I'm currently writing a basic newsletter mailer with Swift. I have everything working in a test environment, with just a bunch of e-mail addresses. This all works flawlessly.
Now in the actual application I will be sending to around 2000 e-mail addresses. Though I understand the basics are the same, I have a few questions about the implications of scaling it up:
- How long will it take to send a newsletter to 2000 addresses? Should I change my PHP-execution time, or will the defaults be sufficient?
- Is it necessary to create batches from the database myself and pausing between them myself? Or is this an acceptable number to be handled in one go?
- Any tips for best practices here?
Off course I'd like my application to work right on, as there isn't much room for testing it, using peoples real addresses
Thanks in advance for any tips!
Cheers, Michiel
