Hi Helena, thank you for raising this, we can see how frustrating it is when you’re trying to resolve a blocked sending issue and can’t get through via email or phone. Let’s work through this directly so we can get you unblocked. If your emails are being blocked, it’s usually linked to one of the following: 

•  The sending server has been flagged temporarily due to spam/security rules 
•  The email address or domain is triggering filtering rules on the receiving side 
•  Authentication (SPF/DKIM) mismatch on the sending account 

To move this forward without escalation, please try the following: First, test sending a simple email (no links or attachments) to a different external address (like Gmail) to see if the block is general or only affecting specific recipients. Then, if you’re using a mail client (Outlook, phone mail app, etc.), try sending directly via webmail instead — this helps confirm whether the issue is device-related or account-level. Also, check if there are any bounce-back messages in your inbox — these usually contain a specific error code that will tell us exactly why the message is being blocked. Once we have that detail, we can guide you precisely on the fix without needing a long escalation process. Kind regards,
 The Mweb Team
