Liligo relies on Sendinblue's Email API to send millions of custom price alerts in real time

The Liligo travel comparison website relies on Sendinblue to send out its price alerts in real time. Its robust and scalable Email API allowed Liligo's marketing team to quickly set up a large-scale program, closely followed by one for its newsletters. The startup was particularly pleased with the deliverability of its communications, the intuitive interface and the responsiveness of the French-speaking technical support team.

A robust yet simple email routing tool

Liligo is a travel comparison website. A subsidiary of the eDreams ODIGEO group since 2013, it makes it easier for users to plan their travel by comparing unlimited deals on flight, train and bus tickets, car hire and hotels from hundreds of partners.

No bookings can be made on the Liligo website; customers are redirected to the corresponding partner website once they have chosen their deal. It’s a free online search and connection service. Users do not have to create an account but can set up price change alerts based on their search criteria, which are then emailed to them as often as they choose.

Chief Marketing Office Guillaume Rostand and his colleague Anne Sauzède, who is responsible for CRM and marketing campaigns, talked to us about their experience as Sendinblue users, and in particular about the Email API that allows them to email millions of price alerts in real time.

Bulk emailing price alerts in real time

At Liligo, price alerts are fully customizable. Users can choose to receive their alerts by email every day, once a week or as soon as the price changes. These customized emails must be sent in real time to meet users’ needs and they represent more than 90% of the turnover generated by the CRM, making them an essential strategic marketing tool. Volumes can reach  250,000 emails per day. In addition, Anne Sauzède regularly sends newsletters to her 400,000 subscribers.

The marketing team initially worked with an American solution they shared with other companies in the eDreams ODIGEO group. Suddenly, they were no longer able to use the existing solution, and another platform had to be found very quickly that would allow them to route their hundreds of thousands of price alerts in real time: “We looked for a new tool that was practical, less technical and more accessible,” explains Guillaume Rostand.

He was already familiar with Sendinblue, so it was the natural choice. Sendinblue’s ability to respond very quickly to setting up the Email API was a critical factor in making that decision. The French solution expertise, particularly in terms of email deliverability in Europe, combined with French-speaking technical support, were enough to convince the Liligo team.

Fast deployment of the Email API and excellent deliverability

Faced with a real time constraint to be able to continue sending out its price alerts, Sendinblue’s rapid deployment of the Email API made all the difference. “What I remember is that it was done very quickly. We had a conference call with the technical team and they did the rest,” says Guillaume Rostand.

From an operational point of view, Liligo uses Sendinblue’s Email API as a custom email router for its price alerts. This means the team forwards the content of each message from their own systems to Sendinblue’s via the API, which then delivers it. The API is powerful enough to accept up to 120,000 emails per minute while maintaining excellent deliverability thanks to the expertise Sendinblue has developed in Europe in the last ten years, particularly in GDPR compliance.

In addition to her newsletters, Anne Sauzède manages the company’s promotional campaigns with its partners—also in Sendinblue. During the pandemic, she opted for an information-based strategy about the travel restrictions and then the reopenings, allowing her to keep her contact base engaged.

The granular tracking of send statistics for both price alerts and campaigns helps her monitor the smooth flow of emails in detail and immediately identify any concerns. If there are any issues, the Liligo team know they can count on the technical support and dedicated Customer Success Manager they receive as part of Sendinblue’s Enterprise package. “The technical support in French is very responsive and there are no intermediaries involved. With our previous supplier, it took weeks to receive a reply,” Guillaume Rostand points out.

An intuitive interface and technical support that makes all the difference

Anne Sauzède confirms her satisfaction with the handling and day-to-day use of the Sendinblue platform. “The interface is very nice, the drag & drop method is really easy and the statistics immediately show you if there’s a problem.” She also underlines the excellent deliverability of the alerts sent through the Email API.

For the Liligo team, having a dedicated Customer Success Manager has made a real difference from both a technical and strategic point of view. Personalized support from an expert in the field enabled them to set up a new automation scenario and work on the deliverability of their campaigns.

With the platform’s solid foundations well established at Liligo, the team are now thinking about how to further refine their strategy; for example, by segmenting their emails by departure city or creating other campaigns based on this type of attribute.
