Hey there,
I have a problem with Gmail pack.
I’ve just purchased the pro plan to have unlimited possibility to send Gmail from Coda button. And now that I want to do it I still have this message :
“Gmail::SendEmail failed - Couldn’t take action in Gmail: too many requests sent”
How can I fix this ? Pretty blocking for us 
Thanks
Can you share a screenshot of your settings for the button and any formulas used? Also, there are Gmail sending limits, but those are usually around 500 to 1,000 per day.
