Unified provides functionality that all WordPress sites use or should use, such as page caching, email configuration, email logging, clean responses, custom SMTP and good security.
The ultimate vision for Unified is for it to be the standard plugin you have on all your sites, providing important functionality, that is not a part of WordPress core.
Setup your custom SMTP for the site to use, to make sure email is sent by proper account, with high deliverability. Emails that never reach their destination can cause all kinds of problems.
Usage example: E-commerce sites or sites sending emails where deliverability is important, which is the case for most sites.
Queue email instead of making the user wait until it is sent. The emails will then be sent in the background and if there is some problem, it will just be sent when it is possible.
Usage example: When as example E-commerce sites order emails, which forces the user to wait until it is sent.
Log all the emails going out of your sites, so you can see what was sent and what the content was. Very useful when figuring out which emails was sent from your site to a specific user or search for content.
Usage example: Can be a order confirmation that is sent to a user, that you want to see how it looks and what it contained.
Page caching is a must have on any site, to massively increase speed of the site for users or customers, by only generating it once and serving it many times. Smooth for both users and server resources.
Usage example: Users/people are less likely to stay on a page if they experience a slow site, so by improving this, you can improve conversion rates on your site, no matter if it is e-commerce or generating leads.
All functionality in Unified has a core focus on performance and security, as this should be the core in all plugins. When you disable functionality, the code for that functionality is never loaded, so we always have the fastest possible site, both for users and administrators.
