[SOLVED] Email All Customers OpenCart Admin

Im having problems with the mail application in the admin panel. When i select all customer it seems that only the first 20 customers actually receive emails. Does anyone know what might be causing this? Ive been messing with this for over 3 hours and cant figure it out, and my client is freaking out because this does not work.

Mailservers often have requirements to establish bulk mailing, mailing lists, or similarly denominated means of sending to more than even as few as four recipients at once. When those are in effect, they are enforced. They are intended to combat outbound spam, whether from shared or unshared host accounts. They provide one among means to prevent outbound mail from being filtered outbound or inbound (when it gets there) as spam and set aside.

Look in your control panel under Mail for such wordings as, "Please make sure that all the email recipients are subscribed to a certain mailing list before you send a mass mail."

If you have a roster of recipients that changes, or that lists more recipients than your host intends to accommodate at once, then you may need to avail yourself of a mass-mailing service or other solution, or of installable software that your host may even have already available. You may or may not be permitted to install on the host your own mailserver software (technically one server module per protocol of several), and on a shared host probably not.

You can ask your host's support for the host's preferences as to how you should dispatch such mail, and its advice as to your alternative means of dispatching it.
