Email Capture Tools: The Top 5 You Need to Use

Email marketing is one of the most effective marketing tools available because it results in high conversion rates and ROI. However, a stellar email marketing strategy is useless without an equally stellar email list. You need people to be on the receiving end of your email marketing campaigns. 

So, how do you get those people? Great question! The answer is simple: an email capture tool.  Email capturing enables you to legally collect email addresses from your website visitors to grow your email list and encourage further engagement with your brand.

There are various email capture tools available that enable you to incentivize your website visitors to hand over their email address. Whether you offer them a discount or free resource in exchange for their most valued possession (i.e., their email), you need a tool to help you create an attractive and effective form for them to do so.  

Now, if you type in “email capture tools” into Google, you will see a lot of different options. It can get overwhelming, mainly because not all email capture tools are created equal, and what works for one company may not necessarily work the best for you. 

That’s why we’ve created this top-5 list to review the best email capture tools so that you can choose the one that will be most effective for your company.
