15 best email list-building services for ecommerce

September 12, 2023

Building and nurturing an email list is crucial for the success of any business.

However, building a comprehensive and accurate email list can take time and effort. Also, there’s no guarantee that the contacts in your list will convert.

So what can you do?

Well, this is where email list-building services can help you. These can help you build your email list and improve conversions from your email campaigns.

Luckily, we’ve done all the work and compiled 15 exceptional email list-building services to get you started.

But first, let’s discuss some key list-building tactics you can use to build your email list.

The main list-building tactics

Here are some of the most effective ways to grow your email list and engage your audience.

1. Popups

Using popups on your website is a great way to capture leads and build your email list.

Popups are like small banners or windows appearing in a web page’s foreground. They’re strategically designed to deliver specific messages and get users to take particular actions. 

This includes signing up for newsletters, making purchases, or accessing exclusive content. The users simply need to fill out a short form to provide their contact information to access the offer.

Popups allow you to collect email addresses of website visitors who might be interested in your products or services.

Here’s an example of a popup from Revolve.

2. Sticky bars

A sticky bar is a fixed, narrow banner often positioned at the top or bottom of a webpage.

You can use sticky bars to display important messages and promotional content to engage users. It encourages users to take specific actions without disrupting their browsing experience.

3. Landing pages

Landing pages play a pivotal role in email list building.  

A well-designed landing page offers a targeted value proposition. It encourages site visitors to provide their email addresses in exchange for valuable content or an offer.

There are several main use cases when merchants use landing pages:

  • Gated Content: These are used for resources like ebooks, reports, tutorials, etc. Visitors provide their email in exchange for access to the content.
  • Event-Specific: A laser-focused landing page designed for a particular event’s visitors.
  • Paid Advertising: Landing pages for paid ads and separate promotional campaigns often feature highly targeted copy and a call-to-action button.

Marketers typically create multiple landing pages to achieve the best results. Here’s an example of a landing page from Sunbasket.

4. Built-in forms

Built-in forms are a part of a website’s native functionality.

You can customize built-in forms to serve various purposes. This includes capturing user data, processing inquiries, collecting feedback, or facilitating user interactions.

Built-in forms make it convenient for visitors to subscribe as they don’t need to navigate away from the page they’re on. This frictionless experience increases the chances of capturing email addresses to grow your email list.

5. Surveys

Using surveys is a popular email list-building tactic.

You can simply add an option for respondents to provide their email addresses when they submit a survey response. This is a non-intrusive and straightforward way of building your email list.

Surveys work well when the questions align with the interests of the audience. It provides an incentive for users to willingly share their contact information.

6. Gamified forms

Gamified forms make the signup process interactive and enjoyable. 

They include interactive elements, such as quizzes, polls, or challenges. This helps you capture users’ attention and encourage participation. 

The element of fun motivates visitors to provide their email addresses willingly. That’s in exchange for a chance to win something, learn something new, or engage in an entertaining activity.

This dynamic approach boosts engagement and helps businesses gather valuable data. The data helps build a quality email list for targeted marketing efforts.
