Sender is an email and SMS marketing platform built for small businesses, ecommerce stores, and SaaS teams. From one dashboard, you can run campaigns, build automation workflows, capture leads with popups, and send transactional emails. The drag-and-drop editor and prebuilt templates make it approachable for beginners, while automation triggers and segmentation give room to scale. A generous free-forever plan lets you send up to 15,000 emails per month to 2,500 contacts without a credit card.
