SNS topic email subscription - did not receive Subscription Confirmation

Question

I created an SNS topic and subscribed to it through email protocol. I have 3 subscriptions - one for individual email address and two for group email addresses. The individual email one is confirmed, I received Subscription Confirmation right away. However, I did not receive any confirmation emails for my group email. One of the group emails are a google accounts that I have admin access to, so I could check the settings.

Steps I've already taken:
- Checked Email Configuration -  there are no filters or rules in your group email that might be blocking or redirecting emails from AWS (especially from no-reply@sns.amazonaws.com)
- checked spam folder
- Resend the Confirmation (actualy, there is no option to resend confirmation. I just clicked "request confirmation" button
- Test with an Alternative Email - as I said at the beginning, I used an individual account to check and it worked

Accepted Answer

In google works space its usually because allow incoming email from outside the org isn't enabled

If external users can’t email your group, check to make sure your settings allow for external emails.
If you’re an administrator, you can set the option to allow external emails for all of your organization’s groups in the Admin console.

Sign in to your Google Admin console.
1. Sign in using an administrator account, not your current account userabcd@gmail.com
2. In the Admin console, go to Menu and then Apps > Google Workspace > Groups for Business.
3. Click Sharing settings.
4. Check the Group owners can allow incoming email from outside the organization box.
5. Click Save.
6.

If you’re a group owner or manager, you can allow external emails to the group in Google Groups. If you’re signed into a work or school account, the options you see depend on the settings set by your administrator for all groups.

1. Sign in to Google Groups.
2. Click the name of a group.
3. On the left, click Group settings > General.
4. Under Who can post, make sure Anyone on the web is selected.
5. Click Save changes.
