Hello,

I have created a Nintex workflow to send bulk notification emails. 

The email IDs will be read from a list and stored in  a collection variable. I am placing this collection variable in BCC field to send the reminder emails. My question:

1. How many values can a collection variable store at max? (There might be almost 3000 values to be stored in my case)

2. How many emails can be sent out at max using 'send notification'? (I have to send a single email to these 3000 email IDs keeping the collection variable in BCC)
