Best WordPress Optin Plugins to Grow Your Email Subscriber List

Best WordPress Optin Plugins to Grow Your Email Subscriber List

It’s one thing to have great content on your website, or even have a fantastic newsletter, but there’s no point investing time in creating content if no one’s reading it.

One of best ways to get visitors returning to your site or reading your newsletter is with an opt-in form. Optin forms allow you to collect email addresses so you can alert users when you have new content or offers and get them to return to your site.

There are a bunch of different kinds of ways you can display opt-in forms on your site (sidebars, slide-ins, after post boxes, and squeeze pages) and you can even choose when these forms are displayed (after a specified amount of time or when they’ve scrolled to the bottom of your site).

You can also integrate many optin plugins with major email marketing services, such as MailChimp and Aweber.

Adding an optin form to your site is easy and will help you increase traffic to your site, convert new visitors, and better engage with return ones.

The plugin list below is short because I’ve picked the best plugins for the job. I’ve specifically chosen free and premium plugins that include email marketing integration and some other features like form customization, A/B split testing, and analytics.

  • SumoMe - List Builder, Scroll Box and Smart Bar (Free)

    The team behind AppSumo, a daily deal site for software, have made available a suite of free tools they used to build their email newsletters to over a million subscribers.

    Their sister site, SumoMe, features eight apps. In this listing we’ll look at just three – List Builder, Scroll Box and Smart Bar.

    List Builder allows you to create simple and elegant lightbox pop-ups that can be customized to automatically pop-up after a certain amount of time, or you can use “smart mode” to ask your visitors to subscribe as they’re about to leave your site.

    Scroll Box adds an optin form to the bottom corner of your site and slides out as visitors reach the bottom of the page. The plugin is fully customizable, so you can set at what point on the page you want to ask your visitor’s for their email address, how often is is shown and where it is positioned on the page.

    Lastly, Smart Bar places a bar at the top of the page where visitors can enter their email and sign up for your newsletter. It features three options for display: when a visitor scrolls up, scrolls with the page, or always stays at the top. It also comes with five custom themes, or you can customize how it looks with HTML.

    All of these plugins feature easy integration with MailChimp, Aweber, Constant Contact and Campaign Monitor.
