Finding a conversation again: search, tags and tidying up

The conversation is your record, and it is worth as much as your ability to find things in it. A year in, a shared inbox holds everything customers told you — addresses, preferences, complaints, promises your team made — and none of it helps if the only way to reach it is scrolling.

Three tools, and each rewards a habit rather than a setting.

Search

The search box above the chat list filters your conversations as you type. It is the fastest route to a customer whose name or number you half-remember, and it is where most lookups should start.

Which makes one thing worth doing consistently: save contact names properly. A list full of raw phone numbers is a list you cannot search, and the effort of naming a contact is one second at the moment you first speak to them.

The cleanup that keeps tags honest

Tags decay. A customer tagged "interested in the sale" two years ago is not, and a list full of stale labels makes every audience you build from them slightly wrong.

There is an automatic cleanup for this, and it is worth understanding precisely before you turn it on, because it is blunt by design. It runs daily at 3:00 AM and it removes all of a contact's tags when both conditions are true:

They were tagged more than N days ago.
They have exchanged no messages in the last M days.

You set both numbers. Note "all" — it does not remove the stale tag and keep the others; a contact that meets the thresholds loses the lot. That is fine for the interest-and-campaign tags most stores use, and it is a reason not to record anything permanent as a tag.

What should never be only a tag

Opt-out status. Far too important to be swept up by a cleanup rule.
Anything permanent about the person — their city, their usual size, their company. Those are contact fields.
Anything you would be embarrassed to lose.

The test is simple: if a tag disappearing overnight would be a problem, it should not have been a tag.

Habits that make a year of history usable

Name contacts the first time you speak to them.
Save answers to fields, not to memory — a size, an address, a company name.
Write a note when something happened that the transcript does not show.
Set the conversation status so open means open.
Keep the tag list short and let the cleanup handle the rest.

None of those take more than a few seconds in the moment, and together they are the difference between a searchable record and a very long chat log. Steps three and four are covered in internal notes and mentions and open, pending, resolved.

Why this matters commercially

Beyond convenience, two things depend on it.

Your audiences. Every campaign you send later is built from tags and fields, so the accuracy of those is the accuracy of your targeting.

Your costs. A customer whose details you already have is a customer you do not need to ask again, which keeps conversations short — and short conversations answered inside the 24-hour window are free and unlimited under Meta's pricing documentation.

Frequently asked

Does the cleanup delete conversations?

No. It removes tags from inactive contacts. The conversations stay.

Can I run it once to see what happens?

There is a run-now option alongside the settings. Set generous thresholds the first time.

How far back does history go?

As far back as your account. What limits you is how findable it is, which is what this page is about.

Should I tag every conversation?

No. Tag the ones you would want to find as a group later, and let the rest be conversations.

Search, tags and fields do different jobs

Tool	Answers	Best for
Search	"Where is that customer?"	One person you can half-name
Tags	"Who is in this group?"	Everyone you might message together
Contact fields	"What do we know about them?"	Facts with a value — city, size, company
Notes	"What happened here?"	Context the transcript does not show
Status	"What still needs doing?"	The working queue

Reaching for the wrong one is the usual reason a team concludes the inbox is hard to search. A tag will never tell you what somebody's address is, and a field will never give you a list of everyone who complained last month.

Setting the cleanup thresholds

Start generously — a long inactivity window on the first run.
Run it once manually and look at what it would clear.
Tighten it only once you trust it.
Never rely on it for anything you must keep, because it removes every tag a contact has rather than the stale one.

Two numbers, one decision, and it keeps your audiences honest without anybody maintaining a list — which matters because reaching the right people is what keeps your quality rating healthy, and free conversations inside the 24-hour window under Meta's pricing documentation are only free if they are the right conversations to be having.

The five-second habits, ranked

Name the contact. Highest return of anything on this page — it makes search work at all.
Save an answer to a field the first time a customer tells you something durable.
Set the status when you finish, so the queue means something.
Write a note when the transcript alone would mislead.
Tag only when you can name the message you would send that group.

Done in that order, a team gets most of the benefit from the first 2. The fifth is the one people start with and it is the least valuable without the others.

What to do with a year of history

Once you have it, it is worth reading rather than only searching. An hour spent going through what customers actually asked over a month tells you which flow to build next, which product description is misleading, and which answer belongs in your knowledge base.

That is the same exercise behind a public FAQ page built from your WhatsApp answers, and the record you are searching is what makes it possible.

Common questions

Can I search inside message text?

Start with the chat list search for finding a person. For questions about what customers asked as a group, reading a month of conversations tells you more than any single search will.

What happens to tags when a contact comes back?

If the cleanup removed them, they are gone — tag them again if it still applies. That is the trade for keeping the list honest.

Should tags or fields hold an order number?

A field. It is a value, not a group.

Is there a limit on how many tags a contact can have?

The practical limit is your team's memory. Five meaningful tags beats forty nobody can define.

The short version

Name your contacts so search works. Put durable facts in fields, groups in tags, context in notes and the working queue in status. Turn on the stale-tag cleanup with generous thresholds, and remember it removes every tag a contact has rather than just the old one — so nothing important should live only as a tag.

A year of conversations is an asset or a haystack, and which one it becomes is decided by five-second habits rather than by any feature.

Why this matters more over time

In month one, everything is findable because there is not much. By month twelve you have thousands of conversations, several people who have joined since, and a customer on the phone asking about something they were told in March.

Nothing you can do in month twelve fixes that. The habits above are cheap while the inbox is small and impossible to apply retroactively, which is the argument for adopting them before they feel necessary.

If you are already a year in

Start the habits now and accept the backlog. There is no realistic way to retrospectively name thousands of contacts, and trying is how the project dies.

What is worth doing once is naming and tagging your best customers — the ones you would want to reach deliberately. That is usually a manageable number, it takes an afternoon, and it captures most of the practical value without pretending you can fix the whole history.

From that point the habits carry the rest. Every new conversation arrives named, tagged if it deserves it and noted where it matters, and within a few months the searchable portion of your inbox is the portion you actually use.
