How Outdooractive delivers 3.5M highly-personalized “For You” emails a week with Sinch Mailjet

With over 60 million users, more than 1.1 million tours on their platform and a B2B network with 8,500 partner, Outdooractive is Europe’s largest platform for outdoor enthusiasts looking for their next adventure.  

With email volume driven by community updates, automated system messages, and B2B campaigns of more than 300 Million emails per year, Outdooractive needs a setup that sends reliably and personally at scale. The team has to deliver consistent, compliant, and targeted content — while keeping workflows efficient and transparent across multiple internal stakeholders. 

Their previous solution wasn’t flexible enough to manage different email types efficiently, and it wasn’t easy to use. Outdooractive wanted a setup that was efficient, scalable, transparent, and intuitive.  

With Sinch Mailjet, the team found the right solution to deliver different types of emails with a cohesive, branded look at scale. Mailjet’s intuitive email editor lets them create branded email templates and reusable components to maintain consistency across the organization, and the Mailjet API automatically syncs user data and newsletter sign-ups directly in the platform.  

“Sinch Mailjet combines technical control via API with efficient work in the email editor,” said Pirmin Mösle, CTO of Outdooractive. “This exact balance is what makes us successful.” 

They’ve also streamlined approval processes, thanks to integrated commenting and collaboration tools. Their team saves time and avoids friction, even when multiple departments are involved.   

Every week, Outdooractive sends a ‘For You’ email based on their interests and preferred language. Mailjet’s advanced segmentation lets them precisely target groups’ profile data, language, and user behavior.  

Dynamic content blocks automatically display the right content, while automated campaign workflows ensure each recipient gets the most relevant email at the right time — all while maintaining a consistent brand image in millions of inboxes. 

To make the most of these campaigns, Outdooractive focuses on clean recipient lists, low spam rates, and high deliverability. They use Mailjet’s features like automated list cleaning, deliverability analysis, and targeted exclusion that leave out inactive contacts, so the right content always gets to the right reader. 

When they need help, whether it’s about API questions, template setup, or deliverability, their personal Technical Account Manager – Mailjet Email Deliverability Services – provides direct assistance. 

Pirmin explained, “With Sinch Mailjet, it’s not just the technical setup that’s right for us, but also the consulting and support. Our personal Technical Account Manager helps us keep our deliverability rates consistently above 96%.” 

Now, Outdooractive can create a scalable email infrastructure that reliably covers both mass campaigns and targeted communications for specific groups and applications. Plus, Mailjet allows them to create, target, and deliver email campaigns faster and more securely. 

On the design side, Mailjet makes it easy for non-technical teams to create content independently. Modular templates help them preserve their brand identity, and the API connection automatically syncs data to reduce manual work. 

Built-in collaboration tools improve teamwork, while regular list maintenance keeps deliverability above 96% — much higher than the average rate of 83.1% reported by Emailtooltester.  

Their spam rate also stays under 0.01%, and their open rates are consistently high. Thanks to Mailjet, Outdooractive significantly surpasses industry standards, without overwhelming their teams with new work, no matter how much they grow. 

“Mailjet is a powerful email solution within the Sinch Communication Cloud,” Pirmin said. “The wider Sinch portfolio gives us a scalable foundation to manage every customer communication use case — all from one trusted partner.”
