We advise you not to forward campaigns through your email client.

Forwarding a campaign sent through Rule means that it can be affected by the email client's settings and how it perceives and chooses to display the campaign's code with structure, images, etc. How forwarded campaigns are affected is controlled by external programs like Outlook, Gmail, etc. and does not originate from your template in Rule. This may result in the forwarded campaign having a different appearance.

Are you experiencing any of the problems described above? Try sending the campaign live to yourself (or through preview) or to a colleague.
