Email Authentication (SPF, DKIM , DMARC)
Configuring email authentication is a best practice and helps getting the best results from your email campaigns. It tells Internet Service Providers that our mailservers are authorized to send mails on your behalf and that the mails are legitimate.
For large email senders who send more than 5,000 emails per day to Gmail or Yahoo addresses, email authentication is required, as Gmail and Yahoo require emails in such volumes to be authenticated.
Choose "Sending Newsletters" under the "Configuration" tab to receive instructions for the DNS records to create and/or to check that the requested records have been created correctly.
