Engineering firm email signature software for P.E. titles and firm numbers

In a consulting firm the signature block is where a graduate designer becomes a "Project Engineer" by accident, and where a principal's old license number outlives a renewal. AutoSignature puts P.E. only on licensed staff, names the state, adds the firm registration number and writes the result into every Outlook and Gmail mailbox from one template.

The short answer

Engineering firm email signature software sets one approved signature for everyone at a consulting firm, instead of letting each engineer, designer and coordinator keep their own. It fills in names, titles and phone numbers from your directory, holds the P.E. designation and license state per person so unlicensed staff never carry it, locks the firm name and registration number, and writes the result into each mailbox. Texas, Florida, California and New York all reserve engineering titles for license holders, and Texas names "signature" in its rule for firms. AutoSignature covers Microsoft 365 and Google Workspace on every plan, from $49 a month per firm billed yearly.

Can I put P.E. in my email signature

Yes, if you hold an active professional engineer license. Every state we read reserves the title for license holders. New York's rule is one sentence: only a person licensed or otherwise authorized "shall practice engineering or use the title professional engineer." Texas goes further and reserves "engineer" itself, with any variation or abbreviation.

The trouble in a firm is everyone else. A graduate two years from the exam, a CAD lead and a marketing coordinator all copy a signature from the person at the next desk. Titles like Project Engineer or Staff Engineer drift onto people who hold no license, and those emails go to clients, owners and plan reviewers.

The signature is the one place a title can be right on every message without anyone thinking about it. Rules differ by state, so have whoever owns licensing at the firm confirm the wording before you lock a template. This page is general information, not legal advice.

Engineer title and firm name rules by state

The rules that decide what belongs in an engineer's signature, read from the statute or regulation text. Each row can be a group template in AutoSignature, so a principal licensed in two states carries both lines and a designer carries neither.

StateRuleWhat it saysWhat it means for a signature
Texas, individualsOcc. Code 1001.301An unlicensed person may not use "engineer," "professional engineer," "licensed engineer," "registered engineer" or "engineered," or a variation or abbreviation, as a professional or business titleNo P.E. and no "engineer" job title on unlicensed staff who serve the public
Texas, in-house staffOcc. Code 1001.301(f)An exempt regular employee of a business entity may use "engineer" on a business card, cover letter or other correspondence if they do not offer engineering services to the publicCovers manufacturers and utilities, not the staff of a consulting firm selling design services
Texas, firmsOcc. Code 1001.405(e)A business entity may not use "engineer," "engineering," "engineering services" and similar terms in any "stationery, advertisement, signature, or business name" unless registered with the boardThe firm name line needs a current registration behind it
Texas, inactive license22 TAC 137.1(c)A holder on inactive status may use the terms but must include "inactive" or "retired" with the designationA retired founder's signature reads P.E. (retired)
Texas, firm number22 TAC 137.77(h)All engineering documents released by a registered firm, including preliminary documents, must clearly indicate the firm name and registration numberEmail is not named; the number in the signature travels with every transmittal
FloridaF.S. 471.031No title "tending to indicate that such person holds an active license as an engineer" unless licensed under the Florida chapter; the list runs from "civil engineer" and "structural engineer" to "software engineer"Branch titles count, and an inactive license does not
California, individualsB&P 6732Only a licensed professional engineer may use "professional engineer," "licensed engineer," "registered engineer," "consulting engineer" or branch titles such as "civil engineer" and "mechanical engineer""Consulting Engineer" and branch titles are reserved along with P.E.
California, firmsB&P 6738(a)(3)Any offer, promotion or advertisement that names an individual in the business "shall clearly and specifically designate the license or registration discipline of each individual named"Name the discipline next to the person, for example Civil Engineer, C 00000
New YorkEduc. Law 7202Only a person licensed or otherwise authorized may practice engineering or use the title "professional engineer"P.E. only on New York license holders writing to New York clients

Read in October 2026 from the Florida Statutes, the Texas Occupations Code and the California and New York codes as carried by public.law, and the Texas board rules as carried by Cornell's Legal Information Institute. None of these rules uses the word email. Texas comes closest, because its firm rule lists stationery and signature by name. Locked legal text per group works the same way as on our email signature disclaimer software page.

Should I list the states where I am licensed in my email signature

You are not ethically required to. The NSPE Board of Ethical Review took this exact question in Case 17-5, approved in January 2018. An engineer licensed in three states used a business email signature that did not say where he was licensed. The Board's conclusion: "It is ethical for Engineer A to not include the states in which he is licensed in his signature block."

The opinion carries a condition. It holds "unless there is some legal proscription" that requires the state to be shown, and as long as the engineer offers services only in states where he is licensed. Florida's statute, for one, ties engineering titles to a license "under this chapter," meaning a Florida license.

So most multi-state firms list the states anyway. It costs one line, it answers the first question an out-of-state client asks, and it removes any doubt about what the P.E. after the name refers to. The hard part is keeping forty of those lines current through renewals, new comity licenses and lapses.

Where engineering firm email signatures go wrong

Nobody misuses a title on purpose. It happens because eighty people across three offices each built their own signature the week they were hired.

The HR title is not the legal title

The directory says Project Engineer II because that is the pay grade. The person has not sat for the exam. The signature pulls the HR title straight into client email.

P.E. added a week early

Results come out, the office celebrates, and the designation is in the signature that afternoon. The license number is issued later. For that gap the title is not yet true.

A license that lapsed quietly

A principal lets a second state go inactive after the last project there closes. The signature still lists it two years on, in every email to every client.

The firm number nobody updated

A merger or a new entity brings a new registration. Title blocks get fixed because the CAD manager owns them. Signatures do not, because nobody does.

Transmittals from a phone

The desktop signature is correct. The revised calc package goes out from a job site at 6 pm with a first name and "sent from my phone," and no preliminary line at all.

Two brands after an acquisition

The acquired geotechnical office keeps its name for a year. Half its staff switch logos early, half never do, and clients cannot tell which firm they hired.

What should an engineer's email signature include

An engineer's email signature should include the name with P.E. only if licensed, the job title, the state of licensure, direct and mobile numbers, the firm name with its registration number where the state issues one, the office, and a line saying emailed drawings are preliminary unless signed and sealed. Here is where each line comes from in AutoSignature.

LineExampleWhere it comes from
Name and designationAndrea Kowalczyk, P.E.Directory name, plus a suffix held per person in the console and blank for unlicensed staff
Job titleSenior Structural Engineer, or Graduate DesignerDirectory title, with a per person override where the HR title is not one the board allows
License lineTexas P.E. #000000The department or group line of the template, one group per licensing state
Direct and mobileDirect +1 214 555 0146Directory phone fields; the mobile line shows only where it has a value
Firm name and numberTallgrass Engineering Group, Inc. Texas Registered Engineering Firm F-00000Locked in the template, identical on every mailbox in the firm
OfficeDallas office, tallgrasseng.exampleOffice field, so a move or a new branch updates every signature at once
Preliminary documents lineDrawings and calculations sent by email are preliminary and not for construction unless signed and sealed.Locked disclaimer block, on for the groups that send design documents
Seasonal bannerBridge inspection season is open. Ask for our 2027 scheduleScheduled with a start and end date on the email signature banners feature

Design-build firms that hold a contractor license as well need that number too, covered on construction company email signature software. If the firm's accounting arm signs with CPA, the same per person approach is on accountant email signature software.

Rolling it out across an engineering firm

Most firms are live the same afternoon. Nothing is installed on a workstation or a phone, and no engineer has to open a settings screen.

01

Connect the mail domain

Sign in to Microsoft 365 or Google Workspace as an administrator. Names, titles, offices and phone numbers come from the directory you already keep.

02

Mark who is licensed

Work down your license roster once. P.E., S.E. or EIT goes next to each name, and any title the board would not accept gets an override.

03

One template per group

Licensed engineers by state, EITs and designers, CAD, marketing and administration. Same logo and firm number, different lines underneath.

04

Apply and keep it applied

Signatures are written into each mailbox. New hires have theirs on day one, departures are cleared, and every change is versioned with one step rollback.

Step by step on centralized email signature management. Firms on Outlook should read Office 365 email signature management, and those on Gmail Google Workspace email signature management.

Who buys this

20 to 150 staff

Civil and structural consultants

Big enough that a principal cannot read every signature, small enough that IT is an outside provider and licensing is tracked in the office manager's spreadsheet.

Several states

Multi-state MEP firms

One group per state of licensure puts the right line on each engineer, and a new comity license is one change instead of a reminder email.

Mixed credentials

A/E and survey firms

Architects, engineers and surveyors each have their own reserved titles. Designations held per person keep AIA, P.E. and RPLS on the right names. The architect side is on architecture firm email signature software.

Field heavy

Geotechnical and testing labs

Technicians email reports from the field every day. A short signature for them, with the firm number and no engineer title, is the one to get right first.

After a deal closes

Firms that merge or rebrand

A new entity means a new firm registration and a new logo on a set date. Switching every mailbox in one rollout is the cleanest day one task there is.

A note on fit

Sole practitioners

One engineer with one mailbox can set a signature by hand in two minutes. This page is written for firms with enough people that signatures drift.

Engineer email signature questions

Can I put P.E. in my email signature?

Yes, if you hold an active professional engineer license. Texas, Florida, California and New York all reserve the title for license holders, and Texas makes a holder on inactive status add the word inactive or retired. If you write to clients in a state where you are not licensed, name the state that issued your license.

Can an EIT use the title engineer in an email signature?

It depends on the state. Texas Occupations Code 1001.301 bars an unlicensed person from using engineer or any variation of it as a professional or business title, with a narrow exemption for in-house employees who do not offer services to the public. Most consulting firms use EIT, Graduate Engineer where allowed, or Designer.

Should I list the states where I am licensed in my email signature?

You are not ethically required to. In Case 17-5 the NSPE Board of Ethical Review found it ethical for an engineer licensed in three states to leave them out of his signature block, unless a law says otherwise. Firms that work across state lines usually list them anyway, because it answers the client's first question.

Does an engineering firm need its registration number in emails?

No rule we read names email. Texas rule 137.77 requires every engineering document a registered firm releases, including preliminary documents, to show the firm name and registration number. Drawings and calculations leave by email all day, so Texas firms commonly put the F number in the signature so it travels with each transmittal.

What should an engineer's email signature include?

An engineer's email signature should include the name with the P.E. designation only if licensed, the job title, the state of licensure, direct and mobile numbers, the firm name with its registration number where the state issues one, the office, and a line saying emailed drawings are preliminary unless signed and sealed.

Can a company use the word engineering in its email signature without a firm registration?

Not in Texas. Occupations Code 1001.405 bars a business entity from using engineer, engineering, engineering services or similar terms in any stationery, advertisement, signature or business name unless the entity is registered with the board and its engineering work is done or supervised by a licensed engineer.

Can an engineering firm manage every employee's email signature from one place?

Yes, when the firm owns its mail domain on Microsoft 365 or Google Workspace. AutoSignature writes the approved signature into every mailbox, so it shows in Outlook and Gmail on the desktop and in the browser, and a new P.E. gets the designation in one change the day the license is issued.
