Sending

Send individual or scheduled messages with HTML, plain text, templates, attachments, custom headers, tags, and reply-to addresses through the HTTP API.

Contacts and campaigns

Contacts store subscriber data and custom properties. Segments group contacts, topics record subscription preferences, and broadcasts deliver a template to the selected recipients. Emailr tracks delivery events and suppresses recipients who should no longer receive mail.

Inboxes

An inbox gives your team a sending identity and a place to work with incoming conversations. Threads support replies, drafts, scheduling, labels, stars, spam, and trash. Inboxes can use signatures and can notify connected Slack channels.

Templates

Create reusable HTML and text templates with variables and preview them before sending. Templates can be used by transactional sends and broadcasts.

Webhooks and integrations

Webhooks deliver transactional, domain, and receiving events to your application. Emailr also supports inbound automation providers such as Zapier and n8n.

API and access

API keys can be scoped to the resources an integration needs. Use test keys outside production and live keys in production. See the generated API Reference for the current endpoints and request schemas.
