Campaign token does not resolved in mass email

[tanya]

Hello,
you don't have access to campaign details in email template.

There is a campaign record which name is "Campaign 2018', i have created a email template which content contains {Campaign.name} and sent mass email of the campaign using this template. however, the email shows {Campaign.name}, not "Campaign 2018'. Is there any tricks to resolve the campaign token in email?

Thanks.
