So far nothing, everything works as expected. Review collected by and hosted on G2.com.

We've used Nylas APIs in our platform to enable integrations with a number of email service providers to bolster our CRM capabilities. Nylas has worked great for our system, and we've been able to easily use the services for our needs. In particular, wanted to call out Nylas' exceptional support. After running into an unexpected, urgent issue related to a Google integration, Chris from Nylas' support team brought his went above and beyond to help us resolve. He was professional, competent, and sensitive to our timeline - and therefore very responsive. Very appreciative of the reliable support from Nylas, thank you!

No notable downsides! Happy with the product Review collected by and hosted on G2.com.

The single point of integration for email Review collected by and hosted on G2.com.

Slow response times on webhook triggers. Review collected by and hosted on G2.com.

Easy to implement and Nylas maintains all the backend connections to various providers so we don't have to. Review collected by and hosted on G2.com.

Google verification is expensive, but that is really a Google issue, not a Nylas issue. Review collected by and hosted on G2.com.

The fact their documentations are super thorough and explanatory is amazing, on top of that that the product makes it seamless to integrate with main Google APIs without having to go through the hassle of the entire Google infrastructure and chaos is key. Review collected by and hosted on G2.com.

We haven't stumbled upon any main pitfalls yet - it delivered on what was promised - perhaps integrating with more Google APIs such as Sheets / Docs, etc. Review collected by and hosted on G2.com.

Easy way of supporting multiple email providers without having to build a specific integration for each one Review collected by and hosted on G2.com.

- Worst support I've experienced in years. They make you debug their own API and you have to hand them in a report to try to make the case for them to fix their issues

- Can be down hours at a time without any communication

- No concept of support outside of PST hours - not even when their API is down

- Ignore core bugs that render entire parts of their api useless for months

- Obscure pricing

- All in all I'm not happy with the decision of adding Nylas to our stack. Now we are stuck with them and they make it rather hard to switch out (e.g. not exposing real message ids, only Nylas message ids) Review collected by and hosted on G2.com.

Simple to setup & a great developer experience. We've been able to support our large enterprise customers effectively with Nylas for years. Review collected by and hosted on G2.com.

For our use case, there is not much to dislike. There are some times that we'd like certain filters added to the APIs, but nothing big enough that has hindered us from providing our product to our users. Review collected by and hosted on G2.com.

Mail API independence.

Easy to use API.

Friendly customer service.

Over time issues do eventually get resolved.

A lot of other features available like calendar integration (though we haven't implemented this in our own software yet) Review collected by and hosted on G2.com.

Show stopping problems are ignored for months on end. When the problems on their side are realized, no accountability is taken and no real apologies given.

They ask that you troubleshoot the API on your own and return with detailed logs and ways to reproduce. Even when you do this and they bring technical people onto the call, they won't know what to do about it or even understand the logs. Then they will insist that they don't see the errors in their own logs and suggest that it might not be happening, despite the logs provided clearly indicating that it is.

After going back and forth with them regarding problems they'll begrudgingly admit that at some point it became a known problem and that they are working to resolve it. This usually means it'll be a couple more weeks before the problem goes away.

If you're having problem with a specific group of customers like Office 365. They'll expect you to keep ferrying questions to them and having them try things despite the customer getting more and more frustrated. You'd think that they'd have some sample accounts with some integration tests for things like this. At some point they should realize that our clients are already frustrated with poor service and that we don't want to subject them to continuous troubleshooting. These people have jobs of their own and shouldn't be bothered with trying to assist Nylas in fixing issues for extended periods of time.

The documentation is usually broken. When you helpfully inform them of this they'll helpfully inform you to create an account and fix it yourself. I seriously don't have all day nor the expertise to be fixing Nylas's documentation. Perhaps the documentation is so broken because they have customers making changes without enough oversight.

Their response time for fixing issues has historically been so bad that we just build fixes and queuing systems around their service so that it just periodically tries again. Expect to do this if you go with them. You may even need to implement backup SMTP settings for when the service is failing on sending for time sensitive emails that need to go out.

When you connect up an email account they don't really give you options for how you want it handled. So if you've got a webhook in place, expect it to start receiving ancient email from that account for a long time... even if you don't want or need that data.

All of these problems being said... several of the issues we've faced have been resolved or you can work around them. A new customer signing up will hopefully not have as bad of an experience as we've had. We were with them before they switched to using APIs (when they were using IMAP and SMTP only). When they made that transition, that's when things seemed to get really bad for several months. Review collected by and hosted on G2.com.

It's really easy to get started with connecting niche email accounts (e.g. IMAP, Zoho, Hosted Exchange) all while having a familiar API to work with. Their support is reliable too Review collected by and hosted on G2.com.

Early days of Nylas were a bit rough but they've gotten better over time. Some iffy things you may run into:

1. You will get double charged for accounts if they change email services or if your customer "accidentally" logs in

2. It's tough to know the configuration your customer used. (e.g. I'd like to know what IMAP address they used)

3. Billing isn't transparent enough Review collected by and hosted on G2.com.
