Error encountered while sending using Gmail API due to Rate Limit Exceeded

This error comes directly from Google and occurs when the provider rate limit has been reached. You can look more into Google's daily limits here.

We recommend doing an exponential back-off before retrying when you get this error from Nylas.  

If the error occurs frequently, consider reaching out to Google to request a raise in the quota of your Google Project. For more information about how to do so, please see: https://cloud.google.com/docs/quota
