Deliverability

Reach the inbox consistently by combining domain authentication, list hygiene, and engagement-aware content.

Authentication

• Verify SPF, DKIM, and DMARC before production volume.
• Align From domain with DKIM signing domain (strict alignment for DMARC).
• Use a custom tracking domain so links match your brand.

List hygiene

• Validate addresses before import (Validate email).
• Honor suppressions automatically applied on bounce/complaint.
• Separate transactional and marketing streams (type field).

Content & engagement

• Always include a one-click unsubscribe for marketing.
• Avoid URL shorteners and misleading subject lines.
• Warm new domains gradually; don’t blast cold lists on day one.

Monitor

Watch bounce and complaint rates in the dashboard, subscribe to email.bounced / email.complained webhooks, and review Usage for volume spikes.
