The Challenge

Low delivery rates caused a dip in revenue and customer satisfaction.

IndiGo Car Hire sends 300,000 emails per month to over 100,000 customers worldwide to deliver sales promotions, reservation confirmations, modifications and cancellations, and to solicit customer feedback on their services and partners. As a broker, they rely on email to help earn new business and drive ongoing customer loyalty.

However, it was quickly becoming apparent that they had outgrown their current email system and needed a far more efficient way to deliver their emails. Low delivery rates were affecting their business, lowering revenue streams and hindering customer communication. They needed an easier, cost effective solution that wouldn’t tax their internal resources and could scale with them as they continued to grow.


Low cost impact and easy integration led to the prime solution.

IndiGo Car Hire decided to search for a cloud based solution to manage their email. Based on a recommendation, they decided to look at SendGrid. After researching SendGrid they found that its ease of use and low cost impact were unparalleled in the industry. These key factors made SendGrid the solution of choice of IndiGo Car Hire.


Improved delivery and response resulted in increased revenue.

After a quick integration and set up, they experienced immediate results. Delivery and response rates doubled with their first campaign, and as a result, business increased by 20% due to the improved customer communication that had been hampered by poor email deliverability.

Additionally, with access to SendGrid’s robust analytics, they could better tailor their email campaigns and utilize SendGrid’s 24/7 support team to help prevent, diagnose and troubleshoot delivery issues without taxing their resources.
