Here are some best practices to consider when implementing retry logic in your email marketing:
Set appropriate retry intervals: Start with shorter intervals and progressively increase the time between retries. Monitor delivery failures: Keep track of why emails are failing and adjust your retry logic accordingly. Optimize email content: Ensure that your emails are not triggering spam filters, as this can lead to delivery failures. Validate email addresses: Regularly clean and update your email list to remove invalid or outdated addresses.
