Set up your email domain
Proper sender domain configuration so your emails actually reach inboxes.
Emails that don't land in spam
Transactional emails from a generic domain get flagged. Password resets, welcome emails, payment confirmations. If your domain isn't properly configured, they end up in spam folders and your users think your product is broken.
Inside Claude Code, type /domain. It walks you through sender domain configuration and audits your existing email templates. DNS records, authentication protocols, and template review in one pass.
What it covers
Domain verification with your email provider. SPF, DKIM, and DMARC records configured correctly. A review of your existing email templates for deliverability issues like missing unsubscribe links, image-heavy layouts, or content patterns that trigger spam filters.
The system tells you exactly what DNS records to add and where, then verifies they've propagated correctly.
