A: Hello,

Thanks for asking.

Can I know if yaymail pro and all addons working with multisite properly like wp ultimo and frontend admin dashboard plugins?
=> YayMail and addons work in WordPress admin backend. Multisite is supported.

Is white label?
=> No

If I am biilding multisite network can I use my lifetime license? Can I activate the plugin in all subsites once?
=> Yes, you can.

Do you have license manager so I can control my clients by sub license to avoid losing my general license?
=> No. It's one key for all sites.

Hope my answer helps.

Thank you.

Kelly
