I have a family website, private, requires a WordPress account, in WordPress. Some of my family members would like to get the option for notifications of new posts by email or text message.
Email seems easy enough, there are plugins and services for that.
But I'm concerned about text messages because we are geographically spread out, and I would like the option to queue the messages so that they are sent to users only within hours they choose.
External services or services based off RSS are not a great fit because the RSS feeds are not public and I'd like to keep it that way.
Is there a plugin suited to these specific requirements?
