Tag: spf record

An SPF record is a DNS entry that lists which mail servers may send e-mail on behalf of a domain. Receiving servers check it to decide whether a message claiming to come from your company is genuine. A missing or incorrect SPF record makes legitimate newsletters and invoices more likely to land in spam, and makes it easier for others to spoof your address. SPF works best together with DKIM and DMARC, which add signatures and a policy for failed checks. Internet Solutions hosts business e-mail for more than a thousand companies on our own servers, and correct DNS records are part of setting up mail on a domain. We also run e-mail marketing to opt-in lists, where authentication has a direct effect on how many messages reach the inbox. Checking SPF is one of the first steps when deliverability drops.
