Once you have all the servers which may be used to send email for your domain indicated by one of the SPF mechanisms, and have included any relevant service providers by domain name, the only thing left to do is finish adding the record to the system. If you are unsure what mailservers will be sending email for your domain you should contact your ISP or email provider to make sure your information is correct. It is also a good idea to contact any provider you think you should add to SPF through the include: mechanism to make sure you have the correct domain names for your purposes.

You will need to enter your domain name, or the host of that domain which you are adding the SPF data for, on the "host" field on the left of the page, and the SPF data you have decided on in the right hand "text record" field. You then click "next" to confirm the changes.

When you confirm the change you will receive a message letting you know how soon the changes will be loaded onto the nameservers and how long the change will take to propagate world-wide. Click "done" on that page and you will return to the main member page and you are done adding SPF data to your domain.
