We found suspicious traffic to our site and hence have ramped up DDoS mitigation. Due to this, there is a delay in e-mail reception.

Our infrastructure team has been constantly monitoring this with high priority and things are getting back to normal now. 

Please be assured that there will be no data loss.

We appreciate your patience on this. If you face any other issue, feel free to write back to us on support[at]zohomail[dot]com.
