"A very neat email client with some interesting features"

What do you like best?

It works spotlessly on my linux machine, was super easy to configure and it has some interesting options: e.g. I can send an email and ask nylas to reminds me to follow up on it if I don't receive any answer within a given time, or I can enable an option that will track who's opening the email I'm sending.

What do you dislike?

The lack of a proper calendar implementation. It would really be nice to:

1/ visualise the emails per day on a calendar

2/ be able to set appointments, meeting, etc and save that since these are things I often need to consult at the same time I'm writting/reading emails.

Recommendations to others considering the product

Don't enable the email opening tracker for all your emails... that will send you a LOT of notifications, use it sparely only for the email where it really matters.

What business problems are you solving with the product? What benefits have you realized?

I just wanted to move away from google's inbox and use the more environmental friendly email provided by lilo.org but to do so effectively I needed a nicer email client than the online solution that lilo provided. Nylas solved that for me and I'm now only using my lilo address thanks to Nylas. As mentioned previously, I also discovered some nice features with Nylas which helped me avoid missing on leads and opportunities 'cause I forgot to send a reminder

"Easy email and calendar integrations"

What do you like best?

Simple API for email syncing and sending, also calendar management and contacts management is easy.

Seamless integrations with Gmail and Outlook and other email providers.

And the best thing about it: they will handle all the problems related to IMAP syncing and bulk email sending for you, so you don't need to worry about it. This alone will save you many months of development time and stress.

What do you dislike?

If your volume is large (syncing thousands of email accounts and sending tens of thousands of emails every day), you will face some issues with 5-10% of your API calls every day, and syncing might be stopped for up to 1h for some email accounts, so you must plan for that when developing your integrations, add redundancies, handle outages and retry when needed.

But you would face those problems anyway (and many, many others) if you were working directly with IMAP, so it's not an unexpected thing. Bulk email sending/syncing is hard.

Also, the tech support is not very helpful/responsive sometimes.

Recommendations to others considering the product

If you want to save time when developing email integration and email syncing, Nylas is the best option on the market right now.

Just be careful when your volume is large or you need lots of fine-grained control over the email syncing.

What business problems are you solving with the product? What benefits have you realized?

- Email account authentication (mostly gmail and outlook)

- Email messages/email box syncing

- Bulk email sending (large volume)

- Google calendar integration

"Unfortunately inmature product"

What do you like best?

Great potential: Single API for connecting to Google/Apple/Microsoft mail/calender/contacts

What do you dislike?

Immature product, i.e. initial sync takes a day for most customers

Does not allow writing to the Apple services

Do not allow you to access all fields (i.e. Gmail object ID needed to open a mail in gmail)

Overselling their capabilities.
