Mailock sends read notifications to confirm your recipient has successfully read your message (and answered any challenge question) so completes the trail of your message.
As such they can’t be turned off, however by setting up some message rules you can filter them into their own folder giving you an audit trail if you ever need one.
The following details how to set up these rules in Outlook but there are similar options in Gmail and others.
In Outlook go to File > Info > Manage Rules & Alerts
Click on ‘New Rule’
Select ‘Move messages from someone to a folder’ and click on ‘Next >’
Tick the boxes next to ‘from people or public group’ (1), ‘where my name is in the To or Cc box’ (2) and ‘with specific words in the subject or body’ (3)
In the ‘Step 2’ box, at the bottom of the 'Rules Wizard' window, click on ‘people or public group’ to show the ‘Rule Address’ window. Type ‘email@example.com’ in the bottom field and click on ‘OK’
Still in the ‘Step 2’ box, click on ‘specific words’. In the ‘Search Text’ window type ‘has just been opened by’ then click on ‘Add’ followed by ‘OK’
In the same box, at the bottom, select ‘specified folder’. Once on the ‘Rules and Alerts’ window click on ‘New’ and name your new folder for the read receipts (this will create your new folder within your Inbox but it can be added to wherever suits you best)
Check your rule descriptions and click on ‘Next >’. If any aren’t correct just click on the one to change in the ‘Step 2’ box
Click on ‘Next >’ again on the exceptions window
Type a name for your rule, such as ‘Mailock Read Receipt’. Tick both ‘Run this rule now on messages already in “Inbox”‘ and ‘Turn on this rule’ and click on ‘Finish’
From this point any Mailock read notifications will be sent to your new folder instead of your inbox.
