Guides to the outbound stack, for people who sell without a sales department.
19 long guides so far, on the tools a solo founder, freelancer or small agency uses to find prospects, reach their inbox and keep track of replies. Each one is put together from the vendors’ own pricing pages and help centers and the mailbox providers’ published rules. Prices carry the month they were checked, and every guide ends with its sources.
Research and experience are kept apart. When a tool has been tried first-hand, those notes sit in their own dated box and are never mixed into the researched text. The editorial policy explains the rest.
