Sendly

Sendly is an email platform for product teams: a transactional sending API, campaigns, visual workflow automations, contacts with custom fields, lists, dynamic segments, topic preferences, suppressions, sending-domain setup and analytics. The Sendly connector lets Claude run that workspace from your own account - look up contacts and segments, explain how last week's emails performed, draft a campaign or template, build a multi-step onboarding workflow from a brief, check why mail from a domain is not landing, validate addresses, manage suppressions and topics, and, only when you explicitly confirm, send. It serves Claude two tools, search_tools and execute_typescript, through which it reaches these operations.

This connector sends real email. Sending is treated as the dangerous action it is. Every connection goes through OAuth with per-scope consent: read scopes are pre-selected, sending and destructive scopes are unchecked behind a warning, and a tool whose scope you did not grant is never offered. Sending a campaign is two-step - the first call returns the audience size and asks, and only a second call carrying an explicit confirmation sends. Test sends reach only your own verified address. Mail leaves only from domains you have verified, and every project has daily and monthly sending caps tied to its trust tier.

The connector sells nothing in-chat, generates no images, video or audio, and serves no ads. Address validation and list cleaning are metered features of your Sendly plan. Works on every Sendly plan; usage rides your plan's normal sending limits.
