Important: guaranteed email delivery
Doctolib wanted to strengthen the reliability of their email delivery setup by adding Spotler SendPro as a second partner to manage their high-volume mailing. A major advantage of this dual setup is guaranteeing continuity if one provider experiences an outage or delivery issue.
Spotler SendPro’s platform is used for all forms of transactional email communication. This includes:
- Appointments: confirmation, reminder, reschedule and cancellation
- User account: One-Time Password and account creation confirmation
- All transactional emails regarding telehealth
- Messages shared via the app: document sharing, messaging, etc.
- All transactional emails regarding onboarding
- Finance: payment requests, invoices, etc.
Doctolib uses a light branding approach in its transactional emails. Only the basics, such as colour and logo, are clearly visible. The focus is on the legibility of the emails. The vast majority of emails are shared via the app or website.
