I'd like to send a emails to a large number of account and contacts when they are campaign members.
I know it is possible to do this via the standard sfdc interface, but it is unclear how many emails can be sent per day like this. I've read that the limit is 1000 "external addresses", does it apply here too? Must the emails be divided in batches (I've read that one must select 500 campagin members at a time)?
Also, if I want to use APEX and use the method: setTargetObjectIds, will this also count toward the 1000 email per fay limits?
Thank you very much for your assistance, T.
