I have set up AcyMailing for my client to create and send emails using the front end. However, there is no 'Spam Test' link at the final stage, as I see in the backend.
How can I enable this for my client?
I'm afraid you can't. This is only available in the backend.
A workaround is to manually send a test mail to https://www.mail-tester.com/ It offers you the same reporting.
Thanks. Would it be feasible/possible to include a link to this in the client area?
