Hi,
In case you are using the Acymailing Sending Service as sending methout, please note that our developers are aware of the problem. The issue is spread globally through the Amazon SES platform, which our sending service is using in the background. The developers are working on a problem with Amazon support and once they fix it, you will be able to send your emails.
In case you are using a different sending method, I kindly request that you submit a support ticket through our website at https://www.acymailing.com/support/. This will enable our team to efficiently and effectively provide you with the assistance you need.
