How to Add Social Media Icons to an Email Signature
Enhance your email signature by adding social media icons. Discover step-by-step instructions to turn every email into a powerful marketing tool.

Your Instagram bio only provides you with one clickable link, so you have to make it count. That single link needs to do a lot of work - directing your followers to your new blog post, online store, latest YouTube video, and all other important places you exist online. This guide breaks down how to use a simple tool called Linktree to turn that one link into a gateway for all your content, making it easy for your audience to find everything you offer.
At its core, Linktree is a "link in bio" tool that solves Instagram's biggest limitation: the inability to share multiple hyperlinks on your profile. Instead of constantly swapping out the link in your bio every time you have something new to promote, Linktree gives you a single, permanent link. When users click this link, they land on a simple, customizable page that lists all your other important links.
Think of it as a launchpad for your audience. With one tap, they can go from your Instagram profile to:
By consolidating your links this way, you remove friction. You’re no longer forcing followers to search for your blog or guess your YouTube handle. Instead, you guide them directly where you want them to go, which is a game-changer for driving traffic and growing your brand across different platforms.
Getting your Linktree page live is a quick process. Here’s a breakdown of how to get started, from creating an account to being ready to add your links.
First, head over to the Linktree website. You'll see the option to sign up. You can create an account with your email or connect a social profile to speed things up. The most important choice you'll make here is your Linktree username.
Pro Tip: Choose a username that matches your Instagram handle or brand name. This keeps your branding consistent and makes your link look trustworthy and recognizable to your followers. Your final Linktree URL will be linktr.ee/yourusername.
Next, Linktree will ask you to categorize your account. You’ll be prompted to choose a category that best describes your brand, such as Influencer, Business, Musician, or Education. This helps them tailor the experience, but don’t overthink it - just pick the one that feels closest to what you do.
Linktree offers both a free plan and several paid subscription tiers. For most creators and small businesses just starting out, the free plan is more than enough. It gives you:
The paid plans offer advanced features like more customization options, detailed analytics for each link, email integrations, and priority support. You can always start with the free plan and upgrade later if you find you need more features.
Once your account is created, you’ll be taken to your admin dashboard. This is where the magic happens. A default, undecorated Linktree might not inspire clicks, so take a few minutes to customize it to reflect your brand's personality and style.
Your main workspace is the “Links” tab. Look for a button that says “Add link.” Clicking this will open up a new module where you can enter a URL and a title.
Repeat this process for all the links you want to feature. To reorder them, just click and drag the links up or down. A good strategy is to place your most important or time-sensitive link at the top, like a new product launch or a ticket sale for an event.
Now, head over to the “Appearance” tab. This is where you can align the visual identity of your Linktree page with your brand.
First, add your profile picture and title. For consistency, use the same profile picture as your Instagram account. Your profile title should be your name or brand name. You can also add a short bio underneath to give visitors a bit more context about who you are and what you offer.
Here you can change the colors, background, and button styles of your page. The free plan comes with a solid selection of pre-made themes. While you can't choose exact hex codes without a paid plan, you can pick a theme that closely matches your brand's color palette. A visually cohesive experience builds trust and makes your page feel professional.
With your Linktree page set up and customized, it’s time for the final and most important step: adding it to your Instagram bio so it's clickable for all your followers.
Go back to your Linktree admin dashboard. In the top right corner of the page, you'll see your unique Linktree URL (e.g., linktr.ee/yourusername). Click the "Share" button next to it and then "Copy" to get the link.
Open the Instagram app on your phone and navigate to your profile page by tapping your profile picture in the bottom right corner.
Right below your bio and follower count, you’ll see the “Edit Profile” button. Tap on it to open up the editing screen for your profile information.
On the "Edit Profile" screen, you will see a field labeled "Website." This is the only place on your profile where a URL will be clickable. Do not make the common mistake of pasting your link into the "Bio" text area - it won’t work. Tap into the "Website" field and paste your copied Linktree URL.
Once you’ve pasted the link, tap "Done" or the checkmark in the top right corner to save your changes. Instagram will take you back to your profile. You should now see your Linktree URL displayed proudly in your bio. Tap on it yourself to make sure it works correctly and takes you to your awesome new links page!
Simply having a Linktree isn't enough, you need to manage it effectively to get the most value out of it. Here are some strategies to turn your link page into a powerful tool for your brand.
It's tempting to add a link to every single thing you've ever created, but resist the urge. A long, cluttered list can cause decision fatigue, leading users to click nothing at all. Stick to 3-5 essential links that represent your current priorities. This makes it easy for visitors to find what matters most.
Vague titles get ignored. Instead of a title like "Blog," use something more specific and compelling like “5 Tips for Better Social Media Photos.” Instead of “Shop,” try a title like “Shop the New Summer Collection.” Use verbs and be specific about the value a user will get when they click.
Your "link in bio" is a destination. You need to actively send people there. In your Instagram post captions, always add a call-to-action like "Click the link in my bio to learn more" or "Shop the full collection via the link in our bio." The same goes for your Stories and Reels. Use Instagram's "link" sticker in Stories to create a direct path for your followers.
Your Linktree should be a living page, not something you set and forget. Check your performance weekly. Linktree’s free plan shows you how many times your page has been viewed and how many total clicks you've received. Use this information to see what's resonating. Swap out old or underperforming links with fresh content, seasonal promotions, or your most recent creations.
Adding a Linktree to your Instagram bio is a simple yet powerful way to overcome the platform's one-link limit, making it easier for your audience to connect with you across all your channels. By following these steps, you can create a branded, easy-to-navigate landing page that serves as the perfect hub for your community.
Once your link in bio is optimized, the next part of the process is creating consistent content that gives people a reason to click it. We built Postbase to streamline exactly that. Our platform helps you see your entire content plan in a visual calendar, schedule posts for all your accounts in one go, and analyze what's driving results, allowing you to spend less time managing the chaos and more time creating.
