Summary
Sending email from a newly registered domain is widely discouraged due to the lack of an established sending reputation and inherent risks of being flagged as spam. Experts and email marketers emphasize that new domains haven't built up trust with ISPs and recipient mail systems, making them more susceptible to spam filters and RBL listings. The presence of protections against practices like 'domain tasting' and 'fast flux spam' further restricts the viability of new domains for immediate mass mailing. A consistent recommendation is to warm up the domain and IP gradually, implementing proper email authentication and monitoring deliverability to build a positive reputation and avoid potential abuse.
Key findings
- Reputation Deficit: New domains lack an established sending reputation and trust with ISPs, leading to deliverability challenges.
- Spam Filter Triggers: Freshly registered domains are more likely to trigger spam filters and security tools due to the absence of a known history of legitimate activity.
- RBL Inclusion: New domains sending at volume are often listed on Real-time Blackhole Lists (RBLs), further hindering deliverability.
- Spam Activity Association: Newly registered domains are frequently used for spamming activities, leading to preemptive blocking and stricter scrutiny.
- Domain Tasting/Fast Flux Protections: Existing protections against practices like 'domain tasting' and 'fast flux spam' continue to impact new domains, restricting their use for immediate mass mailing.
Key considerations
- Implement a Gradual Warm-up: Gradually increase sending volume to build a positive sending reputation with ISPs, avoiding sudden spikes that trigger spam filters.
- Ensure Accurate DNS/RDNS: Configure accurate DNS and RDNS records for the domain to establish legitimacy and improve deliverability.
- Email Authentication Protocols: Implement proper email authentication protocols (SPF, DKIM, DMARC) to verify sender identity and enhance trust with ISPs.
- Monitor Deliverability Metrics: Continuously monitor email deliverability metrics, such as bounce rates and spam complaints, to identify and address potential issues early on.
- Adhere to Sending Best Practices: Follow established email sending best practices, including list hygiene, engaging content, and clear unsubscribe options, to maintain a positive sender reputation.
