Building an email list is one of the most effective ways for you, not only to promote your content but also to drive sales and in turn, grow your business.

The truth is that optimizing your website to capture email addresses isn’t always easy and without the right tools it can be incredibly time consuming.

In this post I will show you some of the most powerful list building tools on the market as well as the tools that will help you test and improve your conversions.

Develop Your Email List and Earn More

Research shows that two thirds of sales come from related emails rather than your web page. Put it a different way: you will sell three times as much and make three times the profit.

Email marketing is 20 times more effective than any other form of marketing.

Every $1 you spend on marketing to your email list can earn you $45 to $51 with email open rates of up to 30-40% being commonplace.

Growing Your List

Size does matter and if your list is close to non-existent, growing your list should be your first priority.


Getting people to sign up for your email list is the first hurdle you need to get over. There is a big problem here; research shows that 92% of viewers will click away rather than fill in a traditional sign-up form. You can use any of the tools later presented in this article to boost your sign-up rate.

You MUST get your readers over this first barrier. You have more obstacles to get over to convert your leads into paying customers, but for them this is the only one.

There are plenty of ways to optimize your website so that you help your readers get over this first barrier and subscribe to your email list, but it boils down to these 3 points:

  • Offer something of value
  • Make it easy
  • Make it relevant

Keeping it Going

At least 48% of emails are now opened on mobile devices. The first link in an email is 30% more likely to be clicked on if you use a responsive email template: Your emails must look good on a phone or tablet. There are email providers on the market that can help you. For example, GetResponse has a great set of tools including landing page templates and 500 responsive email templates that you can use to design attractive emails people will want to open whatever device they are using.

Your emails need to be useful or people will unsubscribe. Including exclusive money-off vouchers and offering valuable information are two very effective ways of keeping people on-board.

Opt-In Form Tools

You need to make it easy for people to subscribe to your email list and adding opt-in forms in key locations on your website is a great way to get started.

  1. I am using Leadin a free plugin to grow my email list and I think it is a very powerful free plugin. I stoped using SumoMe because free plan does not allow you to connect with MailChimp.
