How to Build an Email List: 4 Proven Methods

Building an email list isn’t easy but incredibly rewarding and valuable. Here are 4 proven list building methods:

1. Use a Database

Using a contact database is one of the most effective ways to build an email list. Lead generation tools offer these databases like UpLead and ZoomInfo. The databases tend to have millions of B2B contact email addresses. UpLead’s database has 155+ million emails.

Businesses pay for access to these databases, which they then use to build prospect lists. Sales and marketing teams will use these lead lists for their campaigns. They’ll be able to use features like search filtering criteria to make the data more granular and targeted.

A business should use a database if it can afford one and is ready to go to market. It’s the best option if you’re looking for rapid growth and have a good product or service.

2. Insert Opt-ins or Popups on Your Website

Opt-in forms and popups are useful tools to help build an email list. They can be featured in different places on a website, increasing the number of website visitors converting to subscribers.

For example, you might have high-ranking content that brings in a lot of traffic from Google. Adding a popup/opt-in form on this page will convert some of that traffic into subscribers.

A well-designed website will use opt-ins to build up its subscribers. You need to build an email list regardless of what your business sells. All businesses should at least use some form of opt-in. Popups are less needed, but they can be effective if done well.

3. Create a Landing Page

Creating a high-quality landing page on your website is an effective way to build an email list. A landing page is a single page designed to capture lead information, which is usually an email address.

Landing pages come in several formats, such as a content upgrade/lead magnet. An opt-in form on a blog post will lead to a landing page. This is where users must give their email addresses in exchange for something. A PDF, eBook, or checklist are common things.

Most businesses should use landing pages. They act as a way to maximize conversion and lead to more email subscribers.

4. Surveys, Quizzes, & Games

Surveys, quizzes, and games can be practical email list-building methods. Interactive content can increase engagement and lead to higher conversions. They can appear when users are on a website.

These types of interactive content are more niche. It might not make sense for a business to use them. It depends on the company’s type of business, industry, and market.
