Email is a highly effective, personal way to build a relationship with an audience. It builds the trust and credibility. Your audience more likely to buy whatever it is you’r selling. The result is the conversion.

In my opinion, a great-looking optin form and a strong incentive to subscribe are prerequisites for generating email list optins — without this, why would anyone sign up?
You have a great-looking optin form and a compelling incentive. Is it enough to build an email list quickly?
No, that’s not enough to get maximum efficiency. There is a one important thing. Your optin form must be given maximum visibility on your website. The more visitors who view an optin form, generates more subscribers. It is simple.
According to my experience, the most effective way to gain subscribers is adding optin forms in key locations of your WordPress blog. Including pop ups, sidebar, below content area. It is the easiest way to get more eyeballs on your optin forms. Some of you might argue that pop ups are hurt user experience on your website. In my opinion, this is only true when they’re overused.
There are few other methods to achieve more productivity.
- Optin feature box
- Optin bars
- Automatic optin fly-ins
- Inline optin forms
- Require optin to unlock content
Placing optin forms in key locations is the way to go. With free list building plugins, it’s difficult to achieve better results. Therefore you need to invest some dollars for that. There are hundreds of premium list building plugins. So, you should choose a best effective WordPress email subscription plugin carefully. Don’t be afraid. I am here to help you the best solution for your needs.
