The company Spot switched its primary domain from spot.xyz to spotvirtual.com, resulting in improved email deliverability, website accessibility, and customer perception. The .xyz domain was found to be associated with spam and malicious activities, leading to issues with email and SMS deliverability. The company recommends choosing a top-level domain with caution, opting for tried and true extensions like .com, .org, and .net. This decision was based on anecdotal evidence and quantifiable data, including improved email open rates and meeting conversions.
