Never use Masonic titles when sending mail
Each Masonic lodge has its own secretary and its own Treasurer and these members have their own set of rules by which they must abide. Each has to abide by the regulations set by the Information Commissioner’s Office (ICO) and General Data Protection Regulation (GDPR) guidelines.
As well at that, “On no account should a Masonic rank be included with the name and address on an envelope being sent through the mail.”
