Don’t count out Email marketing for a second. Just because it’s not the fancy new thing doesn’t mean it doesn’t dominate when it comes to ROI. In fact, email marketing earns an average of $40 for every $1 spent.

Let’s face it, that’s the ROI that marketing dreams are made of. And it points to what amounts to a missed opportunity for many businesses. If you’re not actively growing your email list, you’re missing out on one of the best, most cost-effective ways to grow your business.

And here’s the thing. Growing your list doesn’t have to cost you a ton of money. Here are 7 smart ways to attract new subscribers.

Facebook continuously provides businesses with free features that help promote your business. Facebook now allows businesses to add a Call to Action button on their page. There are six choices, but the one we’re focusing on today is the “Sign Up” button.

The button shows up on the right-hand side of the page just beneath your cover photo. Clicking it will redirect visitors to a URL you provide. In this case, it should be your opt-in page. That’s where you can display information about your list and ask people to fill out the opt-in form.

On a related note, you can run a Facebook ad with a “Sign Up” button too, and it will do the same thing. If you choose the ad, you’ll have to pay for it. But, it’s a cost-effective way to attract new subscribers.

This next idea is one of the oldest tricks in the book. People who walk into your business may be willing to take a minute to provide you with their name and email address if you make it easy for them to do. And what’s easier than a paper sign-up sheet?

If you choose this option, make sure to include a few

lines at the top to tell people why they should subscribe to your list. For example, saying “Sign up here to be the first to know about our upcoming sales and promotions,” people will understand what they’re getting. Even better, they’ll be eager to sign up.

An alternative, of course, is to have your cashiers or other staff ask people for their email addresses when they check out.

The best way to get people to subscribe or sign up for something is to make it as easy and low effort as possible. People don’t want to waste their time filling out a lengthy or complicated form. So, why not let them text to subscribe?

Some email marketing providers are now offering a text to subscribe option. It allows mobile users to text the word “subscribe” to them, and they’ll be added to your email list. What we love about this method is that it takes only seconds to do.

This option works by creating a custom code for new subscribers to use. To make it even easier, you can display a sign in your store with the code so people can see it and act on it immediately.

Use every opportunity to collect emails and personal information. Whether you’re putting together a charity fundraiser or a gala opening, you can use the opportunity to collect email addresses and grow your list.

The great thing about this option is that you’ll probably need to ask people for their email addresses anyway. You may need it to send them tickets or

updates about the event. Simply adding a checkbox to your event sign-up form makes it a snap for attendees to opt-in to your list at the same time.

The key here is to make sure you describe your list briefly, so people know what they’re signing up for. You want to make it seem like a no-brainer for people to tick that box.

The idea of creating a lead magnet isn’t new – but if you aren’t doing it, it’s new to you. A lead magnet, in case you don’t know, is a freebie you give people to entice them to subscribe to your list.

The key is to create a lead magnet that appeals directly to your target audience. Then, you need to sell it hard. Outline the primary benefits that subscribers will get if they opt in. The more enticing your lead magnet is, the more likely it is that it will help you supersize your list.

Keep in mind that a lead magnet doesn’t have to be worth a lot to be worthwhile. A well-designed tip sheet or template may be just the thing to bring in a slew of new subscribers.

You don’t necessarily need a dedicated opt-in page to get people to subscribe to your list. Sometimes, it’s enough to create the perfect opt-in form – and place it perfectly on your page.

One option that I really like is the scroll-triggered form. Instead of putting your form above the fold, as many marketing experts tell you to do, show it to site visitors after they’ve had a chance to read some of your fantastic content.

A form that shows up at the right time can catch readers when they’re impressed with your expertise and grateful for what they’ve learned by reading your content. At that point, they’ll be happy to give you’re their email address in return.

Do you allow guests to access your wi-fi? If so, adding a gateway to their access can make it easy to collect email addresses.

Instead of just giving guests the password, add a field to the form and request their email address as well. Even if you make the email field optional, most guests will be happy to provide their email address to use your wi-fi.
