Question: Is there a solution that can aggregate content from multiple sources like social media and websites, and format it into email newsletters?

Rasa.io is an email newsletter builder that uses AI to find relevant information from websites, YouTube, Facebook, Twitter and RSS feeds. It shows different information to different subscribers based on their interests, and it handles content aggregation, curation and delivery on its own. It's geared for businesses and marketers trying to increase engagement, retention and revenue with targeted and personalized emails.

Another good option is FeedOtter, which creates repetitive emails and newsletters quickly by linking and packaging content from a variety of sources like a CMS, website, feeds, articles and social media profiles. It's got a drag-and-drop interface, customizable layouts and integration with common Email Service Providers (ESPs). FeedOtter lets publishers free up time and get more use out of their content by automating mundane email creation.

For a more advanced option, Daily generates email newsletters with AI technology, including content curation, adaptive learning to optimize content based on subscriber behavior and branded voice synthesis. It also has human oversight for quality control and customizable content strategies to help you grow your subscriber list. Daily offers a variety of pricing plans, so it's good for businesses of all sizes trying to generate revenue without the manual content creation work.
