It’s no secret that email list building is crucial for any business.
And anyone with any website knows the importance of list size when it comes to email marketing campaigns and outreach efforts.
The problem is that it can be time-consuming and difficult to grow your list in the first place – especially if you’re not already an established brand or company with a sizeable following on social media sites like Facebook and Twitter.
Thankfully, there are some list building tools that can help.
Today, I’ll run you through 9+ email list building tools that your business can utilize to help grow your email address database, while also providing tips on how to make these tools work for you.
Let’s dive in.
How do you build a list?
List building is the process of growing your list of subscribers on an email list.
As your list grows, you are able to engage with a wider audience, increase conversions from email marketing campaigns, and grow your brand awareness in the process.
When it comes to list building – there are two main approaches: organic growth or paid acquisition.
Organic growth is all about ranking on Google and directing your audience to the list sign-up form on your website.
Paid Acquisition on the other hand involves using tools like Facebook Ads and Google Adwords to find potential subscribers and customers that fit into specific criteria around demographics, interests, etc.
Both have their own pros and cons, but they can be very powerful when combined together. Here are some list-building strategies and ways to optimize your landing page sign up forms:

- Build everything easily and quickly. The OptinMonster plugin makes it easy to set up even for those without any knowledge of coding. Their drag and drop editor also makes it especially easy.
