Welcome series = the cheapest revenue you will ever build

A 4-email welcome series typically delivers $5-$30 in lifetime revenue per subscriber. Build it once, run it forever, and it compounds with every new signup. Most ESPs (Klaviyo, Mailchimp, Sendlane) ship welcome flow templates that take a day to deploy.

How long should a welcome series be?
3-7 emails over 7-21 days is the standard. Stop when subsequent emails fail to outperform regular newsletter content.
