Sending timely targeted email notifications is crucial for engaging your audience with your product. To achieve this, you can use the Courier notification platform to schedule and send emails at the right time. Courier offers a low-code solution using its UI, which allows non-developers to create automation templates without needing extensive coding knowledge. This approach simplifies sending scheduled or recurring emails by leveraging Courier's automations designer, eliminating the need for third-party libraries like Crunz or manual cron job setup. Alternatively, you can use Crunz to handle scheduling and integrate it with Courier's PHP SDK for more control over send logic, especially when adding multiple steps or chaining together different actions. By utilizing Courier's features, you can efficiently send scheduled or recurring emails without the complexity of traditional task scheduling in PHP.
