To increase the deliverability rate of your Remarkety emails (ie - decrease the chance that they will be automatically be marked as spam), it's a good practice to have an SPF record in place.
An SPF record is a simple DNS record which tells other email providers (such as gmail, Hotmail, Yahoo, etc) that Remarkety is authorized to send email on your behalf. You need to be somewhat technical and understand how to manage the DNS records for your domain.
TXT entry needs to be added to your root domain:
v=spf1 a mx include:spf.remarkety.com ~all
If you already have an SPF record set up, for example for Google Apps, you will need to modify it so that it includes spf.remarkety.com as well. For example, if your record looks like this:
v=spf1 a include:_spf.google.com ~all
You need to modify it to look like this:
v=spf1 a include:_spf.google.com include:spf.remarkety.com ~all
