You can now send email directly from your RDS for Oracle databases by using the UTL_MAIL package. To enable UTL_Mail for your DB instance, you need to create a new option group, or copy or modify an existing option group and add the option Oracle UTL_MAIL to it. You then need to associate this option group to your DB instance either by selecting the option while creating a new instance or while modifying an existing instance. Right now, we only support single attachments up to 32KB in size and only ASCII and EBCDIC character encodings. Amazon RDS supports UTL_MAIL for the Oracle version 184.108.40.206.v5 and later, 220.127.116.11.v6 and later and 18.104.22.168.v9 and later. These versions include the July 2016 Oracle Patch Set Updates (PSU).
