INBOX

Email marketing platform for campaigns, automation and newsletters

Visit INBOX

INBOX is an email marketing platform that helps small businesses and organizations design, send, and analyze campaigns while managing subscriber lists and compliance across multiple regulations. It brings newsletter creation, automation, and audience growth tools into a single account, alongside transactional and cold email capabilities.

Core features include a drag-and-drop newsletter editor with ready-made templates, marketing automation scenarios, A/B split testing, auto resend campaigns, landing pages, signup forms, segmentation, and campaign reports. Transactional emails can be sent via API or SMTP, and an MCP server connects AI assistants such as Claude to account data for drafting content and analyzing performance. The platform also supports multiple domain management, multi-user access with different permission levels, and integrations with external apps.

INBOX is aimed at marketers, business owners, and teams that need to run email campaigns without deep technical setup. It offers a free plan with no credit card required, alongside monthly subscriptions and pay-as-you-send credit packages; plans can be upgraded or downgraded as needs change, with no setup or license fees.
