How big is your email list? It's a hot topic in online business and a very necessary one too.

With more businesses moving online and social media algorithms constantly changing, having the contact information of current and potential customers and clients is more important today than ever before.

Mine is growing, but it's slow growing, so who am I to tell you about super charging your email list growth. Luckily, entrepreneur and podcaster Jenna Kutcher is an expert on this topic. In just over two years, she went from zero subscribers to nearly 75,000.

In a sentence, her advice is to grow your social media following, then convert your followers from your accounts to an email list where you can show up and serve them long before you ever sell.

Now, let's get specific.

1. Make it a more personal experience.

It's easy to feel like email marketing is speaking to the masses (and in a way it is). When you're collecting emails, make sure to grab the new subscribers first name so you can use it when you're reaching out.

"It's also important to share your personality and one easy way to do this is to include a photo of yourself when you invite someone to join your email list," Kutcher suggests. "I am a giant fan of creating visual connection. Including a photo can boost the number of people who subscribe because they are more likely to trust a human than just a company."

2. You have to give people a true reason to opt in.

You need to give people something they are willing to trade their email address for. That's the opt in.

Today, we are on the prowl to avoid as much junk as possible, so in order to truly grow your email list, you have to make sure that you're offering an opt in that is worthy of the exchange.

Jenna says asks yourself, "What do your followers need? What keeps them up at night? How can you create an offer that they will be eager to take action on?"

3. Grow a following of people that are excited to take action.

"It's not enough to put a pop-up on your website and call it a day. It's important to show up often in your followers feeds and serve them before you ask them to opt in," Jenna advises. "Poll your audience, share your expertise freely, and when you're ready, invite them to opt in."

Use a simple call to action in every single post on social media. Whether you're asking followers to like, comment, or even tag their friends, then when you have a new opportunity to opt in, ask them to follow the link to do so and explain the benefits. Make it impossible to resist!

"Social media should be a major part of your strategy because it gives people time to know, like, and trust you beyond your offers."

4. Run multiple opt-ins at once.

Share your opt-in weekly and in new ways. When people are launching an email list or trying to experience growth, a lot of times they will put a new opt in out into the world, share it once,e and then leave.

"The goal for opt-in is to create a freebie that is pertinent now and in the future--content that can continue to live on and be shared," Jenna says. "You should be sharing your opt ins in multiple places and pushing people to your different resources over and over again."

Whether it be through pop-ups on your site, in your Instagram posts, Facebook ads, or on podcasts, you can keep recycling your content over and over again so that it's continually growing your list.

"You have to have a strategy in place that has you constantly sharing and re-sharing it so that more eyes are on it," Jenna suggests.

5. Add an opt-in link to your email signature.

How many emails are you sending out each and every day?

"If people are in touch with you via email already, they are likely going to be interested in getting more content from you," Jenna says. "Have a simple call to action in your email signature and test it out. Every email you're hitting send on is a potential opportunity to gain another subscriber."

Email marketing isn't as scary as it seems. In fact, growing an email list is something just about everyone tells you they wish they had done sooner. So, what are you waiting for?
