About SendFox

SendFox is a simple email marketing tool from AppSumo aimed at creators and solo businesses on a budget. It covers newsletters with a basic editor, automations for welcome emails and sequences, smart landing pages and forms, RSS-to-email, and integrations through Zapier and common platforms. Its pricing is the main draw: a free plan covers a starter list with a monthly send cap and SendFox branding, a monthly Pro plan scales with your contacts, and a one-time lifetime deal gives a fixed number of contacts and sends without a subscription. The trade-offs are clear: templates and the editor are basic, automation is limited, reporting is minimal, and deliverability and support are not as strong as on established platforms. It suits people starting a list who want to spend as little as possible and may move to a fuller tool later.

Best for: Creators starting a list who want the lowest possible cost.
