Mailchimp is an email newsletter service which you can use to gather subscribers and send out email notifications for new posts. It is possible to gather up to 2,500 subscribers as part of their free account.
How to create a popup form
Many people like to display a signup form as a popup. Whilst this can be effective at alerting people to your newsletter, be careful not to annoy your readers by showing the popup too often or distracting from your content. If you would like to create a signup form which appears on the screen as a popup, Mailchimp have a guide for this feature on this page.
When adding the popup, Mailchimp will ask you to copy and paste some HTML into your site. You can copy this into the 3rd box at pipdig > Theme Hooks.
