OptinMonster vs. SumoMe vs. ConvertPlug – Which is the best list building tool?

When it comes to online marketing, email has proved to be a promising tool, often eclipsing all the other channels available for the purpose.

Email acts as a reliable podium to share news about new campaigns, special discounts and offers, or contents in a creative and personalized way. So, it is advisable to build and maintain an email list. It has been observed that 80-90% of the landing page traffic is brought by email marketing.

Emails also bring a better conversion rate your way since via emails, you can get direct access to a customer’s inbox, which is quite a personal space where one receives mails from family, friends etc.

No wonder that such messages shared via emails succeed in grabbing the attention of more customers as compared to any other marketing channels, often enticing many of them to visit your website and either signup for a newsletter, download an ebook, or buy from you.

To turn a random visitor into your blog subscriber or make him/her take an action you desire, all you need is to have a beautiful form on display and complement it with a juicy incentive to entice them into signing up. You can do the task easily with three tools namely OptinMonster, SumoMe and ConvertPlug.

Let’s do a comparative study to find out which one would give you your money’s worth.
