link in bioThe short answer
Put your Substack address on one page next to your latest issue, your other accounts and a contact form, and use that page's address in your Instagram and TikTok bios. Linkerzz does not run your mailing list: people subscribe on Substack.
Linkerzz makes a link-in-bio page builder and is not affiliated with Instagram, TikTok or any other app named here. Facts about other apps were checked on October 24, 2026. Apps change their menus often, so trust the app's own help page if yours looks different.
On this page
If you write a newsletter, your social profiles have one job: send people to it. A profile only has room for a few links, and the one you most want people to tap changes with every issue. A single page solves that. You put its address in your Instagram and TikTok bios once, and you change what is on the page.
The quick way: put your Substack link in your Instagram bio
If you only want to send people to your newsletter, you can add your Substack address to your profile directly. These steps come from Instagram’s Help Center.
- Tap your profile picture in the bottom right to open your profile.
- Tap Edit profile.
- Tap Links, then Add external link (iPhone) or Add link (Android).
- Paste your Substack address, such as
yourname.substack.com, and tap Done.
Instagram says you can add up to 5 websites, and anyone, on or off Instagram, can see them. The full walk-through is in how to add a link to your Instagram bio.
That works well for one link. But a newsletter usually comes with a podcast, a shop, a contact page and your other accounts, and five links go quickly. That is when one page helps.
What to put on the page
- A button for your newsletter, first. Use a link block with plain words, for example “Read the latest issue” or “Subscribe to the newsletter”. Add a second line saying what it is about and how often it comes out.
- Your Substack icon. Linkerzz has a Substack icon in its row of social icons. Paste your Substack address, such as
yourname.substack.com, and it appears as a round button next to your other accounts. - Your other accounts. Instagram, TikTok, YouTube, LinkedIn and more, as icons in the same row.
- A contact form. Readers, collaborators and brands can write to you from the page. Messages land in your inbox on Linkerzz, and on Pro you also get an email for each one.
- A podcast or video, if you have one. A Spotify or YouTube card shows a player that loads only when someone taps it, and the free plan allows one.
- A kind word from a reader. Add a testimonial block, but only use words a reader really said.
Substack addresses on your own domain
The Substack icon accepts substack.com addresses only. If your publication runs on your own domain, add it as a normal link block with the address you use, and keep the icon for people who use the Substack address.
What the page does not do
Linkerzz links to your newsletter, but it does not collect email subscribers or run a mailing list. People subscribe on Substack. That keeps your list in one place, which is where you want it.
Keep it fresh without touching your bio
The best part of a link page for a newsletter is that you do not have to touch your profile for each issue. After you publish a new issue, change the text and address of the “latest issue” link and press Update page. The address in your Instagram and TikTok bios stays the same, so you never have to hunt through the profile editor.
If you have not added a link to Instagram yet, here is how to add a link to your Instagram bio. TikTok shows its link option only to some accounts: see how to add a link to your TikTok bio.
See what readers tap
Free pages show how many people visited and which links they tapped, with a daily chart and your three most-tapped links. After a few issues you can see whether people tap your newsletter, your podcast or your shop, and put the winner first.
