The short version.
On 29 September 2026 SYNC had researched 2,225 companies. Of those, 972 had a dossier, and 423 had a dossier marked ready. That is 19% of the companies researched. The others were left alone, which in this piece means that SYNC holds the account and prepares no message for anyone there.[1]
One finding is about our own product. When we measured, this site stated the rule as “No dossier, no message. An account without a dated reason gets nothing from SYNC.” Of the 570 dossiers marked ready, 303 rest on a signal that has a source and a date. Another 230 rest on a signal that has a source and no date, and 37 have no reason recorded at all.
So the software did not enforce the rule as the site stated it. Today the check asks for a cited signal and its source, and does not require a date. We decided to keep this: a cited signal without a date can still make a dossier ready. The reviewer sees that the date is missing, and we are making that more visible in the review screen. The wording of the rule on this site now says a reason we can cite, not a dated reason. We also do not record why a company that never got a dossier was left alone.
Ready, without a date.
A dossier is the file SYNC writes on one company: what changed there, where we read it, who is in the buying group and how they can be reached. SYNC marks a dossier ready when it judges that there is a reason to write and a person to write to.
Together, 267 of the 570 ready dossiers (47%) have no dated reason on record, so they did not meet the rule as we stated it. The cause is in the check itself. It asks for a signal and for a link to the source of that signal. It does not ask for a date. When a date is present, the check uses it to see whether the signal is too old. A signal without a date can never be too old, so it passes. This was a choice made when the check was built, because requiring a date would have left most accounts waiting.
This means that a ready dossier tells you that SYNC found a cited signal. It does not tell you that the signal is recent. This count is about dossiers. It does not show how many messages were sent on a dossier without a date, and we make no claim about that here.
Why a dossier waits.
Left alone has an exact meaning here. It covers three states of a dossier: waiting (704), no case because no person at the company could be found (10), and unreachable because nobody found has a usable way to be contacted (6). Together that is 720 of 1,303 dossiers, or 55%. A further 13 dossiers are not judged yet, because SYNC does not know whether anyone can be reached. They are counted as neither ready nor left alone.
Every waiting dossier records one reason. The 704 waiting dossiers divide like this:
A weak signal has a source, but the research graded it as too thin to open a conversation with. “No dated, cited signal” is the wording of the recorded reason. In practice it is recorded when the signal or the link to its source is missing. Too old means that the signal has a date and that the date lies outside the window for that kind of signal. The window is 60 days unless a workspace has set another one.
The check stops at the first reason that applies, in the order above: missing, then weak, then old. A dossier with a signal that is both weak and old is counted as weak.
From researched company to ready dossier.
SYNC scores every researched company against the criteria of the workspace and gives it a tier from A to D. The table follows each company from research to a ready dossier, by its best tier.
| Best tier | Researched | With a dossier | With a ready dossier |
|---|---|---|---|
| A | 268 | 218 | 119 (44%) |
| B | 673 | 601 | 232 (34%) |
| C | 495 | 110 | 39 (8%) |
| D | 388 | 39 | 32 (8%) |
| Never scored | 401 | 4 | 1 |
| Total | 2,225 | 972 | 423 (19%) |
Even in tier A, fewer than half of the companies have a ready dossier. A good fit with the criteria does not give SYNC a reason to write. The 401 companies that were never scored are companies where the research failed, was skipped or has not finished.
Two things in this table need a warning. The rule for which companies get a dossier changed over time, so the tier C and D companies with a dossier come from the later rule. And 1,253 researched companies (2,225 less 972) have no dossier at all. For those we record no reason, so we cannot say why each of them was left alone.
What we decided.
We have not changed the check. Today the check asks for a cited signal and its source, and does not require a date. We decided to keep this: a cited signal without a date can still make a dossier ready. The reviewer sees that the date is missing, and we are making that more visible in the review screen. The wording of the rule on this site now says a reason we can cite, not a dated reason. On the count of 29 September, 267 ready dossiers have no dated reason on record.
SYNC records no reason for a researched company that does not get a dossier. Until it does, the first half of the funnel shows how many companies were left alone and not why.
What speaks against this.
Nobody knows what the accounts we left alone would have done. Some of them might have answered a message. We cannot say that the rule costs a share of anyone's pipeline, and we cannot say that it saves anything either. These numbers show what the rule holds back. They do not show whether holding back is right.
There is evidence that volume works. Gong, a vendor of sales software, reports from its own data that the average seller sends 344 cold emails to book one meeting.[2] A seller who wrote to all 2,225 companies would send more messages than a seller who writes to 423, and may book meetings that waiting misses. We found no independent study that compares the two ways of working.
Our own data has limits. It is the state on one day, and it holds no history: our record of changes of state starts on 25 September and contains two events. Dossiers and companies are different counts. One company can have several dossiers, and 1,303 dossiers cover 972 companies, so a share of dossiers is not a share of companies.
The count includes 403 archived dossiers. Without them, 389 companies have a ready dossier instead of 423. The dossiers come from five workspaces, which include our own and test workspaces. Each workspace sets its own criteria, so the tiers are pooled here as a funnel and say nothing about quality. This is not a sample of a market.
We counted every dossier in SYNC by its current state and by the fixed opening words of its recorded reason: 1,303 dossiers in five workspaces. We counted every researched company once per workspace, by its web domain and its best tier: 2,225 companies in nine workspaces. A company counts as having a ready dossier when at least one of its dossiers is ready.
Nothing was left out. Archived dossiers are included. The counts of 267 and 1,253 and the percentages are computed by us from the counts. The figures are for all workspaces together. We do not publish a split by workspace, because that would describe individual customers. The count was taken on the production database, read-only, on 29 September 2026 at 16:50 UTC, and it changes daily.
