WordPress plugin for sending out notifications by html email from the add/edit post/page/cpt screen.
Use a wysiwyg editor to write and send html emails to user groups from the add/edit post/page/cpt screen.
View all emails sent from the post/page/cpt directly from the add/edit post/page/cpt screen.
Choose the post types that you would like to see the send email wysiwyg editor and overview from.
Lets the users decide if they want to receive emails.
The plugin uses wp_mail() to send out mails so with the default settings there are limitations.
Some host providers has a limit for how many emails there can be sent out every hour. If the mail() function bugs, not all emails will be sent out. Sending out mails from servers on shared hosting has a tendency to end up in the spam folder in the users email client.
These limitations can be overcome by using a 3 party plugin that uses an external service to send out mails by hooking into wp_mail()
