The Guest List You Have Never Cleaned

The list has two thousand names. It has only ever grown.

Some of them came once, four years ago. Some are duplicates. Some are wrong. Nobody has removed a single entry, because removing feels like losing something.

What an uncleaned list does

It makes every rate look bad. ⚠️ Response measured against a denominator full of people who were never coming back — the campaign looks like it failed when it may have worked.

It hides the real number. How many actually-contactable regulars do you have? Nobody knows, and it is the more useful figure by a wide margin.

It costs money to send to. Directly, if you pay per contact.

It damages deliverability. ⚠️ Sending to dead addresses harms whether your messages reach the live ones — a technical cost with a very real effect.

It annoys people who asked to be left alone. The most serious item on the list.

What "cleaning" actually means

Not deleting history. Separating the list you contact from the record you keep.

⚠️ Guest history stays. Somebody who came twice in 2022 is part of your record and may return. That is different from being on the list you message on a Thursday.

The cleaning is about the sending list, not about forgetting anyone.

The four groups

Contactable and recent. Been in within a normal gap for them. The list that matters.

Contactable and lapsed. ⚠️ Worth one deliberate approach, not routine inclusion — and if that produces nothing, they move to the next group.

Not contactable. Bounced, invalid, unreachable. Remove from sending. Keep the history.

Asked not to be contacted. ⚠️ Remove immediately and permanently, and make sure the removal survives the next import — this is the one with consequences beyond marketing.

Doing it

Start with the bounces. ⚠️ Free, uncontroversial, and it improves delivery to everyone else.

Then the duplicates. Same person, two entries, split history. Merge, do not delete.

Then set a lapse rule. Not a fixed number of days — ⚠️ relative to their own pattern. A monthly guest at four months is lapsed; a twice-a-year guest at four months is not.

Then leave it. Quarterly is often enough, and doing it more produces nothing.

The number to produce afterwards

How many people could you actually reach tonight who would plausibly come?

⚠️ Most owners guess several times the real figure, and the real figure is the one that should inform every decision about promotion — because it is the audience that exists.

Three to hold

List size against contactable-and-recent. ⚠️ The gap is the finding, and it is usually large.

Bounce rate. Rising means the list is decaying faster than it is being maintained.

Opt-outs per send. ⚠️ A spike means you contacted people who did not expect to hear from you — which is what an uncleaned list guarantees eventually.

Where the record has to sit

Cleaning a sending list without losing guest history requires the two to be separable — the same record, with contactability as a property rather than as the reason the record exists. Otherwise every clean-up is a choice between accurate lists and remembering people.

tasteck keeps guest history on the guest record, so a guest can stop being on a sending list without stopping being a guest.

The list is not two thousand people. It is some number smaller than that, and not knowing which has made every decision about it a guess.
