FluentCRM email sending speed
Hello all,
Looking for some insights, tips etc.
We have around 70k contacts, which we send about 500k emails a month.
I have noticed with the new version things getting better but i rarely get above 500 sent emails per minute in my campaigns.
the setting in fluentcrm for max email per second is set to 25
i have it connected via FluentSMTP to Amazon which has 60mails per second so this is not the bottleneck.
I have a seperate server on Cloudways for FluentCRM, 4c/8GB but it is BASIC (shared cpu)
I have noticed that in the new version aprox 5 min before the scheduled campaign fluent start to "proccess" emails, coudn't find in the documentation, what this acctually does.
looking at htop while the campaign is sendig it does look that the cpu is the bottleneck, should i go for dedicated cpu or more cores?
tnx. 😀
Email ending speed depends on many factor but mainly between your SMTP/sending API round trip as email are being sent ony by one. If you want to speed it up here is the technica doc: https://developers.fluentcrm.com/modules/email-sending-speed.html
Shahjahan Jewel is multi threading still present in version 3+ ? there is no advanced in settings anymore
alo another note, processing before sending is started fixed 5 min before schedule sending time? i've had campaigns with 5k receipients processed in this time but today campaign with 25k emails, was processing well beyond scheduled time for the campaign, so sending started about 10 mins late.
while in the sending stage, i've noticed with smaller campaigns processing mails to be around 60-80 but today with this 25k campaigns is going well over 300 processing, it almost seems that the server resources are beeing used better with this campaign
