Not able to understand AWS Workmail sending algorithm.

0

We were using Amazon WorkMail yesterday, where after sending 400 emails my emails started getting deferred or blocked. According to AWS Workmail, document Limits are 1000 Emails/ per organization. ( Please don't provide the AWS Workmail documentation link I already have that but it's not clear)

Brief Explanation of our sending - We have one organization that is having 4 users we use each user to send 200 emails/ each user. After we sent 400 emails using 2 users ( 200 each/ user) when we tried sending emails from 3rd user it's not get delivered. So can anyone enlighten me on what the issue is? And please explain if you can because AWS documentation on WorkMail isn't much clear. Need Urgent help so I can finally send important updates to our clients. Would really be glad if someone can help me.

Hi,

I'm sorry to hear you're experiencing problems with sending mail. According to the WorkMail documentation these are the limits:

"100,000 recipients external to the organization, with no hard quota on recipients internal to the organization" Documentation

I took a look at your account and it seems that it has been limited for violating the WorkMail policies. Please check your personal health dashboard for more information and what steps to take to resolve this.

Kind regards, Robin

    Ik that they limited my sending I message support regarding that, but I didn't get why I am not able to send more emails than 400 why did it get stopped after that? You saying 100,000 recipients but we are not even able to send 1000 emails.

    Hi Tom,

    I'm sorry my message was not 100% clear. A restriction has been placed on your account for violating the terms of service. This is limiting the number of mails you can send. To resolve that you will need to follow the instructions from the case on your personal health dashboard.

Hi, are your email recipients well distributed across DNS domains or do you tend to group them per domain? If latter is true, the AWS SES smtp servers may try to send all those messages in a short period of time with same origin, triggering soft bouncing by the recipients servers and corresponding throttling / deferring for you.

So, I would first check that. It it's true, more "randomness" in each packet of 200 may accelerate.

Generally speaking, you should try to identity the origin of your details: stage1 with Amazon WorkMail, stage2 AWS SES or stage3 recipient side to find best solution for your use case faster.

Hope it helps! DIdier

    Thanks, Didier for your response, We use one domain for sending to our recipients.
