Frequently asked questions about our email platform

How does the Send Time Optimization feature work?
When you send messages via our Email API or SMTP with Send Time Optimization enabled, our machine learning algorithm analyzes open and click data for each recipient to see when they are most active in their inbox. Emails are then suitably scheduled in the pipeline to be delivered at the right time.

Can I personalize emails with Sinch Email API?
Absolutely! You can personalize emails by conditionally displaying content based on contact properties and custom variables. Non-technical users can manage content, design, and personalization, while developers can focus on the integration with your system and data.
