Why is email marketing so effective?

Email marketing is a digital channel that consistently outperforms almost every other one. You can expect to see an ROI as high as 40:1. The most successful businesses incorporate email marketing as a central pillar of their marketing plan. 

Part of the reason the ROI is so high is due to email marketing’s versatility. You can test offers with specific segments of your list, onboard new users, launch brand new products, and much more.  

With SEO, social platforms, and native ad placements, you’re limited in many areas. You’ll be lucky to see a 3:1 return on investment. The direct ROI from email marketing is just one reason you should be collecting email addresses. There are many others. 

A regular newsletter where you promote blog content, company updates, and interesting industry news extends your reach. If the content you’re promoting is good, your subscribers will share, link to it, and forward it to their friends. 

You’re also able to build a deeper connection with subscribers. As long as you keep an eye on deliverability, scrub your list regularly, and segment based on behavior or psychographics, you’ll be able to turn casual visitors into your biggest advocates. 

None of this is possible if you don’t collect email addresses. 

How to collect email addresses (and what you need)

There are countless ways to collect contact details. The methods you choose will depend on your business and goals. 

For example, if a business has multiple brick and mortar retail locations but doesn’t sell online, they’d focus on collecting email addresses in-store. That could even mean old fashioned pen and paper or typing in at Point of Sale when a customer checks out. 

Though it can be effective, it’s not the most scalable method. Instead, we’re focusing on collecting emails digitally and online. There are multiple ways such as:

1. Popups

The simple truth is that popups work, that’s why they’re so popular with results based marketers. The key is to use them at the right time with the right message. Content upgrades are a great way to reduce the perceived annoyance and boost your conversion rate.

Here is an example pop-up for list building that goes perfectly with the content. The content makes people want more and they get more (not even a direct value, but getting on the waiting list for a training). 

2. Landing pages

A landing page is any page a visitor lands on. In our specific use, a landing page is a page a visitor lands on that is designed to get them to take your desired action (capture the email address). So the distraction should be minimal. Minimal navigation options, focused design elements, and a clear call to action (CTA). 

Landing pages can be used to sell digital products, collect email addresses, promote app installs, promote your podcast episodes, and everything in between. This article we focus on list building software, not per se landing pages – but if you are running ads, promoting a download or using paid media. Keep in mind that the landing page is where the “magic” happens.

3. Inline opt-in forms

Inline opt-in forms are a great compromise between disrupting visitors with your popups and achieving your list building goals. Instead of appearing instantly or after a set timeframe and obscuring the page content, they’re embedded within the page content. So when you scroll down, this list building tool appears naturally in-content.

Here is a list building example with a twist. A variation of the inline opt-in form is the content locker. A content locker hides media and text on a page until the visitor performs your desired action. This could be anything from sharing the post to subscribing to yoru newsletter. 

4. Sticky bars

Sticky bars, also known as floating bars, take up a small portion of the bottom or the top of the screen. It doesn’t obstruct the content and has just one line of space to deliver your message. They’re ideal because users can leave them on the screen and still interact with the content they came for. Typically they have bright color, to set them apart from your page header.

5. Interactive quizzes

Interactive quizzes are the new kid on the block when it comes to email list building. Instead of simply asking people to sign up for your newsletter, a quiz gives you the ability to engage with and segment subscribers first.

After they’ve gone through your quiz and had a few micro-commitments, they’re more likely to sign up for your mailing list. This also plays into the sunk cost fallacy which is part of the reason why people spend more money or time on projects that aren’t yielding fruits. 

6. List building Surveys

A survey is an indirect method for capturing email addresses. Whether you can use them as an email capture tool depends on the type of survey it is and the reasons behind it. For example, if a business sends out a market research survey, it may offer an incentive that can only be redeemed when someone leaves contact information.
