Private placements — securities offerings sold without full SEC registration — rely on exemptions provided by Regulation D, and marketing them is governed by securities law most marketers never encounter. This article explains, in general educational terms, what Regulation D is, how its exemptions shape private-placement marketing, and what marketers need to understand. It is not legal advice; securities marketing requires qualified counsel.
What Regulation D provides
Securities offered to the public generally must be registered with the SEC — an expensive, demanding process.
Regulation D provides exemptions that allow companies to raise capital through
private placements without full registration, under defined conditions. It’s the framework most private capital-raising relies on.

The key exemptions under Regulation D for marketers are the Rule 506 exemptions:
Rule 506(b) permits raising unlimited capital from accredited investors plus a limited number of sophisticated non-accredited investors — but does
not permit general solicitation or advertising. Offerings rely on pre-existing relationships, and accredited status can generally be self-certified.
Rule 506(c) permits general solicitation and advertising — public marketing of the offering — but requires that all purchasers be accredited investors and that the issuer take reasonable steps to verify their accredited status.
The distinction matters enormously for marketers: under 506(b), you generally can’t advertise the offering publicly; under 506(c), you can, but with the accredited-only restriction and verification requirement. Which exemption an offering uses determines what marketing is permissible. This choice, and compliance with the chosen exemption, are legal decisions for the issuer and their securities counsel.
Common questions
What is Regulation D in private-placement marketing?
Regulation D provides exemptions that allow certain securities offerings to avoid full SEC registration requirements. For private placements, the two rules most commonly discussed are Rule 506(b) and Rule 506(c). Rule 506(b) generally prohibits general solicitation, while Rule 506(c) permits general solicitation if all purchasers are accredited investors and the issuer takes reasonable steps to verify that status.
What is the difference between Rule 506(b) and Rule 506(c)?
The biggest marketing difference is whether the issuer can publicly advertise the offering. Rule 506(b) generally prohibits general solicitation and permits sales to accredited investors plus up to 35 non-accredited investors who meet specified sophistication requirements. Rule 506(c) permits general solicitation, but every purchaser must be accredited and the issuer must take reasonable steps to verify accredited-investor status.
Can you advertise a Rule 506(c) private placement online?
Generally, yes. Rule 506(c) specifically permits general solicitation and advertising, which can include digital marketing, subject to the requirements of the exemption. However, being allowed to advertise does not mean every marketing tactic is automatically compliant. The issuer still needs to satisfy the accredited-investor requirements and other Regulation D conditions, and securities-law anti-fraud rules continue to apply.
Can you use an accredited-investor email list for Rule 506(c) marketing?
An investor database can potentially be used as part of a Rule 506(c) marketing strategy, but a database label such as “accredited investor” does not by itself satisfy the issuer’s verification obligation. Under Rule 506(c), the issuer must take reasonable steps to verify accredited status. The SEC specifically notes that simply having an investor check a box or self-certify, without additional supporting information, is not sufficient.
Does an accredited-investor list prove someone is accredited?
No. A third-party list can be useful for identifying potential investors, but it should not automatically be treated as proof of current accredited-investor status. Under Rule 506(c), verification is a separate requirement. Depending on the circumstances, verification can involve financial documentation, written confirmation from certain qualified professionals, or other reasonable methods.
How does accredited-investor verification work under Rule 506(c)?
The SEC describes a principles-based approach that considers the investor, the information available about that investor, and the nature of the offering and solicitation. The rule also provides non-exclusive verification methods, including reviewing specified income documentation, reviewing certain net-worth documentation, or obtaining written confirmation from a registered broker-dealer, SEC-registered investment adviser, licensed attorney, or CPA.
What should private-placement marketers look for in an investor database?
Focus on data provenance, freshness, investor type, geographic coverage, contact accuracy, firm or individual classification, and documentation supporting any accredited-investor designation. A useful database should help identify potentially relevant investors, but it should not be represented as replacing the issuer’s legal and verification processes. Buyers should also understand exactly how the provider sourced the information and what rights they have to use it for solicitation.
What is the biggest mistake when marketing a Regulation D private placement?
The biggest mistake is treating “accredited investor” as a simple marketing-list filter rather than a legal qualification that must be handled according to the applicable offering exemption. An issuer can potentially use broad solicitation under Rule 506(c), but it must still ensure that all purchasers are accredited and take the required reasonable verification steps. For Rule 506(b), broad public solicitation creates a fundamentally different issue because general solicitation is generally prohibited.
How this applies to your business
If you market private placements, the exemption framework governs everything — including whether you can advertise at all. Under Rule 506(b) you generally can’t publicly market the offering; under 506(c) you can, but only to verified accredited investors. Before any marketing, the offering’s exemption must be established by counsel, because it determines what marketing is permissible. Treat the exemption as the foundation your marketing is built on, not a detail to confirm later.
Work with qualified securities counsel throughout, and keep the marketer/lawyer division clear. Audience identification and exemption-appropriate messaging are marketing’s role; exemption selection, compliance, and accredited-status verification are legal. The verification requirement under 506(c) and the advertising prohibition under 506(b) are precisely where getting it wrong loses the exemption — squarely legal territory. This article is general educational information, not legal advice; consult a securities attorney for your situation.
Use accredited-investor data within the framework counsel establishes. Quality data helps identify and reach potential investors, but it operates inside the exemption’s constraints — it doesn’t substitute for securities-law compliance. Treat investor data as one input into a legally structured offering process, used in the manner the chosen exemption permits.
