Hi,
The certificates are not sent to you via mail anymore, you need to download them and print them yourself or you can organise from the MCP website.
If you're having issues logging in to the MCP website (https://mcp.microsoft.com) after your MC ID has been sent to you via email, contact your Microsoft Regional Support Centre. The contact details are here:

You can also send them an email at MCHelp@microsoft.com
