Just landed here and ready to shape your Substack world? I built an entire second Substack from scratch, and documented the entire process just for you. START HERE. Subscribe and let’s do this together, step-by-step.

This is something that confused me when I first started on Substack. Once a post goes out to your email list, the interface shows an option to edit it — and I thought that meant it would send out again. Spam everyone. Resend the whole thing to their inboxes.

Turns out that’s not what happens at all.

You can edit a post after it’s published without it going back out to anyone’s email. The changes live on your website, in your Substack world, but your subscribers aren’t getting another email about it.

Which means you can absolutely go back and add links, update resources, refine things, without worrying that you’re bothering anyone.

Not only can you edit a post after it’s published — you should. Because your posts aren’t static. They’re living documents. They grow with your body of work.

Here’s what I mean.

You create new resources — a guide, a tool, a post you’ve written since — and you want to add the link back into an earlier piece.

You write new posts that build on older ones — and you want to thread them together so your reader can follow the journey. You can absolutely do that.

You’re building anchor posts — single posts that act as the root system of your whole Substack, linking out to everything else as your archive grows. These are meant to be updated constantly as you add new content.

You’re optimising for SEO — internal linking helps people navigate your world and helps the algorithm understand what’s connected to what. Editing to add those links is genuinely valuable work.

And beyond all that — sometimes you just notice a typo, or a link that’s broken, or something you want to reword. You can fix it. No drama.
