jacklalley,
But I’m wondering why there is even a mailing list option of this size in EE since sending to that size is forbidden.
EngineHosting is not part of EllisLab but a separate company. This is their policy and not one of ExpressionEngine or any other product of EllisLab. You will have to contact them separately to question the cut-off you experienced.
I think for now I’ll have to figure out batch mode and then we’ll just need to switch to Campaign Monitor.
Batch mode basically means it sends it to what ever batch you set, say 150 then waits a few seconds and sends out another 150 until your whole list has been sent to.
If CM fits your needs then that is fine too. There are actually a lot of add-ons available that will integrate CM with ExpressionEngine.
Does that help?
