Before I give ACYMAILING super user access, figured I'd try here first. A little concerned about sharing login information over email -- which is not secure.
Using ACYMAILING's paid email service for the first time, to overcome host's 600 per hour email limitation. Getting an error "Send process running in parallel detected". Had it set to 3 batches of 300 emails every 15 minutes. We have 2800 emails to send, and would like to send within an hour or so if possible.
Is this error because of doing 3 batches at a time? what is the purpose of having more than 1 batch?
I had some old cron jobs on my server (from version 5.0) when we sent out the first email, so maybe that was the conflict.
