Batch email sales invoices

I have been looking through previous topics and requests, I see that there has been requests for batch emails - one of the repliers said that it would be great to be able to email all clients at once because he/she has 40… But I cant seem to get the answer to these requests.
Well I have 156 clients for who I have created recurring sales invoices, but to send out 156 invoices and 156 statements separately takes forever!

Where do we vote for a batch email function?

You don’t. Development priorities are not based on user surveys, votes, or polls. The developer is the sole determiner of when or if new features are added.

I apologize, I saw on the other requests that they said that not enough people voted for this option, so I thought it would be wise to ask

Years ago, there was a voting option (by clicking a button) for suggestions in the ideas category. But with more than 260 ideas currently in the list, that became pointless.
