Take a broker-dealer that sends a product brochure to 26 retail investors in one month. Under FINRA Rule 2210(b)(1)(A), “an appropriately qualified registered principal of the member must approve each retail communication before the earlier of its use or filing”. The principal reads it first. Nothing goes out until they have.
Now take the same firm’s adviser, who emails 25 retail investors in that month and says something just as promotional in the body of a reply. Rule 2210(a)(2) calls that “correspondence”, and Rule 2210(b)(2) gives it one sentence: “All correspondence is subject to the supervision and review requirements of Rules 3110(b) and 3110.06 through .09.” There is no pre-use approval. Review happens through the firm’s supervisory procedures, and Rule 3110.06 lets the firm decide how much of it to do on a risk basis.
The line between those two outcomes is a headcount: more than 25 retail investors in 30 calendar days, or 25 or fewer. The sentence on the page can be identical in both. That gap is where pre-send compliance sits, and this post defines it, shows what the rulebooks require around it, and says what it cannot do.
Pre-send compliance is the review of a message’s wording while it is still a draft, with the result shown to the writer so the writer can change it before it leaves. Three things in that sentence carry weight:
| Control | When it acts | What it looks at | Who decides | What it leaves behind |
|---|---|---|---|---|
| Pre-send compliance | While drafting | The wording of the draft | The writer | A corrected message, and a record of what was flagged |
| Pre-approval (for example FINRA 2210(b)(1)(A)) | Before first use | A fixed document | A principal or reviewer | A signed approval on a file |
| Data loss prevention | At send or on the gateway | Patterns: card numbers, labels, file types | A rule, then an administrator | A block or an alert |
| Archiving and supervision | After send | The stored record | A reviewer, later | A reviewed, retained message |
The practical test is simple. Ask what a control can still change. Pre-approval can change a brochure. Archiving can change nothing about the message, only what the firm does about it. Pre-send compliance can change the sentence, because the sentence has not left yet.
The two rulebooks read for this piece ask for three different things, and none of them is a pre-send review of an individual email.
Read together, the rules approve broad communications first, require a copy of everything, and leave the review of individual messages to risk-based procedures. The rule text is silent on the moment before send, which is the only moment at which the writer can still change the sentence.
One limit on this reading: it covers two rulebooks. Other regimes (SEC recordkeeping, MiFID II, sector rules outside financial services) ask for their own mixes of these three, and a firm subject to several should check each. Nothing found in the two read here makes pre-send review of correspondence a requirement. It is a voluntary control, which is worth knowing before anyone describes it to a board as “required”.
On 7 January 2021 the US Department of Justice announced that a global aircraft manufacturer had entered a deferred prosecution agreement over a conspiracy to defraud the FAA’s Aircraft Evaluation Group. The company agreed to pay a total criminal monetary amount of over USD 2.5 billion: USD 243.6 million as a criminal penalty, USD 1.77 billion in compensation to airline customers, and a USD 500 million fund for the beneficiaries of the 346 people who died in the two crashes. The Department’s own description of the conduct includes “misleading statements, half-truths, and omissions communicated by [the company’s] employees to the FAA”.
The company’s records system did its job. Messages written inside the company were captured, kept and later produced. What the control stack did not do was reach the writer at the moment of writing. A message that admits to misleading a regulator is a sentence a person types in a few seconds. Review after send could only read it.
VerbaPulse’s Benchmark Report 2026 tests this on documented language. We took 13 lines from real cases that ended in fines, settlements or judgments, each line quoted from the public record, and submitted every one to the live production API on 21 June 2026. Each raw response was stored with a SHA-256 stamp, and the server logs showed zero failed calls in that window, so a “no flag” is a model decision and never a silent error.
Nine of the thirteen lines were flagged with a severity, a category and a recommended action. Four returned no flag. Those four are ambiguous once they are stripped of the thread around them, and we publish them as such.
The output for the line from the aircraft-manufacturer case reads, as the API returned it: High, Legal. “I basically lied to the regulators (unknowingly).” Admission of lying to regulators. Recommended: no compliant version preserves the intent, best removed. That last clause is the behaviour to look for in any tool in this category. Some sentences have a safer version. Some should not be written, and a check that always produces a rewrite is hiding that.
These are famously bad sentences, picked because their words are on the public record, so 9 out of 13 says little about your inbox. Real mail is mostly mundane, context sits three messages up the thread, and an ambiguous sentence stays ambiguous.
Pre-send compliance targets accidental human risk: the careless line a well-intentioned person does not notice they are writing. It makes no claim to stop a determined insider or a deliberately evasive message, and it does not replace archiving, surveillance or the Rule 3110 review. It sits in front of them, so fewer problem sentences reach the queues that Smarsh, Proofpoint and similar systems feed. For how the two layers divide the work, see our comparison of pre-send and post-send compliance, and for how a compliance team runs it day to day, see VerbaPulse for compliance teams.
Take last month’s correspondence review output, whatever your firm calls it: the hits from the sampling, the lexicon alerts, the items an analyst escalated. For each hit, mark whether the problem was a sentence the writer could have changed in the compose window. The count tells you how much of your review effort is spent reading things that were still fixable when they were typed. That number is the case for a pre-send control, or the case against it, and you can have it by lunchtime.
A message to 25 readers and a message to 26 can carry the same sentence. Only one of them needed a principal’s signature before it left.
