Promo and launch emails are the load-bearing column of any product or campaign launch. The templates here cover the full launch arc: pre-tease, day-of, final call, post-launch objection-handler. Plus seasonal: Black Friday counter-positioning, drops, bundles, and the 'we'll go quiet' close that earns the right to launch again next time.
The mistakes that hurt: faking scarcity, extending 'last day' deadlines, sending the same email twice in 24 hours. The wins: real numbers (32 seats, sold out in 31 hours last time), real deadlines, and a clear 'not for you' description that pre-qualifies the audience and reduces refund rates.
