Deliverability test (SPF)

Brief description

This test checks the probability that the mailing will be delivered. Technically, the test checks whether an SPF record for the mail server is available in the DNS server of a specific domain. In the case of a suspected bogus sender email address, the mailing may not be delivered.

Details

SPF stands for Sender Policy Framework and is a technology designed to make falsifying sender addresses of an email more difficult. The server receiving the mailing checks whether an SPF record for the mail server is available in the DNS server for a specific domain.

Possible test results

• green = There is a positive SPF record for the mail server, which means that the mail server is authorised to send mailings from this domain. The mailing is sent.
• orange = There is no SPF record or it cannot be determined. If the mail server is not listed in the SPF record at all, sending of the mailing is not prevented. However, some providers issue a negative spam rating or reject the mailing. Or: if there is no SPF record for the domain, the sender must be accepted. The mailing is sent. Some providers give bonus points for a correct and existing SPF record.
• red = There is a negative SPF record for the mail server. It prohibits the sending of the mailing via this mail server.

Ask your Inxmail Professional administrator if you do not have an SPF record for your domain. This record increases the deliverability of your mailings.
