Mailercloud

At first, this was a new hope, a much better tool than, e.g. mailerlite. But then, suddenly, and I don't know for how long, it stopped working. Some emails got collected but mostly not. I tried it several afternoons to get it running again. The support doesn't react, the bot is worthless, documentation explains basics (that's necessary, of course) but nothing more.
The systems seems quite buggy. I get emails that tell me that mailercloud has received a submission, but the lists stay empty. Reloads doesn’t matter, waiting some days that the system can catch up, nothing better.
Unfortunately the time to give back is gone.
Maybe I write to Appsumo, I’ll buy no more deals, most of the tools just cost time because the software is not working as expected and the support is awkward.
I am sorry to make the general statement, but I am done.
Maybe the change my mind with a sensational reaction, but I am not expecting this.
Bye,
Rudolf
