First of all, we will explore how to build email lists for free using social media. It is very easy to grow your email list through social media.

  • Bio
  • Profile
  • Pinned Post or tweets
  • Group posts etc.

Placing CTA on your social media profiles is the best location to get better clicks. For example, you can add a CTA button right after bio. Or in the most engaging pinned posts or tweets.

2Post/tweet Regularly

This interactive approach fosters engagement and facilitates the growth of your email list with interested and engaged members.

5Use Instagram Story

Obviously, yes.

Create your compelling lead generation website with all the key elements required for lead generation. 

Note: With a lead generation website, you can generate your email list at 2X speed.

9Create Landing Pages

Landing pages serve as single web pages designed with a clear marketing objective. They play a crucial role in acting as lead magnets, facilitating the growth of an email list through opt-in forms where visitors willingly provide their email addresses. 

Strategically implement CTAs, incentives, or persuasive triggers to captivate your audience’s interest and encourage them to join your email list.

For this instance, it’s essential to explore landing page best practices and master conversion rate optimization (CRO) techniques for creating compelling lead magnet landing pages and maximizing their effectiveness.

10Gate Your Best Content

Suppose you are successfully generating visitors through your website blog content. In that case, you can use this traffic to expand your email list. Take a look at the example below, where a website popped a form when I wanted to access their full blog. 

So, I simply filled out the form, thereby subscribing to their email list to read the entire blog. 

Gated Content Example

This method is highly engaging for obtaining email addresses. By offering your readers valuable content, they willingly exchange their email addresses. It’s a win-win situation: they gain access to valuable content, and you grow your email list organically.

11Leverage Exit Intent Pop-ups

OptinMonster states that exit-intent pop-ups can potentially convert 2% to 4% of visitors into sales. However, there’s a common sentiment among users that exit-intent pop-ups can be intrusive and annoying while browsing websites. 

The effectiveness of these pop-ups heavily relies on the content and visuals they present. If crafted with engaging and valuable content, exit-intent pop-ups can be a powerful strategy for building your email list for free. 

It’s essential to balance capturing attention and providing genuine value to ensure a positive user experience.

12Create a Homepage Sign-Up Box

A homepage is the first impression visitors have of a website. Ensure your audience gets enough engaging content or elements on your homepage to stay longer.

You can also add an engaging sign-up box right there so visitors can go through the sign-up box when they visit. And if they found it sign-up worthy, they might sign up, helping you grow your email list.

It is ascertained that the first fold section is the most viewed, so put the sign-up box there for maximum impact!

13Promote Your Gated Content

Promotion is an underestimated force in driving engagement. Your website’s evergreen content, which continually attracts traffic, should be gated and actively promoted across various channels.

When your evergreen content is promoted on social media or other platforms, it gets attention and draws visitors. When they see they have to enter their email addresses to read the evergreen content, they surely will. 

Without promoting your blog organically, you can gain visitors and subscribers but cannot rely on it. To maximize results, you must fuel your efforts with strategic promotion. By doing so, you can achieve the full potential of your content and attract a larger audience.

Building an email list for free from scratch can be challenging, especially if your online store is still in the preparation phase. However, some email list-building strategies may help you grow your email list.

15Run a Contest or Giveaway

Running a contest or giveaway is a great marketing approach for attracting visitors and growing your email list. A giveaway incorporating a contest can encourage participants to enter their email addresses.

The giveaway prize should be something relevant to your business and valuable but something everyone desires. Otherwise, you will end up with the giveaway with a broad, non-specific audience who may not be interested in your product or newsletter beyond the giveaway. This could lead to high unsubscribe rates post-giveaway. 

So, to run a successful giveaway, ensure you have an engaging contest and relevant and valuable prizes. 

16Offer Lead Magnet

Lead magnet is a powerful marketing strategy that helps marketers grow their email list. 

Through a lead magnet marketing strategy, you provide valuable incentives to your audience. In exchange, they allow you to send them your marketing emails.

  • Webinar etc. 

These incentives serve as valuable tools for engaging your audience and nurturing leads.

17Upsell Upcoming Product

Upselling strategy is mainly focused on boosting sales. But it also can capture email addresses while increasing your sales. 

For instance, if your business is gearing up to launch a new product or service, you can promote it with a “Notify Me When Launched” button. This approach helps generate interest and anticipation and enables you to collect email addresses from interested individuals.

19Use Opt-in Forms

Opt-in forms are the most transparent way to collect email addresses for sending marketing emails, making your product more trustworthy.

CRM (Customer Relationship Management) tools help businesses efficiently manage marketing, sales, and customer service functions.
