I've actually not used batch sending I always thought the small
batches and the delay between batches added too much time to the
sending process Although I just did the math and it's not that big
of a deal if I were to set the max of 180 between batches and one sec
between batches then that would add three minutes to the list of 31k
If I do a batch of 100 and a sec between it add a little over 5mins

Per your suggestion that you always use it, I'll try it on the next
blast 5mins is not important

Batch vs non-Batch and how many to send per batch?

We were doing 1 per batch, and then a 0 001 wait (basically as fast
as the server can go), but is there any downsize in sending more
than 1 email per batch?

Was thinking that maybe more messages per batch might increase SPAM
ratings (if they are sent as BCCs or similar) or can we do say 50
per batch, and then a 1 second rate which sounds sensible?

I really don't think so I kind of think of batch settings primarily
to slow things down for hosts that only allow you to send < 500
messages/hour The problem you'd probably come across if you're
trying to send very very very fast is multiple messages to the same
service too fast If you send, say Yahoo! Mail 50 messages in a
course of a few seconds, they get a little suspicious

Dada Mail won't be sorting email addresses by domain when it mass
sends out, so it shouldn't be a major cause of alarm The actual
time overhead of sending 50 messages is really going to discount
much of the possibility that you'll hit one domain too much

I somewhat suggest keeping batch sending on, as I don't test without
it! But the whole batch sending stuff will add overhead I'd be
surprised if you didn't get a few percent increase in speed by
turning it off completely

Hi John

Email is fairly light as we host all the images externally rather
than including them in the email, so just HTML and PLAIN TEXT
versions within the send

Wow, that's really great Curious, how large in kb is the email
you sent when you got that rate?

On a shared hosting server here and am fine with the speed I'm
getting My list is 31,661 A small 17kb piece was sent at 14,071 per hour A larger 160kb piece was sent at 6347 per hour This speed will vary a little depending on day of the week and
time of day it's sending

Running Pro 3 04, using sendmail, but no batch sending MySQL for
data

Still having the first one bog down It took well over 7 minutes
to send a sample email to myself for testing:

Your mailing has reached: 1 e-mail address(es) Mailing Started: 09/09/2009 15:14:23 Mailing Ended: 09/09/2009 15:22:19 Total Mailing Time: 7 minutes, 56 seconds

After the first one goes through, then speed picks up
