If I send a message to my own phone, it gets received properly. If I send it to my wife or son's phone, the message does not get received. Despite this, the SNS dashboard says that the messages were properly sent. I hope I'm missing something, but at this point, I don't feel like I can use SNS for customer facing apps if all the feedback I get says it worked fine, but I can't guarantee that the users actually receive a text. This is the first time I've used SNS in this way. Is this expected behavior or am I maybe missing something?

Prerequisites
I use AWS SES to send an email with event publishing to track the delivery status.
Problem
I'm looking for an event to make sure that an email is successfully sent to the end-user.
Description
Following AWS documentation, this type is suitable:
Deliveries – Amazon SES successfully delivered the email to the
recipient's mail server.
However, this event I get also in case Hard bounces.
For example, email status flow is:
Sends -> Deliveries - in case of successfull delivery
Sends -> Deliveries -> Hard bounces - in case I provide invalid recipient name, e.g. invalid#domain.com or 1234567890#domain.com
I don't expect Hard bounces after Deliveries.
If this behavior is correct then I need some additional event for sure success.
Something like this is expected in case of successfull delivery:
Sends -> Deliveries -> Success
I know that there are other "success" events like Opens, Clicks, Subscriptions, but they require additional action from the end-user.
Implementation details
I use Verified identity as an email sender.
A configuration set is used to redirect status events to SNS.
Finally, SQS is subscribed to this SNS to have all events in one place.
I tried several ways to send an email:
Java code using AWS SES SDK
Sending simulator with predefined and custom recipient's
The result is the same (as described above)
I think it is impossible to have a Success status because AWS cannot guarantee when the recipient mail server will reply with a Hard Bounce. You yourself have to define how long to you want to wait until you consider a delivery as successful. For example, if no hard bounce after 5 minutes, then it is a success.
If your use case is for analytics, I will simply capture more event types (for example log both Deliveries and Hard Bounces), and then count my success as Count of Deliveries - Count of Hard Bounces.
If your use case is for event-driven workloads, we need to define first what is considered a Success. For example, if we define Success as no Hard Bounce after 5 minutes, we can configure a Lambda function to trigger 5 minutes after a Delivery event. In the function, check if a subsequent Bounce event occurred. If not, the delivery is considered successful and then you can proceed to do what you want to do.
This is what I got from aws support about delivery status of an email.
Amazon SES will continue making several delivery attempts until
receiving a successful response from the recipient mail server, or
until 840 minutes elapse. If Amazon SES is still unable to deliver
the email/message during this period, it stops sending the email and
will then return a bounce message/notification.
According to this you can't be sure about the bounce or any other status within 5 minutes.
AWS does not have visibility to confirm if the Recipient Mail Server was able to deliver the message to the recipient email address when you get a 250 OK(it's confirmation that aws has delivered the message to recipient's mail server).
So there is no way you can be sure.
I've created an AWS SQS, and I'm just testing through the console by sending some messages. I was expecting to see the messages that I've sent listed under the "Received messages" title. But, to my surprise, approximately only one of every ten messages that I send seems to be received.
I test this, as shown in the screenshot, by clicking on "Poll for Messages" and then on "Send a message".
I'm bewildered by the fact that sometimes a message is actually received and displayed.
Wouldn't the expected behavior be to receive every single message I send?
Any idea on what's going on, please?
Have you checked message deduplication is active? There might be some deduplication by message data itself.
Or another possible reason might be some other consumer gets the message before your poll.
I will try to express my question, I'm sorry if is not the correct way to do it.
I have an AWS SES configured to receive emails from my customers, sometimes the client get in a list and try to send an email too large (above 10MB), and my costumer start to receive bounced emails from all recipients in that list.
The bounce happens when my client tries to send an email for another people but the email of my company appears on CC field.
E.g:
the client sent an email:
TO: wherever#google.com
CC: mycompany#mycompany.com (this one will be sent for my SES); [a lot of other emails.........list]
This mail will be more large than 10MB (my SES must have to treat it).
This chain wil generate an bounced mail for my costumer, once that my email appears on CC list.
It's a little bit complex to express, but basicaly is it.
I'd like to know if is possible to track this attempts when the costumer receive the first bounce email from AWS. and to trigger a alert for me that the costumer is getting in a bounced list.
You can absolutely do this, SES supports notifications per type to SNS. The types are Delivery, Bounce, Complaint.
Each type can be registered to an SNS topic which you can subscribe a Lambda function to.
This Lambda function can then perform any logical decisions that you would like for your workflow.
In addition you can subscribe any email addresses you want to receive the raw notification that it was undelivered, although you will need to confirm there subscriptions before they can receive notifications. This would be ideal for a support inbox for example.
The AWS documentation contains more information about notifications
my tried wayI am trying to know when i am sending push notification to users they will open the notification or not. i am able to get the number of sent notification or number of successful and failed notification but i am unable to get the user response record.I am using aws sns push notification with fcm
it's easy!
Just put a little code in notification code, when user clicked the notification it gets the value from the database which is 0 when you start sending the notification, and add +1 in it and again store that value in the database.
This is the simple way you can check how many people open your notification.

We're doing everything we can think of to limit the number of complaints we receive and will immediately remove anyone who marks us as junk that does not need to receive our emails. However, the last handful of complaints we've received have come from transactional emails of people who are receiving our company's services and NEED to receive everything we send transactionally as a critical part of our service. (e.g. We are booking their travel on their behalf and we need to send them verification emails to confirm their booking details.)
We're assuming that most of these complaints are somehow either false positives or are being done on accident. One customer confirmed that they did not click the junk mail button but it ended up in their junk folder and they moved it to their inbox. Some questions:
Can a TiS complaint be triggered by any means other than the user manually marking an email as junk in their email client? (Can automatic spam filters trigger this complaint? AWS documentation specifies only clicking the junk button.)
Besides contacting each individual personally, what would you suggest we do? Our complaint rate is continuing to rise even though we are taking action on every one.
