Although it's tempting to forward on a Campaign straight from your mail client (i.e Outlook and Gmail) it can cause big rendering issues!
When you forward an email, the mail client will make changes to the HTML. This can include stripping out certain HTML elements, wrapping your email in a blockquote, or inserting additional classes to the code. These changes directly affect the look of the Campaign and so can distort images, duplicate buttons, delete buttons, break images and unlink sources.
You are also not going to have access to the correct statistics from a forwarded Campaign, as it will just pull up against the original recipient which will skew your reporting.
Instead, if a recipient clicks on a Forward to a Friend link/icon in a Campaign they receive, it will be tracked in the Campaign's reporting under the Interaction tab > Forwards. For security and privacy purposes, we do not track who they forwarded it to. If the individual they forwarded the Campaign to, clicks on the link to view the Campaign, these will be counted as a part of the total views statistic.
If a recipient clicks on Forward in their email program (e.g. Microsoft Outlook, Gmail, Yahoo, etc.), this is not directly tracked in reporting. However, in this case, additional views of that Campaign (whether by the original recipient or by those they forwarded to) will be counted as a part of the total views statistic.
To create a Forward to a Friend link you will need to highlight the text/icon you wish to use or place the cursor where you wish to add the Forward to a Friend link > select the link button > Click on the Other tab > Select Create Link to Forward to a Friend.
