Case Study: SendinBlue scales internationally and boosts agent availability with Aircall

Aircall + Zendesk help French startup scale internationally

Sendinblue, a French startup founded in 2012 to provide an SMB-focused, user-friendly marketing platform, needed to scale customer support as its user base grew. While they already used Zendesk, a rigid call-center system limited cross-team use and manageability, so they looked for a phone solution that would integrate seamlessly with Zendesk.

Adopting Aircall alongside Zendesk streamlined call handling, ticketing and voicemail routing, letting agents log follow-ups during or after calls. The integration raised agent availability from 25% to 75%, supported expansion to offices in France, the USA and India, delivered 22-hour weekday coverage, and enabled scalable multilingual support across 80 countries.
