Several factors can impact the speed at which emails are sent and delivered:
Server performance: The capacity and speed of your email server can significantly affect how quickly emails are processed and sent. Email list size: Larger lists require more resources and time to process. Content complexity: Emails with heavy images, videos, or complex formatting can take longer to send. Throttling policies: Some email service providers (ESPs) have throttling limits to prevent spam, which can delay email delivery.
