Get info from pop-up form into email template

Question

I want to get values from this form fields and put into email template. What I was suppose to do? For every field I need to create custom variable, and bind it on field? Documentation is not too informative, as I think.

You can create a <form> and assign input field name as follows:

<form action="<?= $block->escapeUrl($block->getSaveFormAction()) ?>"
        id="newsletter-form"
        class="newsletter-form"
        method="post"
        data-hasrequired="<?php /* @escapeNotVerified */ echo __('* Required Fields') ?>"
        data-mage-init='{"validation":{}}'>
    ...
    <input type="text" name="newsletter[firstname]" placeholder="First Name" />
    <input type="text" name="newsletter[lastname]" placeholder="Last Name" />
    <input type="text" name="newsletter[email]" placeholder="Email Address" />
    ...
</form>

So you can get form values in your controller as follows:

Namespace/Module/Controller/Index/Save.php

public function execute() {
    $post = (array) $this->getRequest()->getPost();
    // Get newsletter data
    $newsletterData = $post['newsletter'];
    $transport = $this->transportBuilder
            ->setTemplateIdentifier('newsletter_email_email_template')
            ->setTemplateOptions([
                    'area' => \Magento\Framework\App\Area::AREA_FRONTEND,
                    'store' => $storeId()
                ])
            ->setTemplateVars($newsletterData) // set newsletter data in email template
            ->setFrom(['email' => $fromEmail, 'name' => $fromName])
            ->addTo($data['email'])
            ->setReplyTo($fromEmail, $fromName)
            ->getTransport();
        $transport->sendMessage();
}

You will get newsletter data in form of following variables:

Namespace/Module/view/frontend/email/newsletter.html

First Name: {{var firstname}}
Last Name: {{var lastname}}
Email Address: {{var email}}

I hope this may helpful to you!!
