Hi I have a list of emails (say 500) stored as pages. If I wanted to bulk email this group could I just loop through these pages with <cms:pages> and send with <cms:send_mail> ? Is there any disadvantage to this method?
Depending on your server's configuration, you could risk overwhelming the resources by trying to push through all the mails in a singe go.
Preferred way would be to take the 'staggered' approach as done by the CSV importer -
I think you can modify it to send emails in batches of, say, 20 per loop.
Hope this helps.
