Email marketing for financial advisors: write for the client review cycle, and treat every send to more than one person as an advertisement
The emails an advisory practice should send, how to grow the list, and what the SEC marketing rule and FINRA Rule 2210 mean for newsletters, testimonials and performance figures.
Published by AI Knows Us · Updated 21 October 2026
Email marketing for financial advisors works best as a steady, useful relationship channel: a monthly or quarterly market note, reminders tied to the client review and tax calendar, a welcome series for new clients and a slow nurture sequence for prospects. Write it in plain words from a named advisor, and send it through a platform your compliance team can archive. In the US, an email from a registered investment adviser that offers its services to more than one person is an advertisement under the SEC marketing rule, and an email from a broker-dealer to more than 25 retail investors in 30 days is a retail communication under FINRA Rule 2210 that a principal must approve before it goes out.
What email does for an advisory practice
Advisors win most new clients through referrals and introductions. Email supports both. It keeps existing clients informed and reassured, which is what makes them comfortable recommending you, and it gives a referred prospect a reason to stay in touch during the months before they are ready to move their money.
It is also the channel where your compliance obligations are easiest to meet, because every message is written, dated and stored. That is a strength. A practice with a clean archive of reviewed emails can send more often and with more confidence than one improvising on social media.
The emails worth sending
| When | Audience | |
|---|---|---|
| Welcome series | First 60 days after onboarding | New clients: who to call, what happens at the first review, how to read statements |
| Review reminder | Before each scheduled review | Clients: what to bring, what has changed in their life |
| Market or planning note | Monthly or quarterly | Clients and opted-in prospects |
| Tax and year-end checklist | Before year end | Clients: contributions, distributions, gifts, documents to send the CPA |
| Life event follow-up | After a client mentions retirement, a sale or a new child | One client, written personally |
| Prospect nurture | Monthly | People who attended a seminar or requested a guide |
The most read advisor emails are short and calm. In a volatile month, a three paragraph note explaining what you are watching and what clients do not need to do earns more trust than a long market recap.
The SEC marketing rule, for registered investment advisers
The SEC's marketing rule is 17 CFR 275.206(4)-1, read on 21 October 2026. It applies to advisers registered or required to be registered with the SEC. State-registered advisers should check their state's rules, which may differ.
When an email is an advertisement. The rule defines an advertisement as any direct or indirect communication an adviser makes 'to more than one person' that offers its investment advisory services with regard to securities to prospective clients, or offers new advisory services to current clients. Extemporaneous, live, oral communications are excluded. A newsletter or prospect email offering your services will usually fall inside that definition. An email to one client about their own account usually will not.
The general prohibitions. An advertisement may not include an untrue statement of a material fact, a material statement of fact the adviser cannot substantiate on demand by the SEC, or information likely to cause a misleading implication. It may not discuss potential benefits 'without providing fair and balanced treatment of any material risks or material limitations' associated with them, and it may not present performance results or specific investment advice in a way that is not fair and balanced.
Testimonials and endorsements. A client quote in an email is a testimonial. The rule requires a clear and prominent disclosure that it came from a current client, whether compensation was provided, and a brief statement of material conflicts of interest. Paid testimonials need a written agreement. Unpaid or minimally paid ones are exempt from the written agreement and disqualification conditions, but not from the disclosures.
Third-party ratings. If an email mentions a ranking or award, the adviser must clearly and prominently disclose the date the rating was given and the period it was based on, who created it, and whether the adviser paid in connection with it.
Performance. Gross performance must come with net performance of at least equal prominence, calculated over the same period and method. For a portfolio or composite other than a private fund, results must cover one, five and ten year periods with equal prominence, ending no earlier than the most recent calendar year end. The safest email policy for most practices is to leave performance out of mass emails entirely and discuss it in reviews.
Records. Under the books and records rule, 17 CFR 275.204-2(a)(11), an adviser keeps a copy of each advertisement it disseminates. Your email archive is that copy.
FINRA Rule 2210, for brokers and dual registrants
If you are a registered representative of a FINRA member firm, FINRA Rule 2210 applies to your emails, read on 21 October 2026. It sorts written communications by audience:
- Retail communication means any written or electronic communication 'distributed or made available to more than 25 retail investors within any 30 calendar-day period.' A registered principal must approve each one 'before the earlier of its use or filing' with FINRA's Advertising Regulation Department, unless an exception in the rule applies.
- Correspondence means a communication to 25 or fewer retail investors within any 30 calendar-day period. It is subject to the supervision and review requirements of Rules 3110(b) and 3110.06 through .09.
In practice, a monthly newsletter to your client list is a retail communication and goes through your firm's approval workflow. A personal follow-up to one client after a meeting is correspondence. Most broker-dealers require representatives to send marketing email only through an approved platform that archives it, so ask your compliance department which tools are approved before you sign up for one.
CAN-SPAM still applies
The securities rules sit on top of the CAN-SPAM Act. Under 15 U.S.C. 7704, a commercial email must give clear notice of how to opt out, honor opt-outs within 10 business days and include a valid physical postal address. A statement or account notice is relationship content, but a newsletter that promotes your services is commercial. This is general information, not legal or compliance advice. Your chief compliance officer has the final word for your practice.
Growing the list the right way
- Referral introductions. Ask permission before adding anyone a client introduced.
- Seminars and webinars. Registration includes an email and a clear opt-in.
- Useful guides. A retirement income checklist or a guide for a recently widowed spouse attracts exactly the prospects you want.
- Centers of influence. CPAs and estate attorneys who refer to you often want your quarterly note too.

Questions about email marketing for financial advisors
How often should a financial advisor send emails to clients?
Monthly or quarterly for the main note, plus review reminders and year-end checklists. Consistency matters more than frequency, and a reviewed quarterly note is better than a rushed weekly one.
Can a financial advisor use client testimonials in an email?
Under the SEC marketing rule, a registered investment adviser can, with clear and prominent disclosures that it came from a current client, whether compensation was paid, and any material conflicts. Broker-dealer representatives should follow their firm's policy under FINRA rules.
Does every advisor email need compliance approval?
For FINRA member firms, a retail communication to more than 25 retail investors in 30 days needs principal approval before use. For SEC-registered advisers, each advertisement must meet the marketing rule and be kept on file. Your firm's written policies decide the exact workflow.
Can I include performance numbers in a newsletter?
Only if the presentation meets the marketing rule, including net performance alongside gross and one, five and ten year periods for portfolios other than private funds. Many practices leave performance out of mass emails for that reason.
What email platform should a financial advisor use?
One your firm has approved and that archives every send. Ask compliance first, because a platform that is not approved can turn a good newsletter into a supervision problem.
The referral who asks an assistant first
A prospect who hears your name from a friend may still check before replying, and more of them now ask ChatGPT or Gemini what kind of advisor fits their situation, or who is well regarded locally for retirement planning. That answer comes from directories, firm pages and published profiles, not from your newsletter. Put the question your best prospect would ask and see which practices are named. AI Knows Us runs that check for firms that want to see it, alongside the compliance-reviewed work your email already does.
