We're working on building a plugin index that makes it super easy to add them to Nylas Mail. For now, check out the list below! (Feel free to submit a PR if you build a plugin and want it featured here.)
Great starting points for creating your own plugins!
- Translate—Works with 10 languages
- Quick Replies—Send emails faster with templates
- Emoji Keyboard—Insert emoji by typing a colon (:) followed by the name of an emoji symbol
- GitHub Sidebar Info
- View on GitHub
- Personal Level Indicators

Note these are not tested or officially supported by Nylas, but we still think they are really cool! If you find bugs with them, please open GitHub issues on their individual project pages, not the Nylas Mail (N1) repo page. Thanks!
- Jiffy—Insert animated GIFs
- Squirt Speed Reader
- Website Launcher—Opens a URL in separate window
- In Development: Cypher (PGP Encryption)

When you install packages, they're moved to ~/.nylas-mail/packages, and Nylas Mail runs apm install on the command line to fetch dependencies listed in the package's package.json
Building the docs
Plugin SDK docs are available at https://nylas.github.io/nylas-mail/. Here's how you build them:
Until my patch gets merged, docs need to be built manually using mg's fork.
git clone firstname.lastname@example.org:grinich/gitbook.git cd nylas-mail ./node_modules/.bin/gitbook alias ../gitbook latest
Then to actually build the docs:
script/grunt docs ./node_modules/.bin/gitbook --gitbook=latest build . ./_docs_output --log=debug --debug rm -r docs_src/classes
If you want to preview the docs:
pushd ./_docs_output; python -m SimpleHTTPServer; popd
Just want to publish everything? There's a helper script that does it for you:
You can configure Nylas Mail in a few ways—for instance, pointing it to your self-hosted instance of the sync engine or changing the interface zoom level. Learn more about how.
