currently, core_email_queue_send_all cron expression is */1 * * * *

I want to change to */5 * * * *

How can I change the time?


Create your own extension, make it depend on Mage_Core and add this to your config.xml:

<?xml version="1.0"?>
    <!-- ... rest of your configuration ... -->
                <schedule><cron_expr>*/5 * * * *</cron_expr></schedule>

This way you avoid changing core files which is a no-go.

In case you wonder how to make your extension depending on another: here is an example for a fictive extension Mzeis_Test (code goes into app/etc/modules/Mzeis_Test.xml):

<?xml version="1.0"?>
                <Mage_Core />

Take a look at Sending Emails by Queue in Magento 1.9.1

Email cron setting is defined in


     <schedule><cron_expr>*/1 * * * *</cron_expr></schedule>
  • do not suggest users to change code in the core ;) – Jeroen Mar 2 '15 at 7:48
