To make your blog look more professional and user-friendly, a lot of small services can be used. Blog Plugins are by no means cheap. And for a new blogger, shelling out money seems a little confusing in the beginning. One such service you need is subscription box or an Opt-in box. It can help entice and interest your reader in sharing their email address with you.
I found two free options in the market that are awesome for being free and highly customizable.
