The Importance of a Big, Healthy Email List

But first, I want to quickly explain why having a big, healthy email list is so important for almost any brand, regardless of the industry.

For starters, having a large email database gives you direct access to your audience, taking out the volatility that can come from relying on social media algorithms, varying PPC costs, and the dreaded Google algorithm updates.

You own the channel, which means you have complete control of what gets sent to your audience, when it gets sent to them, and how your messaging is viewed.

Additionally, the ROI for email is significantly better than other marketing channels. According to The 2025 State of Marketing Report, the average ROI for email marketing campaigns is 36 times. That means you can earn an average of $36 in pure revenue for every dollar you spend on your email marketing efforts, a return that other marketing avenues can only dream of!

6 Ways to Build and Grow Your Email List Without Paid Ads

As you can see, there are a ton of reasons why you need a large active email list. However, founder budgets are often tight, so any opportunity to save on outreach should be snapped up with both hands! With that in mind, here are six tried and tested ways to build and grow your email list without the need for paid ads.

Give them what they want

One of the most successful ways to build your email list is through giveaways. Sometimes, you’ve got to give a little to get a lot.

However, if you don’t have the marketing budget to give away an expensive prize, you could also do so by providing something for free, such as a checklist, template, mini course, or even an eBook.

Strategic sign-up placements

It’s easy to focus on the content of your email opt-ins, but it’s also just as easy to forget about the placement of them.

Don’t just limit your email opt-in messaging to a singular place on your website. Consider adding it to your homepage, any blog posts you publish, your website footer, about page, and even via pop-up messaging.

Run a free challenge

Another excellent way to engage your audience and build trust is by inviting them to a brand-specific challenge or boot camp. These experiences feel interactive and valuable, and the only investment required is your time and expertise.

For example, if you run a wellness brand, you could host a 7-Day Wellness Reset Challenge, helping participants improve their energy, focus, and overall well-being.

Don’t be anti-social

Speaking of social channels, why not turn followers into subscribers? These people are already actively engaging with you on social media, so there’s a good chance you could convert them into email list subscribers as well.

Add your email link…everywhere

However, your social media bio shouldn’t be the only external avenue you use to get your email opt-in link out there! There are also tons of other locations you can add it without damaging the consumer experience, such as your email signature, LinkedIn bio, your business cards, and even as part of a guest post outreach strategy.

Collaborate

Lastly, building your email list as an entrepreneur can feel like a very daunting task, and one that can seem hard to do as a solo effort.

But it doesn’t have to be a solo effort!

There are a ton of other entrepreneurs out there who will be interested in collaborating with you, sharing their audience with you in return for you sharing yours, a total win-win.

How to Make the Most of Your Email List

Now you have all the free tools and tactics you need to grow your list. Don’t expect this to happen overnight, but a prolonged and multichannel approach will certainly gain traction over time.

However, it’s essential to also consider what to do once you have grown your email list. After all, it’s one thing to grow your list, but it’s another to keep them engaged and excited about what you send them.

To cover this topic in great detail, we probably need to create a whole new article, but here’s a quick breakdown of the most important things to consider once your list has begun to grow:

  1. Nurture, don’t just sell: People join your list for value, not just sales pitches. Focus on building a relationship with educational content, personal stories or behind-the-scenes, curated resources, and thoughtful opinions.
  2. Segment your audience: Not all subscribers want the same thing. Group your list by interests, purchase behavior, and (most importantly) engagement levels.
  3. Automate your welcome series: When it comes to a great email setup, triggered communications are your best friends. A welcome series is the perfect place to start, as he first few emails you send help set the tone and manage reader expectations. Create a welcome sequence that introduces your brand, provides instant value, sets expectations, and builds anticipation.
  4. Track what works: One thing I was taught at the start of my email marketing journey? You should always be testing something. Use your email platform’s analytics to monitor open rates, click-throughs, unsubscribes, and conversions, and don’t be afraid to test and try new things.
