Campaing on hold for more than a week

Campaing on hold for more than a week

As someone with an existing site, I use Brevo to send newsletters to my users. Decided to tryout Zoho only for my first campaign to be placed on hold. Tried reaching out to support, but no response. Zoho Campaigns claims that my domain is new and the number of users is many. Please, I would like anyone's help resolving this issue.
