Using newer TLDs like .clinic or .vet for email sending domains presents several challenges. Experts, marketers, and documentation collectively suggest that these TLDs often face lower sender reputations, are perceived as spammy by both users and filters, and are subjected to stricter filtering by ISPs and blocklist providers. This can lead to lower deliverability rates, negatively impact brand perception, and increase spam complaints. Building a positive reputation, implementing strong email authentication, properly warming up domains, closely monitoring engagement metrics, and adhering to best practices are crucial to mitigate these risks.

Using newer TLDs (like .clinic or .vet) for email sending domains carries several risks related to deliverability and reputation. These domains are often perceived as spammy, which can lead to lower engagement, increased spam complaints, and stricter filtering by ISPs. Their lower sender reputations compared to established TLDs can result in more aggressive filtering and reduced inbox placement. This negative perception can also affect brand trustworthiness. Strong email authentication (SPF, DKIM, DMARC), proper domain warm-up, and diligent monitoring of engagement metrics are crucial for mitigating these risks.
