It automatically scales up or down based on demand, ensuring that your emails are delivered promptly and reliably.

It employs various mechanisms to minimize the risk of emails being marked as spam and provides you with the necessary tools to monitor and improve deliverability rates. Additionally, AWS has established relationships with major ISPs (Internet Service Providers), which helps to reduce the chances of your emails being marked as spam or blocked. Amazon SES employs advanced email deliverability techniques, such as content filtering, IP reputation management, and bounce and complaint feedback loops, to increase the chances of your emails reaching the recipients’ inboxes instead of being marked as spam.
