Sender.net is an email marketing platform that allows users to create, send, and manage email campaigns, as well as send SMS messages. It offers various features such as drag-and-drop editor, email templates, automation workflows, segmentation, analytics, and integrations with popular tools. It has different pricing plans, including a free plan for up to 2,500 subscribers and 15,000 emails per month (https://www.sender.net/)
It would be really nifty to be able to link an Elfsight subscription form to Sender.net.
