Case Study: Realtor.com achieves stronger email deliverability with Twilio

Realtor.com optimizes email program with Expert Services

Realtor.com, the leading online destination for homebuyers, sellers, and renters, relied on Twilio SendGrid and Twilio Professional Services to support its growing transactional email program. As deliverability became more complex, the team faced domain blocks and bounce-rate issues that were putting email performance and lead-routing reliability at risk.

Twilio helped Realtor.com investigate the account data, identify high hard-bounce rates and a 10% block rate on an inactive lead-routing domain, and improve list hygiene and sending strategy. As a result, domain blocks were lifted, bounce rates were cut in half for the top email service providers, and overall delivery rates rose to over 99% for sending accounts, restoring confidence in the email program.
