# SendFox

> SendFox is an affordable, simple email marketing platform built for content creators and small businesses. It covers email campaigns, welcome and drip automations, contact management, signup forms, hosted landing pages (smart pages), RSS-to-email, and paid newsletters — with a free plan and low-cost paid tiers. SendFox also offers a transactional email API for developers (receipts, login codes, password resets, notifications), included on every plan, with a Resend-compatible endpoint. SendFox is made by AppSumo.

SendFox is designed for creators who want to grow and email an audience without enterprise complexity or per-subscriber pricing surprises: authors, YouTubers, podcasters, bloggers, and small online businesses. Emails are intentionally simple and text-forward, which keeps them fast to write and friendly to deliverability.

Key facts:

- Free plan available; paid tiers add higher contact limits and advanced features. Current plans and prices: https://sendfox.com/pricing
- Core features: unlimited email campaigns, scheduled sends, email automations (welcome sequences, drips), contact lists and tags, signup forms, hosted smart pages, RSS-to-email, referral campaigns, and paid newsletters via Stripe.
- An AI writer can draft campaigns from a link (a post, video, or article) or an idea, matched to the sender's voice.
- 30+ native integrations plus a public REST API and Zapier support.
- SendFox also provides an MCP (Model Context Protocol) server, so AI assistants can manage campaigns and contacts and send transactional email directly.
- Transactional email API: an HTTPS JSON API for one-to-one app email, available on every plan including free. It accepts Resend's API format, so a Resend integration switches by changing two environment variables. Emails count toward the plan's sends, the same as campaigns; there is no separate limit.
