focused on households and individuals (great for B2C marketing)

• ? Business Lists: Ideal for B2B outreach, including by industry, company size, or job title

• ?? Specialty Lists: Custom-built based on unique filters like income, buying behavior, or geography

Whether youre running a postcard campaign, EDDM outreach, or brochure mailing, the success of your campaign starts with who receives it.
