# Smart Sending {% embed url="" %} **What is Smart Sending?** Smart Sending is a feature that allows you to set a time limit (for example, 8 hours or 24 hours) within which a subscriber will not receive more than one email from you. This feature helps prevent your subscribers from receiving too many emails in a short period, ensuring you don’t overwhelm them with multiple emails. #### Why Is Smart Sending Important? Smart Sending helps you avoid sending too many emails to your subscribers in a short period. It ensures that they don’t feel overwhelmed or annoyed. By limiting email frequency, you improve engagement, reduce unsubscribes, and increase the chances of your emails being opened. \ \ This leads to a better experience for your customers and improves your email deliverability. In simple terms, Smart Sending helps you stay connected without overdoing it. **Activating Smart Sending:** 1. Go to your account name located at the bottom left corner of your screen. 2.
