After migration from Mautic 4.1.11 to 5.1 our AWS SES email configuration was not working anymore. As a result campaigns got paused and all test mails resulted in errors.
After some investigation we found out that the DSN field in the email settings contained ‘mautic.transport.amazon’. After only changing this field to ‘smtp’ the email configuration started to work again. Only had to start the paused campaigns again.
Hope this helps.

If you want to use SES API, then set **Host** to “default” and add option for region like below image.
Make sure you have installed mailer that supports SES API like `symfony/amazon-mailer`.
It can be installed with `composer require symfony/amazon-mailer` and then clear cache with `php bin/console cache:clear`.

I’m trying to run the command composer require symfony where my project is, which is on a shared server."
Problem 1
- symfony/redis-messenger v6.0.19 requires ext-redis \* → it is missing from your system. Install or enable PHP’s re dis extension.
- mautic/core-lib 5.0.0-dev requires symfony/messenger ~5.4 → satisfiable by symfony/messenger[v5.4.35].
- symfony/messenger v5.4.35 requires symfony/redis-messenger ^5.1|^6.0 → satisfiable by symfony/redis-messenger[v6. 0.19].
- Root composer.json requires mautic/core-lib ^5.0 → satisfiable by mautic/core-lib[5.0.0-dev].
To enable extensions, verify that they are enabled in your .ini files:
- /opt/cpanel/ea-php82/root/etc/php.ini
- /opt/cpanel/ea-php82/root/etc/php.d/10-opcache.ini

You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-redis` to temporarily ignore these required extensio ns.
You can also try re-running composer require with an explicit version constraint, e.g. “composer require symfony/amazon- mailer:\*” to figure out if any version is installable, or “composer require symfony/amazon-mailer:^2.1” if you know whic h you need.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Can you try with `--ignore-platform-reqs`?
eg `composer require symfony/amazon-mailer --ignore-platform-reqs`

At this point just use `pm-pmaas/etailors_amazon_ses` which can be installed without composer.
Steps:
1. Go to `plugins` folder with `cd plugins`
2. Clone `pm-pmaas/etailors_amazon_ses` repository into plugins folder with `git clone https://github.com/pm-pmaas/etailors_amazon_ses.git AmazonSesBundle`
There should be now new folder named `AmazonSesBundle` in `plugins` folder.
3. Go back to Mautic root folder with `cd ..`
4. Clear Mautic cache with `php bin/console cache:clear`
5. Set scheme to `mautic+ses+api` instead of `ses+api`

After clearing Mautic cache, go **Settings** → **Integrations** → **Plugins** → Click on **Install/Upgrade Plugins** button, it should list **Amazon SES** after that

Now, when I set it to mautic+ses+api an error occurs, and when I set it to ses+api the page breaks.

Looks like you already have different mailer installed.
Please delete `AmazonSESBundle`/`AmazonSesBundle` from `plugins` folder and try again these steps I provided earlier.
Make sure there is only `AmazonSesBundle` (not `AmazonSESBundle` or anything else).

This is what `pm-pmaas/etailors_amazon_ses` looks like

The plugin doesn’t appear, but it seems to be active because the error now was different.

Set **Host** to “default”
Set **Port** to empty
DSN should look like `mautic+ses+api://:@default?region=`

You can check logs under `/var/logs`
Do you have production access enabled in Amazon SES? Not in sandbox.
If credentials are for SMTP, then you need create IAM user and attach SES policy to this user, then create API credentials for this IAM user.
