I am using Mautic 4.2 and Amazon SES which has currently 14/sec max. send rate. However, I am not being able to send more than 7/sec of emails using queue. I have to be ready for future which might need about 300/sec. I have checked that infrastructure is not a problem as I cant see spikes on CPU …

Hi, check this forum post: [image] Matching SES send rate General Discussion I’m wondering if Mautic automatically matches SES send rate? Or I should follow OPs settings? I also have 14 emails / sec limit and would like to know if I should do something in mautic to match t…

Thanks @joeyk for reply. I looked into the post you referred but as mentioned in Optimize part, I try to send 790 with below command but I find that Mautic is not able to send 790 per minute, it just sends 500 per minute app/console mautic:emails:send --message-limit=790 --time-limit=60 Can you …

The reason: Your server is too slow. You’d need to investigate the bottle neck. (DB, memory, CPU?) At the same time I would be cautions with sending so fast. If you exceed the limit, you lose emails. Joey

Thanks for getting back to me We already checked our server CPU, memory and network which is ok. As long as we are close to SES max send rate, we don’t worry sending to fast. Can you please suggest anything else that is delaying sending emails? Is multithread with locks only way? Have a good day …

Server CPU /memory showing OK values when you run HTOP doesn’t mean that you fully utilize it. You need to tweak your DB and PHP settings in a way to speed up send. Mautic 5 will speed up email sending by 3,5x. I’s wait for that couple of months. Joey

Thanks @joeyk for replying. I agree with you that we need to tweak our PHP setting and DB. Can you please let me know what is setting I need to look into? Excited for new release already. Have a great day

Hi, I can’t give you optimization advice as I don’t know your environment. I suggest you post a job in the forums. I hope someone can solve it. Joey

Hi @joeyk I applied multi-threading to send emails and got success to achieve a faster send rate like with one thread is 10/sec and I have applied 5 threads which gives 50/sec throughput. However, I have found that there is an issue with duplicates. Same email gets sent multiple times when multipl…

Hi, try to set limits according to your cron cycle. And run this command every minute with a time expiry of 45 sec.

Thanks @joeyk for your advice. I set time limit of 45 sec and message limit of 300 but there are still duplicate emails in the inbox. Can you please review below command? Thanks, appreciate your help /bin/php /var/www/html/mautic/bin/console mautic:emails:send --lock_mode=flock --lock-name=“1” --me…
