Bulk Email Function

I know this has been discussed in the past.

Is there any idea when bulk email sending will be implemented?

Sending invoices and/or statements to 300 customers is a bit cumbersome.

Continuing the discussion from Bulk email of statements:

Thank you for a great program.

What’s the criteria for sending the invoices? Is it something like “all invoices generated in the last 24 hours should be emailed”?
