Summary
While domain name choice alone might not directly trigger spam filters, a combination of factors, including the perceived intent and association with spam-related activities or brand impersonation, can significantly impact sender reputation and deliverability. Key to success is using clear, legitimate-looking domain names, avoiding misleading terminology or impersonations, and ensuring proper authentication (SPF, DKIM, DMARC) to build trust and avoid raising red flags. Domain reputation is a key indicator for spam filters, so careful selection is crucial.
Key findings
- Indirect Impact: Domain name choice indirectly impacts deliverability via sender reputation.
- Perception Matters: A domain name's perceived intent and legitimacy influence deliverability.
- Authentication Not Enough: Proper authentication is necessary but not sufficient to guarantee deliverability with a poor domain name.
- Brand Impersonation Risks: Mimicking established brands increases the risk of being flagged as phishing.
Key considerations
- Legitimate Look: Choose a domain name that appears legitimate and trustworthy.
- Avoid Spam Signals: Avoid spam-related keywords, excessive hyphens, and numbers in the domain name.
- Clear and Relevant: Use a clear and relevant domain name reflecting your brand.
- Authenticate Properly: Implement SPF, DKIM, and DMARC authentication protocols.
- Monitor Reputation: Monitor domain reputation using tools like Google Postmaster Tools.
