I'm trying to insert custom variable(company, Phone Number) into my customer email template. But it's not working for me.

 template config_path="design/email/header_template"

 <p class="greeting">trans "%name," name=$customer.name</p>
 <p>trans "Welcome to %store_name." store_name=$store.getFrontendName()</p>
 <p>
 raw
 </p>
 <table class="email-credentials">
 <tr>
 <th>trans "Email:"</th>
 <td>var customer.email</td>
 </tr>
 <tr>
 <th>trans "Password:"</th>
 <td><em>trans "Password you set when creating account"</em></td>
 </tr>
 </table>
 <p>
 trans
 'Forgot your account password? Click <a href="%reset_url">here</a> to reset it.'

 reset_url="$this.getUrl($store,'customer/account/createPassword/',[_query:[id:$customer.id,token:$customer.rp_token],_nosid:1])"
 
 </p>
 <br />
 <p>
 var company
 </p>
 <br/>
 <p>trans "When you sign in to your account, you will be able to:"</p>
 <table class="email-features">
 <tr>
 <td>
 <table>
 <tr>
 <td>
 <img src="view url='Magento_Customer/images/icn_checkout.png'" height="30" width="30" alt="trans 'Quick Checkout'" />
 </td>
 <td>
 <h3>trans "Proceed through checkout faster"</h3>
 </td>
 </tr>
 </table>

Any help on this?

Try with:

var customer.company and var customer.phone_number

If it's not working, then the customer object for email templates doesn't contain the newly added customer data (company and phone number).

You can check the function newAccount() in vendormagentomodule-customerModelEmailNotification.php which contains $customerEmailData that holds all customer related data for the email template.

You could create a plugin or override to add your custom data to it.
