The best thing about Mailpoet is that you don't have to leave your WordPress dashboard to run any of your email marketing campaigns. It helps you keep your audience engaged with super easy-to-use ready-made welcome emails, newsletters, and notification templates. This plugin makes it easy to automate and schedule emails for every action your audience takes on your website, such as welcome emails for new signups and post notification emails when you publish a new blog post. Now they have also launched templates for wooCommerce stores, for example: Cart Abandonment Emails or whenever users make their first purchase, etc.

If you don't ever plan to grow your subscriber base beyond the 2,000 mark, then MailPoet may work well for you. It's free and pretty easy to build a newsletter.

All in one integration with wordpress websites.
