I have tried many plugins for subscribing to new comments, and this one is the best for the settings inside, the possibilities for messages, performance and convenience!
Many thanks to the developers!
please support the plugin, I am ready to show one’s gratitude you!
Thank you for this plugin. Very easy to configure and completely functional. Well Done Isabel and again, thank you. From France.
Thank you for making a nice plugin. ^^
This plugin is lightweight and very easy to use. However after using it for awhile I started to notice some items not working well.
1. The thank you email did not work at all but I did receive the test emails and I received an email when I did a test reply.
I noticed in the forum there has not been a response for about 10 months so not sure if this plugin offers support.
For us we had to uninstall this plugin because it did not fully work.
However I gave it 4 stars for the lightweight and simplicity. But with all the laws of GDPR and privacy policy etc. I think a more complex plugin would be appropriate for us.
Easy and useful!
Nice Plugin, although it may have problems with GDPR?
I still miss some features. But most I miss, that the author hasn’t answered for questions since more than a year. Well, it’s a free plugin, so I don’t wanna whine – but: what a pity.
Thanks anyway!
