DMARC, SPF, and DKIM Settings
phpList.com servers have the correct DMARC, SPF, and DKIM settings configured automatically for each account. DMARC is currently available for hosted-VPS accounts upon request. DMARC for other types of accounts is coming soon.
If you have access to the DNS settings relating to the domain of the ‘From’ address used by your campaigns, then it is possible to potentially improve campaign deliverability further by adding an SPF record to the server which hosts that domain.
To do so, add “include phplist.com” to your records. The following record may be used as a template and adapted to your requirements:
v=spf1 include:spf.phplist.com ~all
