Batch delivery for large mailings
Created by: mfb
Can this extension do batch mail delivery to Sparkpost? From a quick look at the code, it didn't seem like it, but I could have missed something.
Use case: I am sending a mailing to 500,000 recipients, and I'd like the whole sending and delivery process to be as fast as possible, maybe an hour or so.
The solution, if you're using SMTP, is to open up a pool of concurrent connections, sending to perhaps thousands of recipients with each connection before closing it. Or if you're using HTTPS, send as many messages as possible with each request, perhaps using a pool of parallel requests.
