CiviCRM (Drupal 7) Problem sending bulk emails
Sending bulk emails depend on execution of scheduled jobs present at civicrm/admin/job?reset=1 URL path OR Administer -&gt; System Settings -&gt; Scheduled Jobs navigation menu.

The name of the job is Send Scheduled Mailings. Pls check if this job is enabled and running on your site.

Also, check the status of the bulk mail you created via civimail.




If the status is scheduled - the mailing is awaiting the execution of the scheduled job.
If it is "Completed" - the mailing is sent to the recipients.
