Great plugin, thank you

Great plugin, thank you
Positive Experience – more robust test email format is needed
by wavecrest·10 months ago·1 reply
I’ve had a very positive experience with this plugin—it’s the only one that worked reliably for my setup, which I truly appreciate. The core functionality is solid and performs as expected. One area for improvement would be the testing feature: while the plugin itself was already working perfectly, the test email was so minimal in content that my mail server rejected it. It would be great if future updates could include a more robust test email format to avoid this issue. Overall, thank you for a very helpful and functional tool!
