I often refer to MailerLite as ActiveCampaign Lite. It is a great starter email marketing platform for both product and service based businesses.
It is simple, affordable and easy to use and offers a drag & drop editor, landing pages, embedded & pop-up sign up forms, email automations with advanced segmentation, ecommerce integrations and even embedded surveys.
