Authenticate your domain with SpinOffice CRM by modifying your domain's SFP records. These changes allow your outgoing emails to appear to come from your domain, instead of from our server. Your domain provider knows exactly how and where to adjust it; SPF records are set in the DNS zone of the domain name.
SPF: Create a TXT record for your domain with:
v=spf1 include:spf.spinoffice-crm.com ~all
After you've made the required SPF changes, please wait 24-48 hours for the changes to propagate.
