An email signature is more than a name and job title at the bottom of an email. It's your digital business card, working quietly on your behalf with every message you send. A well-crafted signature tells recipients who you are, how to contact you, and can even guide them toward a next step like booking a call or visiting your website.
Despite this, many professionals still send emails without signatures. Others use signatures that are cluttered with information, out of date, or completely unreadable on mobile devices. Each of these scenarios wastes an opportunity to build credibility and make it easy for people to take action.
Our guide takes you through what to include in your signature, how to design something clean and professional, and the exact steps for creating signatures in both Gmail and Outlook. Along the way you'll find examples, tips for brand consistency, and answers to the most common signature questions.
A useful signature balances helpful detail with a clean, uncluttered layout. Aim for three to six lines when possible. Here's what to consider including:

Keep the signature readable across all devices. Use a single, system-friendly font like Arial, Calibri, or Helvetica in 10 to 12 point size. Left alignment is easiest to scan and displays consistently whether someone's reading on a laptop or checking email on their phone during a commute.
Before you start designing, choose the main purpose of your signature. What do you want it to achieve? This could be:
The most important thing: limit yourself to one call-to-action. Multiple CTAs dilute attention. If you ask someone to visit your website and book a call and connect on LinkedIn all at once, you'll likely get none of those outcomes. Pick one clear next step.
Design with hierarchy in mind. The most important information should be easiest to see. Forbes recommends putting effort into the visuals for your email signature so that whoever sees it will want to know more about you.
Start with your name on the first line. Put your title and company on the second line. Contact details come after that. Use smaller text or a muted color for secondary items like a tagline or personal motto.
If you want to include a logo or photo, keep it small and square. PNGs with transparent backgrounds work best and won't leave awkward white boxes in dark mode email clients. Avoid heavy images or banners that slow loading times or break in certain email programs.
Tip: Make sure every image has alt text and that your color contrast is suitable for readability. Not everyone views emails the same way, and a signature that's unreadable for some recipients isn’t doing its job.
Follow these steps for the web version of Gmail:
Tip: Send messages to yourself and view the results on both desktop and mobile to confirm that images and links display correctly. What looks perfect on your laptop might be a jumbled mess on a phone screen.
Outlook has slightly different processes depending on whether you're using the desktop app or Outlook on the web. Here's how to handle both.
Outlook desktop:
Outlook on the web:
Tip: Outlook can behave differently across versions and devices. If you manage email on multiple platforms, test each environment to make sure your signature displays consistently.
When you add social media icons, use small, standard icons and link directly to your profiles. For your call-to-action, choose one clear next step like "Schedule a demo" or "View my portfolio." Make sure the CTA link opens in a new tab and points to a mobile-friendly page.
Creating your signature isn't a one-and-done task. Here's how to keep it working effectively:
If you've added a scheduling link or other CTA, check your analytics after a month or two. If engagement is low, try adjusting the copy or testing a different action. Small tweaks can make a surprising difference.

Keep these guidelines in mind as you build your signature:
A concise, well-structured email signature does the heavy lifting of professional communication with very little effort from you. It tells recipients who you are, gives them a reliable way to reach you, and can guide them toward the next step like booking a call or visiting your website. Keep the design simple, prioritize the most useful details, and test across the environments your audience actually uses.
How long should my email signature be?
Aim for three to six lines. Keep it short enough to scan quickly but long enough to provide essential information. If you're stretching beyond six lines, you're probably including too much.
Can I use images or GIFs in my signature?
You can, but use them sparingly. A small logo or professional headshot is fine. Avoid large GIFs or banners that slow loading times or trigger spam filters. Remember that some email clients block images by default, so test your signature across devices and, ideally, multiple email platforms. If in doubt, don’t add an image.
Should replies include the full signature?
Not always. For long email threads, consider using a shorter signature for replies. Most email clients let you set one default signature for new messages and another for replies, which helps keep ongoing conversations tidy.
Is it okay to include personal social profiles?
Yes, if they're professional and relevant to your work. LinkedIn is generally the safest choice. Avoid personal platforms unless they actively support your professional identity.
Do signatures affect deliverability?
They can. Poorly formatted signatures or heavy image usage can increase the chance of landing in spam folders. Stick to simple HTML, avoid excessive links, and test deliverability if you're sending high volumes of email.
How do I make the signature mobile-friendly?
Use a single-column, left-aligned layout and avoid tiny font sizes that require zooming. Test on both iOS and Android mail apps since they can display content differently.
Can I track clicks in my email signature?
Yes. Use a UTM-tagged link or a URL shortener with tracking for your call-to-action. Monitor performance over time and adjust the CTA copy or destination page if engagement is lower than expected.
