Your reply is a godsend. Thanks!
A quick follow-up question. Do we need to add more DMARC for each email address we use to send customer email from Shopify?
In your example, you had [email removed] for this entry
Value of TXT record = v=DMARC1; p=none; [email removed]
If you have another email 'order* @StephensWorld .ca",*do you need to add another DMARC? Really appreciate it!
