Ensure that Messages are Delivered to Email

To help ensure that email messages (like invoices and service notices) reach your recipients inbox, we recommend adding RingLogix to your SPF DNS record.

SPF (Sender Policy Framework) DNS records are used by many email providers to identify which mail servers are authorized to send email messages on behalf of your domain.

Any emails sent from a server that is not authorized via an SPF record is likely to be marked as spam and not reach the recipients inbox.



Managing DNS records is an ADVANCED network function. Only administrators with knowledge on how DNS works should attempt to make these changes. RingLogix does not offer DNS management services.

Limitation Details: As outlined in Section 10.1 of the SPF RFC, SPF implementations must adhere to a strict cap on the number of DNS lookups during an SPF check. Specifically, this limit is set at a maximum of 10 lookups. These lookups encompass any queries triggered by the “include” mechanism or the “redirect” modifier.

The Basics.

Depending on your provider, you may need to add quotation marks around your entire SPF record.

Testing your SPF record.

DNS updates can take anywhere from a few minutes to a couple days to apply.

You should test your entries after about 1 hour.

If your first test fails, don’t’ be concerned and just wait a bit longer (up to 48 hours).

We recommend using the SPF Lookup tool from MXToolBox:

If your SPF lookup is failing after 48 hours you will need to contact your DNS admin or provider for assistance.
