I have a problem with email campaigns.
Logically, when an email to which the campaign is sent may have security restrictions, they are usually corporate email accounts or domains.
When the mail is sent to Gmail, Hotmail, etc, and the mail falls in the main tray, the photos and other components of the email are loaded.
But, when it is private domain, no.
I have seen in some cases you can add a paragraph and a link similar to: If you cannot see the message in your inbox Click Here to view it on the WEB.
How can I redirect the client to a XXX URL to see the same mail I am sending but in the browser?
