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.

Seeing your Instagram post shared by someone else is one of the best forms of organic marketing you can get. It’s digital word-of-mouth, expanding your reach to new audiences and building serious social proof for your brand. This article covers the exact settings you need to enable and the content strategies that make people genuinely want to share your work.
Before we get into the "how," let's quickly cover the "why." When someone reposts your content, it’s not just a vanity metric. It's a powerful endorsement. This user-generated content (UGC) accomplishes several things at once:
Instagram gives you specific tools to make sharing easy. If people tell you they can’t share your posts to their Stories, it's likely a setting is turned off. Here’s how to check and fix it.
This is the most common and important setting. It allows anyone to take a public feed post or Reel and share it as a sticker in their own Instagram Story. When they do, the story will show your username and link back to your original post, driving traffic and new eyes to your profile.
Here’s how to enable it:
That's it! Once enabled, when someone taps the paper airplane (share) icon on your post, they will see the option to "Add to story." If this setting is off, that option won’t appear for them.
For Reels, the options under Sharing and remixes are even more detailed. You have control over who can share, use, and download your content.
For a brand looking to grow, keeping these sharing and remixing settings turned on is almost always the right move. You’re giving your audience more ways to engage with and amplify your content for you.
The "Invite Collaborator" feature is a different kind of sharing - it's co-authoring. When you invite a collaborator to a post, the post appears on both of your profiles simultaneously. It shares the same set of likes and comments, essentially merging the audiences for that single post. This is perfect for partnerships, influencer campaigns, or collaborations with other brands.
When to use the Collab feature:
How to invite a collaborator:
Just because the "share" button is available doesn't mean people will use it. Your next job is to create content so good, so helpful, or so relatable that sharing it feels natural. Here’s how you do it.
Content that educates or helps people solve a problem is ripe for sharing. Think about what your audience struggles with or wants to learn. Turn that expertise into a visually appealing format.
Great examples include:
When you create content that makes someone else look smart and helpful by sharing it, they will. People love sharing resources that benefit their own audiences.
Emotion drives shares. Memes, relatable quotes, funny videos, and inspiring stories connect with people on a personal level. If a post makes someone say, "That's so me," or "Wow, I needed to hear that," there's a strong chance they'll share it to their Story.
Don’t be afraid to show personality. A perfectly curated feed is nice, but it's often the behind-the-scenes, humorous, or human moments that get the most shares.
Sometimes a share is driven by pure aesthetics. A breathtaking travel photo, a beautifully styled product shot, or a slickly edited Reel can earn a share simply because it’s a piece of art that someone wants to display on their digital "wall" (their Story).
Invest in good lighting, learn basic photo editing, and focus on creating a strong visual identity. People are more likely to share content that reflects well on them and aligns with their own aesthetic.
Don't be afraid to ask for the share! Sometimes people just need a little nudge. You can bake this into your caption or even add text directly on your image or video.
Effective sharing CTAs include:
This simple act can dramatically increase the number of shares you receive, especially on posts designed to connect with a specific viewpoint or emotion.
An excellent proactive strategy is to build a campaign around reposting. The concept is simple: ask your audience to post about your brand or product using a specific hashtag for a chance to be featured on your page.
Here’s how it works:
This creates a win-win: your audience gets a shot at recognition from a brand they admire, and you get a steady stream of authentic, powerful customer content to share.
Finally, it's just as important to model good behavior. When you ask others to share your work, make sure you're respecting the creator community when you share theirs.
This is non-negotiable. If you are reposting a photo, Reel, or Story from a customer or another creator, you must give them clear credit. Don’t hide their handle at the bottom of a long caption or bury it in a sea of hashtags. Tag them in the photo/video itself and mention their username prominently in the first line of the caption (e.g., "📸 Photo by @username"). This fosters goodwill and encourages more people to share content with you in the future.
To make it easier for others to credit you, consider adding a subtle watermark of your @username to your photos or videos. This ensures that even if your content is shared without a proper caption, the source is still visible.
Enabling others to repost your Instagram content is a powerful growth strategy. By combining the right technical settings with a creative approach that produces share-worthy posts, you turn your audience into an active and enthusiastic marketing force. It's about making it effortless for people to share and giving them amazing content they're proud to amplify.
Planning and executing a content strategy that consistently produces that "repost-worthy" material is the toughest part. Seeing your content calendar visually helps immensely when trying to build educational carousels, schedule inspiring moments, or plan a full UGC campaign.
