Well, you could.
But to be frank, the system is not designed for that. LeadCooker is built not for one-to-many marketing communication and broadcasting, but for one-to-one, precisely targeted communication with sales prospects, which implies a good deal of manual follow-up and individual work with every one of them. Prospecting emails are usually much more personal and should not be 'salesey' to be really efficient. That is because when you're prospecting for business, your goal is not to promote your product and/or service, but to get a genuine feedback from a real, individual prospect. Not quite a marketing goal, right?
Moreover, you risk getting banned if your emails look suspicious for email servers because of too much marketing tech inside them. For you not to be tempted, we did not include any of the common marketing tools and sophisticated formatting options in our template editor.
