How to use

Three steps. Under a minute.

  1. 01

    Fill in your details

    Name, title, company, contact info. Optionally upload a photo or company logo and set an accent color.

  2. 02

    Pick a layout

    Stacked is the standard photo + contact format. Horizontal is compact. Minimal is text-only.

  3. 03

    Copy and paste

    Hit Copy signature, then paste into Gmail's, Outlook's, or Apple Mail's signature settings. The formatting and photo come through intact.

The anatomy of a good email signature

A signature is a small piece of UX that gets rendered millions of times. The same design rules apply as anywhere else — clarity, hierarchy, restraint.

Name and title — the two lines that earn their space

The first line of a signature is the only one most recipients actually read. Your name should be the largest, boldest element; your title and company sit immediately below in a smaller weight. Avoid putting credentials and post-nominals (PhD, MBA, CFA) in the name line unless you're sending into a context where they matter — they create visual noise and read as defensive.

Contact — only what they'll actually use

Your signature does not need to list every way the recipient could contact you. It needs to list one or two. For most people that's email and one URL — your phone number is already in their CRM, and the address rarely matters. If your role makes the phone genuinely useful (sales, support, customer success), keep it. Otherwise cut it. The same logic applies to social handles: a single linked website is usually enough.

Photo or logo — pick one

Headshots humanize the email; logos brand the email. Don't do both. For one-to-one outreach (sales, partnerships, founder updates) the headshot performs better. For broadcast or operational email (support replies, automated notifications) the logo performs better. The stacked layout is built around a photo at 72px; the minimal layout omits the photo entirely for cases where you want a text-only signature.

Color — one accent is plenty

The color picker in this tool sets a single accent — used for your name and your linked email/URL. That's deliberate. Two or more colors in a signature read as templated and corporate; a single accent reads as designed. Pick a color that has enough contrast against white (recipients' inbox background); the default is a deep green that sits at a readable contrast ratio for normal text size.

Taglines — usually a mistake, sometimes useful

Most taglines are noise: "Helping companies grow through data-driven solutions" is the kind of line that makes a recipient less likely to take you seriously. The taglines that work are short, specific, and earned — a recent product launch, a current focus, a small piece of personality ("Currently: hiring a designer"). The tagline field is optional for that reason — leave it blank unless you have something specific to put there.

Mobile rendering

Roughly half of all email is opened on mobile, where signatures often render at full width without the surrounding email shell. The table-based layouts this tool generates all reflow gracefully on small screens — the photo and contact details stack vertically in the stacked layout, and the horizontal layout collapses to a single column. If you want to test, send yourself the email and open it on your phone before installing the signature in your client.

Student email signature generator: signatures for university and grad applications

A student email signature has a narrower job than a professional one: identify the institution, name the program, and provide one direct way to follow up. For undergrads emailing professors, internships, and admissions offices, the formula is name + degree path + university + a single line of contact: "Sarah Chen — BS Computer Science, MIT '27". For grad students emailing prospective advisors, research collaborators, or conference contacts, add the lab or department: "Sarah Chen — PhD Candidate, Chen Lab, Stanford CS". Skip the inspirational quote, the campus address, the social handles — they read as visual noise to busy faculty. The minimal layout this generator produces matches the student context exactly: clean, no logo, a single accent color, optionally a small headshot if you're applying for things that benefit from putting a face to the name (TAships, fellowships, lab visits).

Real estate email signature generator: license, photo, broker fields

Real estate signatures have legal and trust requirements that other industries don't. State licensing rules in most US markets require agents to display their license number on outbound communication, and the broker affiliation needs to appear alongside the agent's name. A real estate email signature generator built for this surface includes the right fields by default: name, designation (REALTOR®, Associate Broker), license number, brokerage name, brokerage address, direct phone, brokerage phone. Add a headshot for client-facing email — buyers and sellers respond measurably better when they can put a face to outreach — and use the brokerage's accent color rather than your own. One thing the layout has to handle well: the brokerage logo needs to render at small sizes (most clients view email on mobile) without losing legibility, which is why a separate company-logo field that sits next to the photo is part of the standard real-estate format.

Email signature generator for Mac Mail and Apple Mail

Mac Mail (also called Apple Mail) has a specific quirk that breaks most signature generators: by default, it overrides custom signature formatting with the system's default font and color. Pasting in a beautifully formatted HTML signature and watching it render as plain Helvetica is a common frustration. The fix is two steps: paste the signature into the Apple Mail signature editor as expected, then uncheck the box labeled "Always match my default message font" in the right-hand pane of Mail → Settings → Signatures. With that box unchecked, Apple Mail preserves the HTML, the colors, the font, and any embedded photo. The table-based output from this generator is designed to survive Apple Mail's rendering — including the data-URL photo embedding, which never breaks because of remote-image blocking the way externally hosted signature photos sometimes do.
