Authentication of domains will improve your email deliverability and stop your e-mails from going into the SPAM folder. This will also remove "via picpicsocial.com" from the e-mails you send. You need to be on the AGENCY plan or higher for this feature.

Edit the DNS settings for your domain. Replace yourdomain.com with the domain you want to authenticate. Once you have done this, contact us and we will do the rest.
