Not Permitted - TO DO ANYTHING!

Not Permitted - TO DO ANYTHING!

I recently set up Zoho CRM, and have added the IP addresses of my ipad4 and galaxy, but I am not being allowed to send an email to my clients, from computer, or devices. The devices seem to only have read permissions, I can't add a client, or email them. I have tried to work with the user permissions tabs but it is not making sense. I want to be able to do everything on each of my devices, can you help? I have made an email template and want to send it out urgently.
