How do I validate my SPF setup in Marketo?

Validating your SPF setup in Marketo involves a multi-faceted approach, combining technical verification with practical testing. Experts and documentation consistently emphasize the importance of ensuring your SPF record includes Marketo's sending IPs, which can be obtained from Marketo support, and that the SPF setup aligns with the From header. Online tools like MXToolbox, DMARC Analyzer, and SPF record lookup tools, as well as command-line tools like `dig`, are recommended for checking the syntax, content, and validity of the SPF record. Common errors to avoid include exceeding the 10 DNS lookup limit, having multiple SPF records, and incorrect syntax. The SPF record should start with `v=spf1`, end with a qualifier (e.g., `-all`, `~all`), and be published as a TXT record in your DNS settings. After publishing, allow up to 48 hours for DNS changes to propagate, and send test emails to various email providers to examine headers for SPF pass/fail status. Properly validating ensures email deliverability and prevents spoofing, requiring regular checks, especially after infrastructure changes, and careful attention to authorized sending sources and correct syntax.

Validating your SPF setup in Marketo involves several important steps and considerations. First, use online SPF record checker tools like MXToolbox or DMARC Analyzer or the `dig` command to verify the SPF record's syntax and content, ensuring it includes all necessary IPs for your email sending domains. Common errors to check for include exceeding the 10 DNS lookup limit and having multiple SPF records. Publishing your SPF record as a TXT record in your domain's DNS settings is crucial. It's also advised to send test emails to various email providers and examine the email headers to check if SPF passed. Allow up to 48 hours for DNS changes to propagate before testing, and regularly check the setup, particularly after changes to your sending infrastructure. Properly validating the SPF setup is crucial for email deliverability and preventing spoofing.

Validating your SPF setup in Marketo involves confirming that the SPF record is valid and aligned with the From header, particularly focusing on the return path (envelope.eversource.com). Experts emphasize checking the SPF record to ensure it includes all legitimate sending sources and doesn't exceed the DNS lookup limit. They also highlight that the SPF record should start with `v=spf1` and end with a qualifier like `-all`, `~all`, or `?all`, and that the mechanisms within the record define authorized sending servers. Tools like DNS record viewers can be used to verify the content and validity of the SPF record.

Validating your SPF setup in Marketo involves several key steps, including ensuring your SPF record includes Marketo's sending IPs (obtainable from Marketo support) and using DNS lookup tools to confirm the record is published correctly. Online tools such as MXToolbox or SPF Record Check can verify if your SPF record is valid and properly configured. Testing is crucial after setup, with tools like SPF record lookup tools checking for syntax errors, multiple SPF records (which are invalid), and inclusion of all sending sources. Validation also includes verifying syntax, ensuring the DNS lookup limit is not exceeded (maximum 10 lookups), and confirming authorized sending sources. SPF records must start with `v=spf1` and include mechanisms like `include`, `a`, `mx`, `ip4`, and `ip6` to specify authorized sources, ending with a qualifier like `-all`, `~all`, or `+all`.
