Redis can significantly enhance the delivery of emails by managing queues and rate-limiting. Here's how:
Queue Management: Redis can handle multiple email queues, ensuring that emails are sent in an organized manner without overwhelming the email server. Rate Limiting: To avoid being flagged as spam, Redis can manage the rate at which emails are sent, ensuring compliance with email service provider limits. Retry Mechanism: Redis can store the status of each email and retry sending failed emails, increasing the overall delivery success rate.
