I plan to send personalized emails to multiple recipients via AWS SES.
Amazon recommends here to call multiple times the SendEmail method, once for every recipient, instead of just one single call including all recipients at once. However, I'm afraid to hit some API rate limit when calling this method multiple times as they suggest.
They also state here that:
All actions (except for SendEmail, SendRawEmail, and SendTemplatedEmail) are throttled at one request per second.
without specifying the actual limit for the above-mentioned methods, which I haven't been able to find somewhere else.
Does anyone know what is the actual rate limit when calling SendEmail?
You can retrieve this information from the AWS SES dashboard or by using the GetSendQuota API.
The GetSendQuota returns the following:
Number of emails you have sent during the past 24 hours
Sending quota for the current 24-hour period
Maximum send rate
Maximum send rate determines the no. of mails you can send per second.
You can apply for increasing the quota (i.e; both no. of emails you are allowed to send per second and max. send rate).
More info on the same here.
Attaching the screenshot of SES dashboard for reference.

If you're sending bulk notifications to multiple users, the API will
not allow more than 30 messages per second or so. Also note that your
bot will not be able to send more than 20 messages per minute to the
same group.
But it is not clear what is aggregation period for rates to calculate. E.g. would it be acceptable within two seconds to send |0|60| messages which would be still 30 mps?
What are the restrictions for whatsapp Business API Groups.
Can I send messages all the time, or are these messages also restricted by the 24hr session time.
How many groups can I create, could I e.g. create 100 groups, 1 for every person attending some event?
Is there anywhere I can find the pricing for creating these groups?

Can I send any message to any user at any time?
No.
If a user contacts an enterprise, the enterprise can respond with any type of message in the next 24 hours. This type of message is free.
But if the enterprise is contacting a user before the user sends a message or after more than 24 hours have passed, the enterprise can only send a message template. This is a paid notification.
Free-form text messages and media messages will not work outside this 24 hour window. They will result in a failure callback with error 470.
How many messages per second can I send?
The maximum tested outbound message rate is 20 messages per second.

what is the method name ?
From Official API FAQ:
How can I message all of my bot's subscribers at once?
Unfortunately, at this moment we don't have methods for sending bulk messages, e.g. notifications. We may add something along these lines in the future. (...)
Obviously, if you store users chat_id, you can send individual message to all users (I use this method).
Navid wants to send message to all subscribers via bot.
If subscribers are more than 100 persons bot will very slow to sending all messages and may doesn't send messages to all.
Navid's question was how we can send message without this problem?
you can send with curl_multi_exec
Currently, a developer would need to implement a special broadcasting function that would send the message to each active user at the time adding a small delay to avoid hitting the rate limit of 30 messages per second (see https://core.telegram.org/bots/faq#how-can-i-message-all-of-my-bot-39s-subscribers-at-once). This would mean that a very popular bot with say 10K active users cannot give timely notification as the last user would get the message about 5 minutes after the first user.
Here is a feature request to ask to add a method in the Bot API to broadcast a message to all its active users at once. You can upvote this feature request. https://bugs.telegram.org/c/8463
I saw in some articles that the sending limit for gmail is:
*500 per day if we send by website
*100 per day if we send by pop/imap application
My questions are:
1.- The "100 per day" limit its also for an vb net apps that we can make?
2.- How many mails can be send using gmail API (or how many recipients)?
3.- How can I extend the limit with a FREE account?
Regards.
Based on the Usage Limits page of the Gmail API documentation, we have about 1,000,000,000 quota units per day for Daily Usage and 250 units/user/second rate limit.
All method transactions have allocated quota units, if we're specifically looking at the send method (either from drafts/messages), it will cost us 100 units.
I am sending 10,000 emails per day.
So that emails do not end up in the spam, I decided to use the service of Amazon SES.
After testing, I saw that the service Amazon sends 700 emails per 27 minutes. This is a very long time, given the fact that I'm posting every day on 10,000.
All Amazon SES accounts have sending limits. There are two limits: a rate per second and a rate per rolling 24 hour period. You can read more about the sending limits here: http://docs.aws.amazon.com/ses/latest/DeveloperGuide/manage-sending-limits.html
If you exceeded your sending limit then the excess emails would have been rejected.
You can solve this by adjusting your code to respect the throttle rate for your account, or applying for an increased send rate: http://aws.amazon.com/ses/extendedaccessrequest/
