Setup guide

Get readleaf working in 3 minutes.

Select your device below. The setup takes about 3 minutes and you only do it once. The key step is telling Amazon (or Kobo) that readleaf is allowed to send documents to your device.

1
Find your Kindle email address
Every Kindle has a unique @kindle.com address that Amazon uses to deliver documents. Go to your Amazon account to find it:
Open Amazon Document Settings →
Under Personal Document Settings, you'll see your address — it looks like:
yourname_XXXXXX@kindle.com
Copy it — you'll need it in step 3.
2
Approve send@readleaf.io as a trusted sender
Amazon only delivers documents from email addresses you've approved. On the same Personal Document Settings page, scroll down to "Approved Personal Document Email List" and add:
send@readleaf.io
⚠️ This step is required. If you skip it, articles will be sent but won't arrive on your Kindle — Amazon silently rejects documents from unapproved senders.
3
Install the readleaf extension
Install readleaf from the Chrome Web Store, then click the leaf icon in your toolbar. Enter your @kindle.com address when prompted.
Get the Chrome extension →
4
Send your first article
Navigate to any article you want to read. Click the readleaf icon in your Chrome toolbar, then click Send to Kindle. Your article should appear on your Kindle within 30 seconds.
Make sure your Kindle is connected to Wi-Fi. Articles deliver over the internet, not USB.
5
Set up newsletter forwarding (Reader plan)
Reader plan members get a unique readleaf email address for newsletter forwarding. Find yours in your dashboard under Account settings.
💡 We recommend subscribing to newsletters with your personal email address — that way you stay in control of your subscriptions and can unsubscribe directly with the sender anytime.
6
Set up Gmail forwarding
Once you have your readleaf address, set up a forwarding filter in Gmail:
1. In Gmail, go to Settings → See all settings → Filters and Blocked Addresses → Create a new filter
2. In the From field, enter the newsletter sender's email (e.g. newsletter@nytimes.com)
3. Click Create filter, then check Forward it to and enter your readleaf address
4. Click Create filter — done. Every future email from that sender will automatically forward to your Kindle.
To stop a newsletter from going to your Kindle, just delete the Gmail filter or unsubscribe from the newsletter directly.

1
Set up Send to Kobo
Kobo devices receive documents via a Dropbox integration called "Send to Kobo." On your Kobo device, go to:
Settings → Accounts → Send to Kobo
Connect your Dropbox account. Kobo will create a special folder called "Send to Kobo" in your Dropbox.
Don't have Dropbox? Create a free account at dropbox.com — the free tier is all you need.
2
Get your Dropbox email address
Dropbox has an email-to-Dropbox feature that lets you send files directly to your Dropbox folder via email. To find your unique Dropbox email address:
Go to dropbox.com → look for your email-to-Dropbox address, or use a service like send.to which bridges email delivery to Kobo.
💡 Alternatively, if you use Calibre, you can configure an email address there to receive EPUBs and sync to your Kobo via USB or Wi-Fi.
3
Install readleaf and enter your delivery address
Install the readleaf Chrome extension, click the leaf icon, and enter whatever email address delivers documents to your Kobo — whether that's a Dropbox email address or a Calibre address.
Get the Chrome extension →
4
Send your first article
Navigate to any article you want to read. Click the readleaf icon, and hit Send. The EPUB will arrive in your Dropbox Send to Kobo folder and sync to your device next time it connects to Wi-Fi.
5
Set up newsletter forwarding (Reader plan)
Reader plan members get a unique readleaf email address for newsletter forwarding. Find yours in your dashboard under Account settings.
💡 We recommend subscribing to newsletters with your personal email address — that way you stay in control of your subscriptions and can unsubscribe directly with the sender anytime.
6
Set up Gmail forwarding
Once you have your readleaf address, set up a forwarding filter in Gmail:
1. In Gmail, go to Settings → See all settings → Filters and Blocked Addresses → Create a new filter
2. In the From field, enter the newsletter sender's email (e.g. newsletter@nytimes.com)
3. Click Create filter, then check Forward it to and enter your readleaf address
4. Click Create filter — done. Every future email from that sender will automatically forward to your Kindle.
To stop a newsletter from going to your Kindle, just delete the Gmail filter or unsubscribe from the newsletter directly.

Troubleshooting

Article sent successfully but nothing arrived on my Kindle

Almost always caused by a missing approved sender. Go back to Amazon Personal Document Settings and confirm send@readleaf.io is in your Approved Personal Document Email List. Also make sure your Kindle is connected to Wi-Fi.

The extension says "This page doesn't contain enough readable content"

readleaf works best with news articles, blog posts, and long-form writing. It won't work on YouTube videos, social media pages, product pages, or login walls. Try it on a full article page rather than a homepage or feed.

The article arrived but looks garbled or has missing images

Some sites use unusual formatting that doesn't convert cleanly to EPUB. Images embedded in articles may not transfer. The article text should always be readable — if it's completely garbled, email us at hello@readleaf.io with the URL and we'll investigate.

I entered the wrong Kindle address. How do I change it?

Click the readleaf icon in Chrome, then click the small "change" link next to your email address at the bottom of the popup. This will let you enter a new address.
