Email deliverability seems to be an increasing problem these days. One issue that can be flagged by mail-tester.com if you use the email address it gives to send an email from the oeredsr tab in Sellerdeck is that your message does not contain a List-Unsubscribe header.
This is easily remedied in Selerdeck. First you need an unsubscribe email address on your domain. It needs checking regularly so maybe make it a forwarder to your main email address.
The you need a URL where the customer can be directed to im order to unsubscribe, either a custom page or maybe the contact us page.
The header will then look something like this
List-Unsubscribe: <mailto: email@example.com?subject=unsubscribe>, <http://www.graphicz.co.uk/https://www.graphicz.co.uk/contact.php>
If you open the file ‘SmtpLibrary.pm’ and search for: –
You will see all of the email headers there, so I think you should be able to add it just above: –
my $mail_headers = "From: $mail_from\n". "To: $mail_to\n". "Reply-to: $mail_replyTo\n". "Subject: ".encode('MIME-Header', $mail_subject)."\n". "Date: $sNow\n"; "List-Unsubscribe: <mailto: firstname.lastname@example.org?subject=unsubscribe>, <https://www.graphicz.co.uk/contact.php>"; "MIME-Version: 1.0\n";
Then upload and test. Provided without warranty express or implied. Thanks to Gary Green at Sellerdeck Support
It is also worth adding a DMARC record to your domain name’s Zome editor:
_dmarc.graphicz.co.uk v=DMARC1; p=none
And in the Sellerdeck Page type ‘HTML Email Cart’ remove the cmpany logo leaving the company name in plain text and replace
<actinic:variable name="CatalogHomeURL" /> <actinic:variable name="CatalogURL" />info.html
with the hard coded domain name and info page link as the variables do not always work in the recipient email
