Email Drip Builder
A drip sequence is a contract with the user: they gave you their attention, and you will return it with value at the right moment. Sequences that read like mail merges get unsubscribes. Sequences timed to behavior build habits.
Anchor Email 1 on the First Value Moment
Email 1 sends immediately on signup and has one job: show the user the fastest path to the product's core value. No feature tour. No company history. One action, one link. Subject line states the outcome, not the product name.
Space Subsequent Emails Around Behavior Gaps
Emails 2 through 5 fire based on what the user has not done, not on a fixed timer. If the user completed the target action from Email 1, skip Email 2 and advance to the next milestone. Fixed-timer sequences waste sends on users who are already activated.
Each Email Earns the Next Open
Every email in the sequence must deliver something independently useful: a tip, a benchmark, a shortcut, a case study. If a user unsubscribes after reading Email 3, they should still have gotten value from the sequence. This reduces unsubscribe rates and builds sender trust.
Write Subject Lines as Promises, Not Headlines
A subject line is a promise about what is inside. Match the promise exactly. Bait-and-switch subjects boost open rates and tank click rates. The best subject lines are specific and slightly incomplete: the body finishes the thought.
Gate the Sequence on a Key Action
Define one milestone action that means the user is activated. Once they hit it, stop the onboarding drip immediately and move them to the engagement track. Sending onboarding emails to already-activated users erodes trust and skews engagement metrics.
Cap Sequence Length at Eight Emails
If a user has not activated after eight emails, a ninth will not fix it. Move them to a dormant segment and address them with a win-back campaign instead. Endless drips that never resolve create unsubscribe pressure across the entire list.
