Common SPF FAQs

What is an SPF Record?

An SPF (Sender Policy Framework) record is a type of DNS record that identifies which mail servers are permitted to send email on behalf of your domain.

What information is found in an SPF Record?

A new SPF record will typically include:

Mail Server IPs: An SPF Record lists the IP addresses of the mail servers that are authorized to send emails on behalf of the domain. This can include both IPv4 and IPv6 addresses.
Subdomains: SPF records can define whether subdomains are permitted to send emails for the main domain.
Include Statement: It may contain an "include" statement to authorize emails sent from servers of third-party services, like email marketing platforms.
All Mechanism: The record ends with an 'all' mechanism (like -all or ~all), defining how servers not listed in the SPF record should be treated (e.g., as unauthorized senders). Essentially, an SPF record lists the authorized sending sources for a domain's emails, playing an important role in preventing email spoofing and ensuring email security.

How does the SPF Record Generator work?

MailWizz's SPF Record Generator creates a valid SPF record by asking for your domain's mail-sending hosts and IP addresses, then generates a TXT record that you can add to your DNS through your DNS provider.

Why do I need an SPF record for my domain?

An SPF record helps prevent spammers from sending messages with forged From addresses at your domain, enhancing your email security and deliverability. An SPF record is a crucial component of domain-based message authentication.

What should I do after generating an SPF record?

After generating an SPF record, you should add it to your DNS configuration as a TXT record. This ensures that email receivers can verify that messages appearing to come from your domain are authentic.

Can I have multiple SPF records for my domain?

No, you should only have one SPF record for your domain. Having multiple SPF records can lead to validation issues and potentially cause legitimate emails to be marked as spam.

How does an SPF record differ from a MX record?

While both SPF and MX records are essential for email functionality, they serve different purposes. An SPF record specifies which mail servers are authorized to send emails on behalf of your domain, helping to prevent email spoofing. On the other hand, a MX record determines which server receives emails sent to your domain. Together, they ensure both outgoing and incoming emails are securely managed.
