Case Study: Diamond Resorts achieves 25% faster email deployments and 98% deliverability with Twilio SendGrid

Diamond resorts uplevels its email marketing program with twilio sendgrid's marketing campaigns

Diamond Resorts, a membership-based hospitality company, relied heavily on email to attract and nurture members but found its legacy email provider cumbersome, inflexible, and poorly integrated with its marketing stack. The team needed an easy-to-use platform that enabled personalization, better deliverability insights, and faster campaign execution.

They migrated to Twilio SendGrid’s Marketing Campaigns, leveraging the Contacts API and Automation to integrate data, segment audiences, and program multi-touch journeys. The switch cut campaign setup and deployment time by 25%, improved email delivery to 98%, supported sending volume up to 3.5 million emails per month, and produced open rates as high as 70%, while giving the team real-time deliverability visibility and more effective personalization.
