We have been users of ZOHO email for the last 3 years but for the past 2 weeks for some reason our emails are not being delivered to our clients with whom we previously never had any issues. We can receive their emails but they do not receive our email. We thought this was an isolated incident but this has happened with several of our clients in the past 2 weeks to the point its started affecting our business. We have 9 email accounts on Zoho and all of them have the same issue!
