Not functioning with WP Offload Amazon SES plugin

Hi there,

I love the plugin and it has been working great. But it’s not working now with the WP Offload SES plugin that ties in with Amazon SES (simple email services). Whenever Woo Coupon Box tries to send an email there’s a delivery failure. All other emails sent through the site send fine, except those attempted by Woo Coupon Box.

The log shows this problem:
