Steps to reproduce

Here's a sample service class that sends an email using a template

<?php
/*

namespace Ioweb\Base\Service;

use Exception;
use Magento\Framework\App\Area;
use Magento\Framework\Escaper;
use Magento\Framework\Mail\MailMessageInterfaceFactory;
use Magento\Framework\Mail\MessageInterfaceFactory;
use Magento\Framework\Mail\Template\TransportBuilder;
use Magento\Framework\Mail\TransportInterfaceFactory;
use Magento\Framework\Translate\Inline\StateInterface;
use Magento\Store\Model\StoreManagerInterface;

class MailWithTemplate
{
    protected $escaper;
    protected $inlineTranslation;
    protected $mailTransportFactory;
    protected $messageInterfaceFactory;
    protected $storeManager;
    protected $transportBuilder;

    public function __construct(
        StateInterface            $inlineTranslation,
        Escaper                   $escaper,
        TransportBuilder          $transportBuilder,
        MessageInterfaceFactory   $messageInterfaceFactory,
        TransportInterfaceFactory $mailTransportFactory,
        StoreManagerInterface     $storeManager
    )
    {
        $this->inlineTranslation = $inlineTranslation;
        $this->escaper = $escaper;
        $this->transportBuilder = $transportBuilder;
        $this->messageInterfaceFactory = $messageInterfaceFactory;
        $this->mailTransportFactory = $mailTransportFactory;
        $this->storeManager = $storeManager;
    }

    /**
     * @param array $from [name, email]
     * @param $to
     * @param $templateIdentifier
     * @param $vars
     * @return void
     */
    public function execute($from, $to, $templateIdentifier, $vars, $storeId = null, $area = Area::AREA_FRONTEND)
    {
        try {
            $this->inlineTranslation->suspend();
            $this->transportBuilder->setTemplateIdentifier($templateIdentifier);
            $this->transportBuilder->setTemplateOptions(
                [
                    'area' => !empty($area) ? $area : Area::AREA_FRONTEND,
                    'store' => !empty($storeId) ? $storeId : $this->storeManager->getStore()->getId(),
                ]
            );
            $this->transportBuilder->setTemplateVars($vars);
            $this->transportBuilder
                ->setFromByScope($from)
                ->addTo($to, $to);

            $transport = $this->transportBuilder->getTransport();
            $transport->sendMessage();
            $this->inlineTranslation->resume();
        } catch (Exception $e) {
            return;
        }
    }
}

I'm now trying in a CLI command to send an email template using this service class for storeId 5 which is using Greek locale.

I've added the proper translation files but the message keeps sending in english.

Header / Footer are loaded from english store

Here's my email template

<!-- Email subject -->
<!--@subject {{trans "Enjoy Your Exclusive Black Friday Discount!"}}  @-->

{{template config_path="design/email/header_template"}}

<!-- Header -->
<h1 style="text-align: center">{{trans 'Black Friday Special!'}}</h1>

<!-- Main Content -->
<div>
    <div class="content io-content">
        <p>{{trans 'We are thrilled to offer you an exclusive Black Friday discount for your recent order %increment_id! Use the coupon code below to enjoy special savings on your next purchase.' increment_id=$increment_id}}</p>

        <!-- Coupon Code -->
        <p><strong>{{trans 'Coupon Code:'}}</strong> {{var coupon_code}}</p>

        <!-- Expiration Date -->
        <p><strong>{{trans 'Expires On:'}}</strong> {{var expiration_date|raw}}</p>
    </div>
</div>

<!-- Footer -->
{{template config_path="design/email/footer_template"}}

Expected result

Message is sent translated

Actual result

Message is using default English locale

It seems in order to make them translate I had to follow the solution from this commit for a similar issue

1455889

                $areaModel = $this->areaList->getArea($this->appState->getAreaCode());
                $areaModel->load(Area::PART_DESIGN);
                $areaModel->load(Area::PART_TRANSLATE);

I think this is missing from the template rendering where it's processing the design parameters added by

$this->transportBuilder->setTemplateOptions([])

Hello @ioweb-gr,

Thank you for the report and collaboration!

We were able to reproduce this issue on 2.4-develop.
We created a custom module with German language pack installed.
Please take a look at the screenshot below:

Here we are sending the email through CLI for store id 2(which is German store), and we were not able to get the translated message.
Hence confirming the issue.

Please find the attached custom module used to reproduce this issue.

Thank you.
