Custom Opt-In Form plugin allows you to add custom opt-in form into your posts and pages to collect visitors’ contact details. The plugin has internal autoresponder so everyone who submits their name and e-mail will receive message defined in plugin settings page. The plugin is useful for landing pages based on WordPress. You can easily integrate custom opt-in form into any posts or pages. You only need to insert the following code into their body: [opt-in-form]. If the user decides to submit his/her contact details, they will be sent to server without refreshing the page (using AJAX). After that autoresponder sends e-mail message (with attachments, if required) to visitor’s e-mail address. Content of this message and attachments are set by administrator. Please try opt-in form above to see how it works.
