I have been experiencing an unusual burst of adventure and excitement surrounding some of the tools I use. Over the past week and a half I have been trying out Nylas N1 as my daily email client.

Nylas is an open source, extensible email client. It follows the recent software development trend of editors like Sublime Text and Atom. The app focuses on core functionality and relies on the community to add features and visual themes. As a developer you can build the app yourself and use it for free, but you’re locked out of some of the paid functional. So, I signed up for the free trial to give it a full shot.

Nylas has three features I was most interested in:

1. Social Sidebar

When you open an email, the right-hand view pulls up social info for the sender. Including their Twitter picture and other social links. I thought this would be kind of cool and useful. However, I ended up ignoring it entirely.

2. Read Reciepts

Back in the bad old days of Outlook Express (and beyond), you were able to send a “read receipt” to your recipient. IIRC this depended on a proprietary (or non-standard) attachment. The recipient would have to acknowledge the read receipt, then an email would be send back to you in the background and your local copy of OE would process it and produce a “read” checkmark somewhere in the UI. A horribly Kludgy and inefficient process!

Nylas handles read receipts with a server-side process, similar to the way Mail Chimp, etc track opens and clicks. It’s totally seamless.

I found this to be a compelling, albeit creepy feature. My main complain is that the there was no in-app way to disable the notification. Though, seeing someone open your email immediately after sending it, then not hearing back from them (ever!) is also horribly disheartening.

3. Snooze/Send Later

Prior to Nylas, my email client (both on desktop and mobile) has been Google Inbox, prior to that I was using Mailbox. A key feature with both clients was “snooze,” it allows you to basically resend an email to yourself at a later date (or location). My stress level surrounding email decreased 1000% when I started using snooze, I can’t live without it.

I had assumed that Nylas’ snooze feature would sync with Google Inbox’s snooze. Unfortunately they don’t, so Inbox on my phone had no knowledge of the snoozes I’d set in Nylas. Bummer.

Send later is sort of the opposite feature to snooze. It’s a great way to compose an email to a client at midnight and have it automatically send during regular business hours, for example. In the past I’d used Boomerang to send later with gmail. I had been missing the feature since Boomerang is not compatible with Inbox. Nylas’ send later works as advertised. Bonus.

Conclusion

Nylas is good. It’s been a long time since a decent alternative has entered the email client arena. I recommend you give it a try.

Unfortunately, there’s one big issue. The search, it just doesn’t seem to work right. I found myself switching back to inbox to search almost every time.

And there are a few other minor issues that will prevent me from using it.

• It’s slow. I found significant lag between issuing a command and it actually being sent to the server.
• Emails are unsorted. I’ve grown quite accustom to the way inbox groups email by day. Nylas just shows one big ugly list.
• Minor email rendering issues. Sometimes emails appeared to be super wide and off the screen.
• Lack of enhanced email. Google Inbox shows useful snippets for certain types of emails (orders, receipts, newsletters, etc)
• Other minor UI issues. Various parts of the UI seemed a little unrefined. These issues varied somewhat depending on the theme I was trying, leading me to wonder if the theme API is buggy.
• Read Receipts, snooze and send later are all paid features. It’s hard to argue that these features combined are not enough to justify $9/mo and since they rely on Nylas’ servers they couldn’t really exist without paid support.

These are all fairly minor, I know. But for me they add up to a deal breaker.
