Emailing Promotion Codes
Once you have a Promo Code created, you will want to let your customers know about it. One of the best ways to let them know is by email.
Third-Party Email Marketing
If you are managing an email list outside of Diner Websites, just paste the promo code you created into the email marketing software and sent it to your customers. Don't forget to add a link to the online ordering.
Diner Website Email Marketing
If you're using Diner Websites Email Marketing, all your customer that have previously placed orders on your store will be automatically imported into the Diner Website Dashboard Email Marketing Module.
You can email them directly from the dashboard by just adding the email content, paste the promo code, and either scheduling or sending the email.
