API

A real API surface, not a token afterthought.

SendyKit turns Sendy into a scriptable platform: brands, lists, subscribers, campaigns, templates, analytics, billing, doctor, audit, and more.

Core data

Brands: CRUD, multi-brand, scoped queries
Lists: CRUD, custom fields, member counts
Subscribers: CRUD, suppression, import/export, lookup
Campaigns: drafts, scheduling, reports, bulk operations

Content + automation

Templates: CRUD, preview, GrapeJS integration
Segments, rules, autoresponders, and tags
Sequences: drip steps, enrollment, goals
Funnels, queue, tracking, and webhook surfaces

Operator systems

Settings, billing, doctor, audit, analytics
Admin shell + Sendy compatibility layer
Idempotency, auth policy, and rate-limit guardrails
Brand-aware workflows and extensible service layers

CLI

CLI-first for operators and agents.

Pipe-friendly JSON output, shell completion, and category coverage that mirrors the API.

Capabilities

The operator stack Sendy never shipped.

Analytics intelligence

Open rate, click rate, bounce rate, growth, engagement scoring, geography, client analytics, send-time optimization, and bot heuristics.

Health Doctor

68 checks across DNS, PHP, cron, database, SES quota, and SLOs, with scheduled runs and room for auto-fix workflows.

SMTP overlay

Use SendGrid, Brevo, Postmark, Elastic Email, or generic SMTP. Override per brand and fall back safely.

AI authoring

OpenAI, Anthropic, Google, Groq, xAI, and local providers for subject lines, full drafts, and A/B variants. BYOK where required.

Visual editor

GrapeJS drag-and-drop builder with template management, preview flow, and mobile-responsive output.

Audit trail

Every mutation logged with redaction, retention policy, purge worker support, and admin-visible traceability.

Compatibility

Built around Sendy. Not jammed into it.

No core modifications

SendyKit wraps around your licensed Sendy install on the real domain you already use. Surgical compatibility, not a fork-and-pray rewrite.

Bootstrap 2.3.2-aware admin overlay
Proxy-safe upgrades and shell patterns
Versioned migrations and auditability

One product, multiple operating models

Self-hosted keeps ownership. SaaS keeps operator convenience. Both preserve the same core surfaces: API, analytics, audit, doctor, editor, and automation.
