While the TLD itself might not be a primary factor, it can indirectly influence cold email deliverability. Domain age, sender reputation, email authentication (SPF, DKIM, DMARC), email content, bounce rate, and engagement are more critical. Newer or less common TLDs might face initial suspicion from ISPs and spam filters. Cold emailing, regardless of its purpose, can be considered spam if recipients haven't consented to be on the mailing list and violates the terms of service for most email providers.
