Mautic Email Queue processing,why do Email Sending Time is obviously different from arriving time of receivers Inbox

Hi Joeyk
Finally, I have solved the problem for the issue of email created time

For the Broadcast, if you only send N emails, we can set only cron below.
*/2 * * * * /usr/bin/php /var/www/html/bin/console mautic:broadcasts:send --limit=N >/dev/null 2>&1 #broadcast send
And not need to set below
*/4 * * * * /usr/bin/php /var/www/html/bin/console mautic:emails:send --message-limit=2 >/dev/null 2>&1 #mautic-email-send-cron

Otherwise, they will conflict with each other.

Re the Campaign. we can set below
*/3 * * * * /usr/bin/php /var/www/html/bin/console mautic:campaigns:trigger --campaign-limit=N >/dev/null 2>&1 #mautic-campaigns-trigger-cron.

Now everything works well without setting the queue.
