Email Beautifier can only catch those emails that use Joomla's Native Email Class for sending emails. This is the case with most Joomla Extensions so most of your emails will be beautified. Some extensions like Community Builder are known to use their own Library. So emails generated by such extensions cannot be beautified.
*Note: Email beautifier component just wraps the saved Email Beautifier template to the outgoing emails only. A component doesn't modify the outgoing mail content.
I Use Joomailer MailChimp integration. Are my emails not getting Beautified?
Joomailer uses a Plugin for giving the ability to use Amazon's STS Email service for transactional emails. If you are using this plugin & want to use the transactional mail service, a little coding is needed to be done in the STS plugin so that EB works. If you face this issue, let us know & we shall help you fix this. We shall be working with the Joomailer team so that this is resolved permanently soon.
Email beautifier applies the template based on URL parameter like option, view, layout, task.
Depending on your different URL parameters, you can create different Email Beautifier templates. While sending email, Email Beautifier compares current URL parameters and saved template's conditions, and the matched template will be used while sending the mail.

Email beautifier applies the best template based on URL parameter like option, view, layout, task.
Only these parameter will be considered while applying the template. So you have to use CronJob functionality for JOMSOCIAL instead of using the system plugin.
To disable sending email from the system plugin - GOTO-> Jomsocial-> configuration -> "site section" : Under this search for - "Cronjobs / Scheduled Task Process" subsection and Set "Send email on page load" to NO.
I want to use Email Beautifier just for one component. When I only make one template and assign that one to the particular component, will the other mail templates for all the other components remain untouched?
Yes, Email Beautifier can work that way. Create a new template but do not set it as default and set it only for one component.
