Max number of email addresses you can send to (bcc)

[#1]

I've got a mailing list of around 150 membership addresses.
Can I send a mass mailing out to all these (I'd use the bcc rule) - or is that likely to get into trouble at the Pnet server?
Would I need to break this number down or can you cope with 150?
Thanks

Hi newinvention,
You should be fine with 150 emails, there's rate limits in place to help against spam but 150 should get through alright without taking too long

Why not try creating a mail merge instead?
