I'm confused by the information presented in the application detail page of Zoho One. I'm a solopreneur with a single-seat Zoho One Enterprise license and I need to communicate externally .. extensively. The plan details page suggests channels are limited to 100 members. Whereas the pricing plan comparison page on the Cliq marketing site says 2500 for enterprise level. 

If it's 100... that's going to kill my use case as it is my understanding that external customers can only be communicated with using an external channel.

Please clarify so that I can analyze the ability of Cliq to facilitate my external user community.
