Cold Email Sequence Generator

This generates complete cold email sequences with 5-14 emails depending on your campaign type, from fast-track one-weekers to long-play nurture sequences. Each email follows a specific framework (intro, value proof, different angle, social proof, resource share, direct ask, breakup), and you get A/B test subject lines, optimal send timing down to the day and hour, and personalization variables with examples for finding the data. The output includes an email flow table with expected open rates and fully written email bodies with customization instructions. Honestly most useful if you're actually doing outbound at scale and need structure rather than just firing off one-off cold emails. The breakup email strategy on day 14 is solid, and the personalization levels let you choose between hyper-personal research or volume template mode.
