If you're receiving complaints from customers that they are not receiving their order confirmation emails, this post will point out ways you can set up your email strategy to prevent order confirmation emails from going to spam as well as a few things your organization could consider doing as well.
What Brandibble does
Brandibble uses Amazon's SES outbound email service to send order confirmation emails. Amazon SES assists us in authenticating all emails sent through the system using SPF checks, DKIM checks and reverse DNS paths. These 3 checks help spam filters know the emails we send are coming from where we say they are coming from.
We make it easy for servers to recognize the order confirmation emails by using a consistent IP address to send emails, we only send emails to one specific person, and we always use the same "From" address.
We only send order confirmation emails to those who order online, and therefore have "opted in" to receive the confirmation email.
We keep the image to text ratio low in our confirmation emails (a high ratio makes spam filters suspicious), and we follow HTML standards for the email, and the content of the email is consistent with the subject.
What You Can Do
Make sure your organization is not sending any bulk or promotional emails from the same email in which you send order confirmation emails created by the Brandibble system. For example, if you are currently using "orders@coffeeshop.com" to send order confirmation emails, consider creating a separate email for promotional emails.
Consider asking customers to add "orders@coffeeshop.com" to their contact list. You could add this wording to the checkout page.
Consider asking customers whose confirmation emails are sent to spam to click the "Not Spam" button in their email to help them receive order confirmation emails in the future.
Consider setting the subject of your order confirmation email to include your name. For example, "Your Coffee Shop Order is Confirmed". A common spam preventing recommendation is to make sure your “From” field and subject line are branded for better recognition. You can easily make this change in the admin tool at Settings >> Email Confirmations >> Email Subject.
Consider monitoring bounce/complaint/successful delivery statistics for all of your email addresses. You should automatically unsubscribe users whose addresses bounce multiple pieces of mail, as they would affect your statistics, and contribute to your mail being sent to spam.
