Bulk email not being delivered

[Tony1967]

I regularly send emails to a large c500 group. I split into groups of 45 people all bcc and my own email in the To field so about a dozen messages. Usually has an excel spreadsheet attached. No problems other than leaving 30 minutes after the first half dozen before doing the rest.

Today sent them out so 6 then 6 messages but nothing come back and no one has received. Not had any reject message or anything.

Have managed to successfully send to two people on one email since.

Any ideas?

I suggest you use a commercial email service rather than a domestic service not intended for that sort of operation.

I had to set up something very similar for a client some years back.  The way around it used to be to run a script, so you could send out a single email at a time (so not BCC).  I'm not aware of an easy way to do this anymore, other than has already been mentioned by @licquorice to use a commercial email service!
