SPF records allow our servers to send mail on behalf of your domain and email address. Without a valid SPF record setup within your domain's DNS zone file, the mail that would originate from our servers (such as forms, store notifications / receipts, and Mass Mails) could appear as SPAM to many email providers and Internet Service Providers. Some recipients may receive the mail, yet others may see it in their SPAM folders, while others may never recieve it at all as their mail provider may block the mail entirely.

To alleviate this, you'll want to add a TXT record within your domain's DNS that allows our mail sending IP's to send mail on behalf of your domain by adding the following:
ip4:184.108.40.206 ip4:220.127.116.11 ip4:18.104.22.168 ip4:22.214.171.124 ip4:126.96.36.199 ip4:188.8.131.52
Therefore a valid SPF record would appear as:
v=spf1 a mx ptr ip4:184.108.40.206 ip4:220.127.116.11 ip4:18.104.22.168 ip4:22.214.171.124 ip4:126.96.36.199 ip4:188.8.131.52 ~all
While the above is just an example and what we use for most clients, it would allow our system to send mail on your behalf. Please note that this could limit other mail functionality you may have in place. Be sure you check with your IT / DNS provider or our support team if you have any questions. If you are unsure if this record exists, or how to create it, please submit a support ticket within your admin area and we’ll be glad to check and provide guidance on creating the SPF record.
