You can use the APEX_MAIL package to send an email from an Oracle Application Express application. This package is built on top of the Oracle supplied UTL_SMTP package. Because of this dependence, the UTL_SMTP package must be installed and functioning to use APEX_MAIL.

APEX_MAIL contains three notable procedures. Use APEX_MAIL.SEND to send an outbound email message from your application. Use APEX_MAIL.PUSH_QUEUE to deliver mail messages stored in APEX_MAIL_QUEUE. Use APEX_MAIL.ADD_ATTACHMENT to send an outbound email message from your application as an attachment.

Oracle Application Express installs the database job ORACLE_APEX_MAIL_QUEUE, which periodically sends all mail messages stored in the active mail queue.


The APEX_MAIL package may be used from outside the context of an Application Express application (such as from a Database Scheduler job) as long as the database user making the call is mapped to an Application Express workspace. If the database user is mapped to multiple workspaces, you must first call APEX_UTIL.SET_WORKSPACE or APEX_UTIL.SET_SECURITY_GROUP_ID as in the following examples. The APEX_MAIL package cannot be used by database users that are not mapped to any workspace unless they have been granted the role APEX_ADMINISTRATOR_ROLE.

- Example 1
apex_util.set_workspace(p_workspace => 'MY_WORKSPACE');

-- Example 2
for c1 in (
   select workspace_id
     from apex_applications
    where application_id = 100 )
   apex_util.set_security_group_id(p_security_group_id => c1.workspace_id);
end loop;
