Readwise Reader, Zotero or Email2Obsidian: what each one is for

The short answer

Zotero is for references. Reader is for reading. Email2Obsidian is for your inbox. Choose by the job you need done, not by brand, and don't be surprised if the answer is "more than one."

• Zotero

  Best for: Collecting papers, annotating PDFs and inserting citations into your writing.

  Watch out for: It isn't an email inbox.

• Readwise Reader

  Best for: Reading and highlighting a steady flow of articles and newsletters, then syncing highlights to Obsidian.

  Watch out for: It's a paid subscription, and full-text export covers Library items only.

• Email2Obsidian

  Best for: Saving specific emails, with their attachments, as notes in your vault.

  Watch out for: No reading interface, no highlights, and no newsletter subscriptions.

Zotero: references, PDFs and citations

At the time of writing (November 2026), Zotero is a free, open-source tool for collecting, organizing, annotating, citing and sharing research, built by a nonprofit. It plugs into Word, LibreOffice and Google Docs for citations. A free account includes 300 MB of sync storage, and you can buy more if you need it.

Lots of Obsidian users pair the two through community plugins like Zotero Integration or ZotLit, which turn Zotero items and annotations into literature notes.

What Zotero doesn't do is act as an inbox. It won't turn your supervisor's feedback email, a journal alert, or a conference confirmation into a note in your vault.

Readwise Reader: reading, highlighting, newsletters

Reader gives you two email addresses. The @library.readwise.io address is for one-off documents. The @feed.readwise.io address is for newsletter subscriptions and auto-forwarding rules. You can subscribe to newsletters with the feed address directly, and Reader handles Gmail's forwarding confirmation for you.

On the Obsidian side, the Readwise export syncs your highlights. Turn on "Export All Reader Documents" and it also adds a full-text file for each document, for Library items only, not Feed items.

Reader is a paid subscription. See Readwise's pricing page for current plans.

Email2Obsidian: emails you choose, as notes

You forward or send an email to your private address, and our community plugin saves it in your vault. The subject becomes the title, the body keeps its formatting, and attachments are attached and embedded, up to 25 MB. Add #tags to the end of the subject ("Ch3 feedback from Dr. Lee #thesis #ch3") and they become note tags. On Pro, @@VaultName picks the vault. You choose the destination folder and template in the plugin settings.

It's deliberately narrow. Email2Obsidian doesn't summarize, doesn't pull citation metadata, and doesn't give you a reading interface. You read and highlight in Obsidian, the same as any other note.

Side-by-side by job

The overlap: newsletters

This is the one place the tools genuinely cross over, so it's worth being straight about it.

Reader is built for newsletters. You can subscribe its feed address to a newsletter directly, and every issue shows up ready to read and highlight.

Email2Obsidian works the other way around. You forward the issues worth keeping. You can't subscribe your ingest address to a newsletter, because we only accept mail that comes from you, and automatic Gmail forwarding isn't supported today either.

So here's the honest call. If you read a lot of newsletters and highlight as you go, Reader is the better tool. If you'd rather keep the three issues a month that really matter as files in your vault, Email2Obsidian is simpler. More on that in save the newsletters worth keeping.

Recommended stacks

PhD student or researcher

Zotero for references, plus Email2Obsidian for everything that arrives by email: supervisor feedback with the marked-up PDF attached, the alerts worth reading properly, and ideas you email yourself from your phone with #thesis. See email capture for researchers and PhD students.

Reading-heavy PKM user

Reader for reading, the Readwise export for highlights, and Email2Obsidian for the email that isn't reading at all: receipts, follow-ups, confirmations.

Student on a budget

Zotero (free) plus Email2Obsidian Free or Starter. There's no student discount, but Starter is $2.49/month for 300 emails, and the Free plan gives you 10 emails to see whether it fits. Here's more on email to Obsidian for students.

When you don't need Email2Obsidian

Plenty of people don't, and that's fine. Skip it if:

• Your only email-to-vault need is newsletters, and you want to highlight them. Reader does that job better.
• Your research capture is all papers and PDFs you find yourself. Zotero covers it.
• You rarely get email worth keeping. Copy and paste the occasional one. Really.
