Toolbar Extras by default supports a lot of major WordPress Optin & Newsletter plugins and brings them to the Toolbar – most of them for the first time ever!
You find these plugins – if installed and activated – within the Site Group under the “forms hook place”, just below the “Media Library” item.
- MailChimp for WordPress
- OptinMonster API
- Convert Plus (was formerly known as ConvertPlug)
- Convert Pro, including Convert Pro Addon
- Bloom
- Hustle
More plugins in this area will be added over time. For example, I have plans to add support for Mailster and MailPoet (v3).
Note: For the related category of plugins – visual form builders – please see this appropiate support document.
