You can define how many emails Mailster sends in a certain period so you can respect your provider’s limits.
Depending on your server setting Mailster can send approx 1-2 emails per second. Some of our customers are able to send 12 mails per second – which are approx 43.000 within one hour!
Usually approx. 2-3 emails per second are considered average and if your list is below 5.000 subscribers you’re all good.
Please contact your delivery provider on how many emails you can send in a certain timeframe.
With Mailster you can also try to send your campaigns as fast as possible.
Do not send too many emails at once!
Sending more than 200 at once can cause server timeouts! You should decrease the cron interval!
