Newsletter module - when there is a limit on emails per day

[seadhna]

Hi datahell,
a question about how the Newsletter module works: I just discovered that the website server has a very low limit on sending mails: only 100 per day. In the error logs I can see that a mailing that should have gone to 300 was not sent to 200. My question is: does a mailing get sent to users in order? i.e. the 100 successful sends, would they be the first 100 on the list of subsribers? Or is it random?

Update: I was able to confirm via server/host logs that the successful deliveries were the first 100 email addresses in order of date of subscription.

The delivery must be completed within the same day. The next day triggers a new check. If you have a limit of 100 per day and you have more than 100 recipients then only the first 100 will get the email.

How it works:
Newsletter sends X emails where X is the E-mails per run parameter.
It marks down the successes and continues on the next dispatch after time Y, where Y is the Τime gap parameter.
It repeats this until all recipients get the email.
