I'm tempted to write back.
Dear %%LAME_MARKETING_MANAGER%%,
While I always enjoy a good cup of %%BEVERAGE_BRAND%%, your email campaign has left me somwhat less than enthusiastic.
Are you sure %%FEATURED_SPEAKER_ONE%% and %%FEATURED_SPEAKER_TWO%% will actually show up? After all, they may be using a better %%MAIL_MERGE_PROGRAM%% than you (it could hardly be worse), and may have a different %%EVENT_DATE%% in mind.
Anyway, thanks for the %%GIFT_CARD_TYPE%% offer, and good luck to the first %%WINNER_COUNT%% people. I hope they actually get some beneift.
Sincerely,
%%FIRST_NAME%% %%LAST_NAME%%
