You will have to wait 12-24h in order to get an answer to your issue. Unless you are a paid customer. Review collected by and hosted on G2.com.

Our integration was super quick for something so complicated as email integration. The support docs were very helpful and easy to understand. Review collected by and hosted on G2.com.

Support response times have some room to improve. Review collected by and hosted on G2.com.

Quick to integrate multiple email domains into our solutions. Review collected by and hosted on G2.com.

None so far. Very easy to use and support when needed has been great. Review collected by and hosted on G2.com.

Very developer friendly with lots of security certifications to give you peace of mind. Good customer service as well. Review collected by and hosted on G2.com.

Some of the technical documentation can be a little unclear, and sometimes an API call can take a long time but it's not clear why. Review collected by and hosted on G2.com.

Nylas has enabled our small engineering team to bring e-mail features into our product much more quickly than we would have been able to do on our own. In addition to providing a uniform interface across different email platforms, the documentation is full of helpful guidance and caveats that helped us cut down on the engineering time needed to build production worthy features on top of e-mail. Also, the support team has been truly amazing, they are both responsive to our questions and proactive about reviewing our integration and reaching out to us when new developments can help us with our specific use cases. Also, the pricing is transparent and easy to get started with. Review collected by and hosted on G2.com.

There is no ability to limit the scope of e-mail sync, e.g. to exclude messages that are entirely from and to an internal domain or specific addresses, so even though Nylas has achieved SOC II, some of our customers are unwilling to have sensitive internal e-mail synced to any third party (be it us or our providers). The API performance is a bit inconsistent in terms of request latency for viewing email messages/threads. The only other tricky spot is that some provisioning actions must be taken through the dashboard with no API support. A full terraform provider would be great to integrate with the rest of our infrastructure as code deployments. Review collected by and hosted on G2.com.

Nylas makes it easy to add email functionality in your product. Their newly assigned Customer Success Rep is Top Notch! Review collected by and hosted on G2.com.

Other than some production issues would be good to have a few more features in the API (like replay etc..) Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

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.

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. Review collected by and hosted on G2.com.

Great potential: Single API for connecting to Google/Apple/Microsoft mail/calender/contacts Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

Simplicity of usage and connectivity. Can able to connect to any mail box without much hussle. Review collected by and hosted on G2.com.
