A portfolio company of ours, GrowthGenius, has used Nylas since 2019. Management spoke highly of it, saying it helped them handle email integration in GG's lead gen platform.

A few points that stood out:

- flexibility and ease of integration.

- API documentation is clear and well-structured.

- Email synchronization (email data, contacts, and calendars across different email providers) Review collected by and hosted on G2.com.

Nothing to complain about, that's worth noting. CS team is pretty solid, so it makes up for any shortcomings. Review collected by and hosted on G2.com.

Nylas offers a comprehensive set of features, allowing to access and interact with email data, send and receive messages, manage calendars and events, and handle contacts.

So using Nylas we easely implemented 2-way sync of data with our crm system. Review collected by and hosted on G2.com.

Nothing.

All issue our team faced during integration Nylas - was solved quickly.

Even when we were found some gaps in a sync proces Nylas team provided updates in a short terms. Support team worked well, provide a lot of effort to help us, provided a lot of details and clarifications. Review collected by and hosted on G2.com.

The universal nature of the email endpoints and the ability to quickly setup and launch. Really helped us throught the Google Audit process quick and easily Review collected by and hosted on G2.com.

We had some breaking system changes. Well communicated but never ideal to change your architecture Review collected by and hosted on G2.com.

The API is easy to integrate with. When it works, it's good. Review collected by and hosted on G2.com.

The platform is HIGHLY unstable and filled with bugs. We've spent weeks writing code to workaround their quirks. The customer support team is not very responsive, they spend so much time asking you to gather evidence of the issues and once you gather them, they say they will create a ticket and never respond with resolution of the bug. We have had critical bugs that have not been resolved in months. Avoid this platform at all costs. Review collected by and hosted on G2.com.

We have been using Nylas for over 9 months now. The API was stable and reliable. Developer documentation is amazing, everything is covered in detail with both text descriptions and code examples. The SDK was also very nice. I would also like to highly recommend Alex Gremer and Maggie Harwood for their help during the process. They handled everything professionally and with great care, and excellent communication at all times. Overall, best customer experience by far! Review collected by and hosted on G2.com.

The biggest issues that we've had along the process were tied with Google verification and not with Nylas. Unfortunately, that's the part of the process that Google requires. Review collected by and hosted on G2.com.

The technology made integrsting an email client into our app feasible without excessive dev time. Review collected by and hosted on G2.com.

The tech is still evolving. There are some feature holes but they are being addressed. Review collected by and hosted on G2.com.

Google Calendar integration was easy to set up. Review collected by and hosted on G2.com.

Nylas does not support OAuth for Outlook accounts and expects customers to build basic authorization. This is a no-go from a security pov for us. However, the same was not mentioned during the sales cycle, rather we were promised that all functionalities are available for both Google and Outlook.

It's been 3 months (at the point of writing this review) since we raised this issue with their team. In 3 months they have not been able to even mention which quarter I can expect this functionality to be available. The support team is extremely slow to reply and our emails have gone unanswered for weeks at times. Review collected by and hosted on G2.com.

1.) Great documentation

2.) Excellent scaled cost

3.) Easy to implement Review collected by and hosted on G2.com.

I'd like there to be more granular control of specific calendar apis like Google. For example, I'd like to be able to control the calendar entry color Review collected by and hosted on G2.com.

We used this tool for two years, its besides the poor microsoft connection really a good solution to google imap. Currently, we are using a platform (**gun) for all our e-mails, therefore we canceled Nylas. Review collected by and hosted on G2.com.

Currently, we are using a platform (**gun) for all our e-mails, therefore we canceled Nylas. First, the said we had a year contract and they aren't possible to cancel directly. I asked for a signed contract to conclude if this was a month/year payment, they backed down and it was a monthly payment with 1 month cancellation period. I've paid one month extra, but it is unclear what kind of contract you have... and the support team is not that friendly and cooperative. I wish them all the luck. Hopefully this point will be improved in the future for new customers! Review collected by and hosted on G2.com.

It's an integral part of our ATS/CRM and a key feature for our users to be able to consult previous communications with their clients and contacts.

Great support and communication. Allowing us to integrate services as we need them. Follow-up by Customer Success Manager, they care about their users. The dashboard has been improving over the years.

We had to move away from a service that was shutting down. The transition was smooth without any issues. We're looking forward to using additional services besides the email synchronization we currently use. Review collected by and hosted on G2.com.

While there are SDK's for certain programming languages, there's one missing for PHP unfortunately.

The dashboard could use some extra functionality to troubleshoot issues ( API calls through the web interface,...).

Some issues are not seen as important and put as low priority. Review collected by and hosted on G2.com.
