List Building & Growth

A list is not a number, it is an asset with a maintenance cost. Every address on it either earns its place or degrades the deliverability of every send you make to the ones that do. That is the single idea this hub is built around, and it explains why sunsetting subscribers appears here alongside tactics for adding them.

The first pillar covers where subscribers come from. The middle three cover what you do with them once they arrive — how they are grouped, what happens automatically, and how the database is kept clean. The last covers the software, because the right tool for a 2,000-person list is rarely the right tool for a 200,000-person one.

Growth tactics are ordered roughly by how much they cost to run rather than by how impressive they sound. Content upgrades and referral loops keep working after you stop paying attention to them; giveaways and paid acquisition do not.
