Find a list provider: Search online for "mailing list providers," "mailing list by zip code," or "targeted mailing lists." You can also look in business directories.
Define your target audience:
Determine whether you want to reach consumers (residents) or businesses.
Specify your zip codes: Provide the list provider with the specific zip codes you want to target.
Add demographic or firmographic filters (optional but recommended): To make your campaign even more effective, you can further refine your list by adding criteria.
For consumer lists: You can filter by demographics such as age, income, presence of children, homeownership status, hobbies, interests, etc.
For business lists: You can filter by firmographics like benin phone number library industry (using SIC or NAICS codes), number of employees, annual sales volume, or years in business.
Get a quote and list count:
The provider will run a count based on your criteria to see how many addresses are available and will provide you with a price.
Choose your format: Lists are often available in different formats, such as an Excel or CSV file, or pre-printed mailing labels.

Complete the purchase: Once you've paid, you'll receive the list to use for your mailing campaign.
Important Things to Consider
Accuracy: Ask about the list's accuracy and how often it's updated. Reputable providers will run their lists through the National Change of Address (NCOA) database to ensure deliverability. A good deliverability rate is typically 95% or higher.
Pricing: Pricing is usually "per record" and can vary based on the number of records and the level of demographic or firmographic targeting you add.
Usage rights: Understand whether you are purchasing the list for one-time use or if it comes with a multiple-usage license.
Other services: Many list providers also offer other direct mail services, such as graphic design, printing, and mailing, which can be convenient for a one-stop-shop solution.
USPS Every Door Direct Mail (EDDM): If your goal is to reach every household in a specific postal carrier route within a zip code, the USPS offers a service called EDDM. This can be a cost-effective option as it doesn't require individual addresses, and you can still use the USPS tool to filter by demographics.
