Need assistance with MX record to use on my website

Hi.

MX records are usually not needed to the extent that your website is hosted in a custom domain.

MX records are typically used when setting up an email receiving server.
Amazon SES is mainly used as an outgoing mail server, but it can also be used as an incoming mail server.

Register the MX record as described above, receive the email, and process the email with Lambda etc. Please note that it is not intended to be received by a regular mail client.
