Loops

Loops blurs the line between marketing and transactional email by offering both in a single platform, with a generous free tier for transactional sends. You can use it for newsletters and promotions on your marketing list, then send password resets, notifications, and receipts to the same platform without switching tools or paying extra per transactional message. It includes audience segmentation, automation flows, and templates designed for both message types.

This appeals to growing SaaS and web apps that want to keep email simple without managing multiple vendors. The free transactional allotment on paid plans makes it cost-effective for small to medium volume, and having one interface for both email types reduces operational overhead. Teams with very high transactional volume or complex subscriber segmentation between marketing and transactional might outgrow it or want the specialization of dedicated platforms.
