Email marketing is still one of the most effective ways to increase sales, giving you a chance to send special offers, interactive content, and updates about your products directly to consumers.
Checking email is a daily habit for most of us. And ecommerce stores can become a part of this routine if their email subscribers get used to seeing and opening their marketing messages. In fact, a whopping 50% of people buy from marketing emails at least once per month!
It’s clear that building a huge email contact list should be a priority. To do that, you’ll need to find a good email list building tool. List building software helps you collect email addresses via landing pages, opt-in forms, and lead generation popups.
In this article, we’ve collected 12 of the best email list building tools out there. When used properly, these marketing tools can bring in a steady stream of new leads.
Let’s get started on finding a great list building solution!
How to capture email addresses and build a list?
There are many list building strategies that can boost your lead generation rate. These options include using dedicated landing pages to capture email addresses, embedded email opt-in forms on your website, and popups that display an opt-in form.
These are all great ways to build an email list, and we suggest using a combination of these proven tactics.
But what’s the best way to generate high-quality leads?
Remember, it’s not all about size. Sure, a massive subscriber list is great, but what’s even better is a massive list that only contains interested, engaged subscribers. If you’re looking for a list-building method designed to attract lots of people who are genuinely interested in what you’re offering, there’s only one way to go: popups and other on-site messages.
Collecting email addresses from your website visitors generates high-quality leads because those visitors already have an awareness of your brand and products.
And popups work much better than simple inline forms, because you can precisely target people with great offers at just the right moment. They also help to focus the visitor’s attention on a single, enticing offer, thereby simplifying the decision-making process.
Our studies show that the average popup conversion rate is 11.09% (and that the top 10% are converting at around 42%, on average). Those astonishing numbers are the result of brands that create well-timed popups that are perfectly optimized for lead generation and grab their visitors’ attention. It’s difficult for embedded forms or landing pages to achieve conversion rates like these.
Exactly which types of popups you should use to collect email addresses depends on your brand and what your website visitors respond to. You have lots of options, including welcome popups, exit intent popups, discount popups, and lucky wheels. Check out this article for an overview of all the types of popups that are out there.
