9,000 emails per month, full Spark dashboard access, MCP server, and the complete REST API. No credit card required.

Yes. Include up to 10 attachments per email, 5 MB per file (10 MB total), as base64-encoded JSON. PDFs, images, Office documents, CSVs, and calendar files are supported.

Every Spark campaign email includes a one-click unsubscribe link automatically. Unsubscribed addresses are suppressed immediately and permanently, with a full audit trail. RFC 8058 one-click headers meet Google and Yahoo bulk-sender requirements.

Yes. The Brixus365 MCP server exposes 16 tools — send and batch-send transactional email, schedule and cancel sends, check delivery status and analytics, list and preview starter templates, and manage marketing campaigns — to Claude Desktop, Claude Code, Cursor, and any MCP-compatible assistant. Connect in one line with the hosted server (OAuth, no API key required), or self-host it from source — the server is open source.

Add your domain in Settings → Email Setup, publish three DNS records (SPF, DKIM, and DMARC), and verification typically completes in minutes. Authenticated domains improve inbox placement.

Brixus365 handles unsubscribe enforcement, suppression, audit trails, and data deletion automatically as your data processor. You handle consent collection and your privacy policy as the data controller. A DPA is available for paid accounts.

Hard bounces and spam complaints suppress the recipient automatically and permanently across the platform. Soft bounces are logged but not suppressed. Account health is monitored against a 90-day rolling window with warning and suspension thresholds.
