hi, I apologize but I can not figure out how and where to place my custome them for the confirmation email and welcome.
I modified the code I found in “collection Registration” -> Message Template
the code is written by me this:
<!DOCTYPE html>
<html>
    <head>
        <!-- General styles, not used by all email clients -->
        <style type="text/css" media="all">
            a {
                text-decoration: none;
                color: #f1c8b2;
            }
        </style>
    </head>
    
    <!-- KEEP THE TAMPLE SIMPLE: THOSE ARE SERVICE MESSAGES. -->
    <body style="margin: 0;">
        <!-- Top title with dark background #333, font color #fff, font size 32px -->
        <table style="background-color: #fff; width: 100%; color: #fff; font-size: 32px">
            <tr>
                <td height="150" style=" text-align: center">
                    <img src="http://mydominio.com/wp-content/uploads/2017/02/logo150.png">
                </td>
            </tr>
        </table>
        <!-- Main table 100% wide with background color #eee -->    
        <table style="background-color: #fff; width: 100%;">
            <tr>
                <td align="center"  style="padding: 25px;">
                    <!-- Content table with backgdound color #fff, width 500px -->
                    <table style="background-color: #fff; width: 500px; border: 1px solid #f1c8b2;">
                        <tr>
                            <td style="padding: 25px; font-size: 16px;">
                                <!-- The {message} tag is replaced with one of confirmation, welcome or goodbye messages -->
                                <!-- Messages content can be configured on Newsletter List Building panels --> 
                                {message}
                                
                                <!-- Signature if not already added to single messages (surround with <p>) -->
                            </td>
                        </tr>
                    </table>
                </td>
            </tr>
        </table>
    </body>
</html>
But I do not receive any email, what I can do? Please can you help me?
thank you!
