It's best practice to create an SPF entry for Mail Transfer Agents (MTAs) to validate incoming mail is from an authorized domain. This anti-spam technique must be published in the DNS by the domain's administrators.
While the entry is not mandatory, we do recommend creating it. SPF entries improve your organization’s email deliverability when sent out of ROI. The entry allows your organization's domain to validate your ROI tactic sends and avoid being labeled as spam or a phising technique by the MTAs.
Many organizations already have at least one SPF entry because their email server is outsourced.
If you already have a SPF entry, ask your DNS admin to add the following: "include:_spf.messagegears.net".
If you do not have a SPF entry, ask your DNS admin to add the following: "v=spf1 include:_spf.messagegears.net ~all".

A word of caution -- if not implemented correctly by your DNS admin, there could be negative effects on other mailings such as emails sent from Outlook, Apple Mail or other email clients used to send email. It is extremely important your DNS admin determines how this entry may impact deliverability of personal emails. Additional entries may need to be made to ensure the emails sent personally are not negatively impacted.
Below is a process diagram of the process. For example, if AJ&MF CO. uses marketing@AJMF.com as their From Name when sending out ROI tactics, an SPF entry should be made by the AJ&MF DNS admin for the AJMF.com domain prior to using marketing@AJMF.com.
