Problem Temporarily suspended

Hello,

I’m having a problem with Mail Poet, which tells me that the MailPoet sending service has been temporarily suspended for your site due to a deterioration in e-mail deliverability.

I only send newsletters for events in my restaurant and I do not understand my Mail Poet account is activated, everything is green and I can not contact your support because I use the free formula and you have to pay to get help …

can you help me?

Thank you
