Treating every relationship with the same frequency is why keeping in touch feels impossible. Here's a tiered cadence that's realistic and doesn't read as scheduled.

The mistake isn't reaching out too little. It's trying to reach out to everyone at the same pace - which guarantees you'll either smother your weak ties or neglect your close ones.
When people resolve to keep in touch better, they usually pick a single rule - message someone every week, reach out to one person a day - and apply it across the board. It collapses within a month, and for a structural reason: relationships don't share a natural frequency. A weekly nudge is far too often for the colleague you met once at a conference and far too rare for your closest friend in a hard season. Force one pace on both and you'll smother the conference contact and under-serve the friend. The fix isn't more discipline; it's different cadences for different tiers.
A simple tiering covers almost everyone. Inner circle (a small handful - closest friends, family you're near, a partner): no fixed cadence, because gravity keeps these alive; a tool here is for the life events, not the nudge. Close ties (good friends you'd be sad to lose touch with): roughly monthly to quarterly. Weak ties (people you'd be glad to hear from but won't initiate with - old colleagues, conference contacts, friends-of-friends): yearly. Dormant (relationships you've consciously let rest): never - kept on file for context, not for contact. Most of your network is in the weak-tie band, and yearly is the right default there.
Most people get the bands backwards
The common error is setting tight cadences on weak ties (where they feel performative) and no cadence at all on close ties (where life events quietly slip by). Flip it: weak ties want a loose yearly rhythm, close ties want you watching for the moments that matter, not a monthly check-in clock.
The fear with any cadence is that scheduled contact reads as scheduled - that the receiver can smell the calendar reminder behind your message. The resolution is to separate the two jobs the cadence does. The cadence decides when a person resurfaces in your field of view; it never decides what you write. When a yearly nudge fires, you don't send a templated check-in - you look at what you logged last time, find the genuine thread, and reach out only if there's something real to say. If there isn't, the cadence was a prompt to think of them, nothing more. Warmth lives in the specifics you write, which the schedule never touches.
Tiers aren't permanent assignments; they're a snapshot of where a relationship sits right now. A close tie moves to weak as someone relocates and the rhythm naturally slows. A weak tie jumps to close when you start a project together. A dormant relationship reopens after a chance encounter. The model only works if you let people move between tiers freely, without it feeling like a demotion or a verdict. The cleanest sign a tier is wrong: someone keeps surfacing overdue and you keep skipping them. That's not a discipline failure - it's the cadence telling you they belong a tier looser. Move them and the guilt evaporates.
Holding four different cadences across dozens of people is exactly the kind of bookkeeping a brain does badly and a tool does well. Contact Book lets you set a cadence per person - monthly, quarterly, yearly, never - and the dashboard surfaces only who's actually overdue, so you never have to compute the schedule yourself. Moving someone between tiers is a single change. The tiers are yours to decide; the arithmetic of who's due this week is what the tool quietly carries, which is the difference between a model that sounds nice and one you actually keep using past February.
