We'll create fresh WordPress site with Update customer installed. You have 20 minutes to test the plugin after that site we'll be deleted.
Useful plugin for dev freelancers that have disabled automated core updates to the websites of their customers, but need to inform them automatically, when maintenance is being carried out.
WordPress sends email to admin anyway, when automated update is enabled but in most times developers have disabled this feature.
Your customer needs to know when you work for his website in order to pay for a maintenance contract.
You can add multiple recipients, add your subject, compose your message with a wysiwug editor and when a WordPress core update performed the email you composed will be sent to the recipients you entered.
