Mailchannels blocking 
I ahve now been struggle with my newsletters since September 2019 last year, from they moved to Mailchannels. For more than 15 years I never had any issue with my newsletters going out to my clients. All you get to talk to is the call centre. Managers is just absent, and if you do not get any response on your tickets for more than 5 days, it is disgusting. My business is suffereing from this American Comany Mailchannels who blocks our ligitimate emails in SA. I am not on any blacklist, untill Mailchannels block my newsletter mail sending out, then the whole newsletter batch get blocked and then my email address is blocked by only two other blacklist companies. Always the same two.

I have now again lost the whole of January, that I cannot communicate with my clients due to 1-grid and mailchannels
