At a minimum, how many outreach emails must you customize before switching to a template?

You should customize at least two outreach emails before using a template to ensure your approach is effective. The first email should be a highly personalized message to a key contact, allowing you to gauge their reaction and refine your core message. The second email should be a slightly less personalized version sent to another contact, helping you identify which elements resonate most and which can be templated. This iterative process allows you to test and optimize your messaging, ensuring that when you do switch to a template, it’s based on proven engagement rather than assumptions. Sending no customized emails (option "None") risks using an ineffective template from the start. Customizing "All the options" is inefficient and defeats the purpose of eventually using templates. Customizing three emails is also a valid approach, but two is the minimum to establish a baseline for templating.
