1. Cadence is a promise, not a preference
When a person hands over an email address, they are extending trust in a measurable amount. A published cadence turns that trust into something checkable. They can tell, within a week, whether you kept your word.
The Convergence Q45 sequences are built this way. Every message is scheduled before the first one sends, so the rhythm is a commitment rather than an accident of whoever felt inspired on a Tuesday.
2. Give the recipient the dial
One list rarely holds one appetite. A library director wants the essentials and nothing else. A reader in the middle of the forty five waypoints wants every prompt.
Four settings cover nearly everyone: everything, standard, minimal, and none. Minimal should still carry the welcome and the decision message, because those two are the ones people later say they wish they had seen.
3. Pause is the most pastoral button on the page
Life interrupts. A death in the family, a hospital admission, a season of grief. In those weeks a well-meaning sequence becomes noise.
A pause holds the queue without deleting it. When the person resumes, the same messages release in the same order, and nothing was lost. Unsubscribing should always remain available, but pause is the door people actually want.
4. Consent is checked at send, not at signup
The only safe design re-checks permission at the moment of sending, not at the moment of enrollment. A person who opted out on Monday must not receive a message queued on Sunday.
Every scheduled message in this mission passes through one consent checkpoint. If permission changed, the message is blocked and the reason is recorded.
5. Measure the touch, not just the total
Open rates flatter. What matters is which specific message moved someone to a next step: booking a session, downloading a bookplate, joining the field year list.
Attribute each next step click to the message that carried the link, then compare by demographic. You will usually find one or two touches doing most of the work and several that can be retired.
