An email signature is the smallest piece of marketing you produce, and it goes out more often than any other. It appears on every reply, every listing inquiry, every note to a buyer's agent. If the identification the rules ask for is in the signature, it is in every message. If it is not, it depends on memory.
Illinois has a specific rule about electronic communication by licensees. This article covers what it requires in a first message, what a signature should contain beyond that, and how to design one that reads cleanly on a phone.
This is not legal advice. Rules change, and your brokerage may have stricter policies of its own. Confirm anything that matters with your managing broker before you rely on it.
What the rule asks for
Section 1450.720 of the Illinois Administrative Code, Title 68, Part 1450 is titled Digital or Electronic Advertising and Communication. Subsection (g) covers licensee electronic or digital communication. A licensee engaged in licensed activities using any electronic or digital means of communication must include the following in "the initial communication with a member of the public or another licensee":
- The licensee's name as licensed with the Division or, if applicable, the name registered with the Division. If the licensee is part of a team, the team name may be used in addition to the individual licensee's name.
- The sponsoring broker's name.
- The city and state where the sponsoring broker's physical office registered with the Division is located or, in the case of a virtual office, a direct link that connects to the virtual office website or digital platform.
Subsection (f) sets the matching requirement for a sponsoring broker's own electronic communication: the broker's name, and the city and state of the principal physical office or other registered offices, or a direct link.
Two points follow from the wording.
The rule is about the first communication. The requirement attaches to the initial communication with a member of the public or another licensee. A signature that carries the information on every message satisfies it without anyone deciding which message is the first.
It covers electronic means generally. The rule says "any electronic or digital means of communicating." Email is the obvious case. Whether a text or a social message counts is a question for your managing broker, and a standing line that you can paste into any of them solves the practical problem.
Related rules for the signature
Prospecting counts as advertising
Section 1450.715(d) says "unsolicited marketing of licensed activities and prospecting for clients by licensees shall be considered advertising." A cold email to a homeowner is advertising under the rule, which brings in the sponsoring broker's name requirement of Section 1450.715(b). The signature is the natural place to meet it.
Designated managing brokers
Section 1450.715(f) says licensees registered with the Division as designated managing brokers "shall indicate that status in any marketing or advertising that includes their name," except on for sale signs placed on real property. If this describes you, ask your managing broker whether your signature should carry the designation. It is an inexpensive way to be sure.
Links to required disclosures
Section 1450.720(j) says licensees using websites or digital platforms for advertising "must provide a direct link" to required disclosures about the sponsoring broker's name and other relevant business information, along with the terms of any offers or inducements. If your email links out to a landing page, that page is the digital platform. Ask your brokerage which page holds its disclosures.
Keeping information current
Section 1450.720(i) requires licensees to periodically review advertising and marketing information on their websites and digital platforms and update it so that it is "current and not misleading." A signature template that is shared across a team deserves the same review: team names change, offices move, and old lines linger.
What a signature should contain
The rule sets a floor. The best signatures stay close to that floor and add only what a recipient needs.
Required elements
- Licensed name, or your team name in addition to it
- Sponsoring broker's name, spelled out
- Office city and state, or a direct link to the brokerage's virtual office
Useful additions
- A direct phone number
- Your designated managing broker status, if it applies
- A single link to your website
Leave out
- A page of badges, awards and quotations
- Several fonts and colors
- A photograph large enough to dominate a phone screen
An example signature
[Licensed name] [Team name, if applicable] [Brokerage name], [office city], Illinois [Direct phone number] | [Website]
Four lines. The first holds the licensed name, the second the team, the third carries the brokerage name with the office city and state, and the fourth gives the means of contact. If you are a designated managing broker, add the title on the first line.
Designing it so it holds up
A signature is seen on screens of every size, in clients that handle images differently. A few decisions keep it legible. The same signature belongs at the foot of a monthly email letter.
- Use live text for the identification. If the brokerage name exists only inside an image, a client that blocks images shows nothing, and a screen reader says nothing. Text is the safer carrier for the required lines.
- Keep the logo small, and make it optional. If you include one, treat it as decoration. The text lines meet the requirement on their own.
- Use a system-safe typeface for the text. The signature will be rendered in whatever the recipient's client offers. Choose a plain family and let the layout rely on spacing and weight rather than on a particular font.
- Test on a phone. Send the signature to yourself and read it on a small screen. If the brokerage name wraps awkwardly or the lines collapse together, adjust the line length.
- Use one signature for new messages and a shorter one for replies, if your mail client allows. Both should carry the required lines. The shorter one can omit the website.
The brokerage-name-size question
The size rule in Section 1450.715(b) applies to advertising in general, and an email signature is not usually where a team name and a brokerage name compete for space. Still, if the signature carries a team name, set the brokerage name in a size at least equal to it. Our piece on brokerage name size explains the three tests.
Team signatures
On a team, one person usually builds the signature and everyone copies it. That is efficient and it is also how errors spread. Before a template goes out to the team:
- Confirm each person's licensed name as it appears with the Division.
- Confirm the team name and its approval, if the brokerage requires one. Our note on team names in Illinois covers the words to watch.
- Confirm the office city and state for each person, since not everyone on a team works from the same office.
Marketing emails are a different layer
A signature covers one-to-one correspondence. A listing announcement or monthly letter sent to a list carries its own layout, with its own header and footer. The same identification belongs in the footer of those pieces. Marketing email is also subject to federal commercial email rules, including a working way to opt out, which are outside the scope of the Illinois sections we read here. Your brokerage's email platform usually handles the opt-out mechanics. Layout for those is in listing announcement emails that load and read on a phone.
A short checklist
- Is your licensed name in the signature, with the team name added if you use one?
- Is the sponsoring broker's name spelled out in text?
- Is the office city and state present, or a direct link for a virtual office?
- If you are a designated managing broker, is that status stated?
- Does the signature read cleanly on a phone?
- Has anyone reviewed it since the last change in team, office or brokerage?
A signature that carries the right lines will do the job every time without a second thought. If you would like a clean, consistent set of email graphics, including signature and announcement templates with the identification built in, that is the work we do.
