When you send emails through Ontraport to Gmail and Outlook addresses, the emails will automatically include the message “Sent by yoursite.com via ontramail.com” after your email “from” address. This is required to meet authentication standards and ensure your emails get delivered.
However, you can remove this message by modifying your DNS settings. If you are not familiar with how to do this we strongly recommend hiring a qualified web developer to complete this process. We encourage this because you can permanently lose all content, email service, etc. on that domain if other settings are inadvertently changed. The change will be final once you have hosted the necessary DNS records and our postmasters have confirmed everything.


The steps outlined below are intended to be used only by qualified web developers or those who feel confident in their understanding of this process.

  • To get started make sure you have:
    1. A privately hosted email “from” address. It cannot be a free email address such as @gmail.com, @yahoo.com, @hotmail, etc.
    2. Access to your domain’s DNS records.
  • Log into the DNS manager of your domain registrar and add the following records:
    1. Record 1: DKIM
      • Type: TXT
      • Name: ontramail._domainkey
      • Value: “v=DKIM1;k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDiHV+GFJUPAtmIh26KHbn5PZXEFm3XK2XjEs4HFOSDZthULWyGvI5CqfYmNm7LFTWC3v5m6CtbLeNgDu0RwTw+94TSryL4ZYC6PESaJCHurmpREZTh+UFlLliRip3reqrNfoYpkiWa6fgu9vbyZob+W3d+leBP/p0mmOXeJiOjKwIDAQAB;”
    2. Record 2: SPF
      • Type: TXT
      • Name: Blank or @ (the root domain)
      • Value: “v=spf1 include:_spf-moon-ray.ontramail.com include:_spf-ontramail.ontramail.com ~all”
      • If you are sending email from other services using this domain, you will need to add the mailing IPs of those other services in your SPF record as well. These can be added as new “ip4:” items in the value. In addition, add any other mailing domains that your mail might come from in an “include:example.com” item.
