If you enable 'Blockchain Verification' for your campaign, omniMarketer will track campaign message clicks and when it was opened on the blockchain.
When contact opens a message or clicks on the link, a new contact note is created, in addition to blockchain record.
Navigate to 'omniMarketer \ Campaigns' and select 'Notes' from options dropdown next to the campaign.
Use options dropdown next the note to explore more details: customer and user it belongs to, campaign and message it is initiated with.
To view blockchain record, click 'Blockchain verification' link next to the campaign subject on the note.
