Domain Authentication

Set up SPF, DKIM, and DMARC so your emails actually reach the inbox.

When to use this skill

• Setting up email sending for a new domain
• Emails are landing in spam or being rejected
• Adding a new email provider or SaaS tool that sends on your behalf
• Preparing for Google/Yahoo/Microsoft bulk sender requirements
• Auditing an existing domain's authentication setup
• Locking down a domain that doesn't send email
