Zoho blocked my account

My account omar@omnitrade.ca is now blocked from sending outgoing e-mails and I lost hours of work as my potential partners aren't in my time zone.

It's been two years I have been using Zoho mail services and never did this happen to me before. I am very upset and do not agree with Zoho's terms or definition of the e-mail sending policy because I am not trying to market or spam in a short period of time and Zoho says its mail service is to conversate for business purpose, well I need to send e-mail to new potential partners presenting myself before they decide to conversate with me and as I am looking to deal in few countries I do have to knock a few companies.

Please unblock my e-mail omar@omnitrade.ca and if not please let me know so I can export my mail boxes and switch for a new mail service provider.

Best regards,

Omar Faruque
