By default we send email surveys using SendGrid headers. If you'd like to further increase trust and delivery rate of your email surveys we can set up email white-label for your domain.
Domain whitelabeling adds an SPF (Sender Policy Framework) record to your domain and DKIM (DomainKeys Identified Mail) entries, which effectively authorizes and authenticates SatisMeter sending on behalf of your domain.
This requires you to add few record to your DNS configuration. Please get in touch via our live chat and we'll help you setting this up.
