Send transactional and marketing emails through pre-warmed IPs with authenticated domains. Track delivery, opens, and clicks across every message you send.
Email delivery
Send password resets, order confirmations, newsletters, and broadcast campaigns through pre-warmed IPs with established sender reputation. Build emails with React components or a visual editor, and enhance recipient tracking with conversations.
Capabilities
Pre-warmed IP pools with established sender reputation ensure emails reach inboxes. DKIM, SPF, and DMARC authentication configured automatically for your sending domain.
Send newsletters and marketing emails to recipient lists. Schedule sends for optimal timing and track campaign performance with detailed analytics.
Use Conjoin Messaging Conversations to group emails into threads. Link messages to contacts, orders, or campaigns for complete recipient history and reply tracking.
Build emails with a drag-and-drop editor that outputs clean HTML. Marketing teams can write, format, and style emails without touching code.
Build email templates with React components instead of table layouts. Write JSX, use Tailwind classes, and render to HTML when sending.
Store HTML templates with variable placeholders. Update email designs without code deployments by editing templates directly in the dashboard or via API.
Track when recipients open emails and which links they click. Engagement data flows back through webhooks or the tracking API.
Send from your own domain with automatic DNS configuration guidance. Maintain brand consistency while using Conjoin infrastructure.

Attach files up to 25MB per email. PDFs, images, and documents transmit securely with proper MIME type handling.
Hard bounces automatically suppress future sends to invalid addresses. Soft bounces retry with exponential backoff before marking as failed. Dynamic suppression lists keep you compliant with CAN-SPAM and GDPR.
Emails delivered to inbox, not spam
Time from API call to dispatch
Transactional and marketing combined
Why it matters
Send your first email in minutes. Configure your sending domain, verify DNS records, and call the send endpoint. Emails route through pre-warmed IPs with authentication headers applied automatically.
Create a welcome email template in React with styled components. When you need quick copy changes, update the text in the visual editor. Both approaches render to the same deliverable HTML.
Send a product update to your newsletter subscribers. Watch engagement metrics in the dashboard as recipients open and click. Enable conversations to capture replies and build recipient history over time.
A password reset email shows as delivered, opened after 2 minutes, and the reset link clicked 30 seconds later. Your support team sees this timeline when a user reports issues.
Built for Your Workflow
Send through pre-warmed IPs with established sender reputation. DKIM, SPF, and DMARC authentication headers apply automatically to every message, and deliverability metrics track inbox placement rates.
Reach inboxes consistently and reduce support tickets about missing password reset emails.
Send broadcast emails to recipient lists with the same API you use for transactional messages. Enable conversations for reply threading and per-recipient engagement history.
