How to fix missing spf on Webflow

Steps for Webflow

1. If your domain is registered with Webflow: Webflow Dashboard → Webflow Workspace → Domains → click your domain → DNS Settings.
2. Add a new TXT record: Name = '@', Value = your SPF string. Save.
3. If the domain is registered elsewhere (GoDaddy, Namecheap, Cloudflare), log into that provider's DNS panel and add the TXT record there.
4. Webflow does not send transactional store emails directly from your domain by default; these are typically handled by an integrated email provider. Check your Webflow Ecommerce settings and any connected email tools for their required SPF include: hostnames.
5. Combine all required include: entries into a single SPF TXT record (you can only have one SPF record per domain).
6. Verify with MXToolbox SPF Lookup.

What is missing spf?

SPF (Sender Policy Framework) is a DNS record — a single line of text you publish at your domain — that lists every mail server and service allowed to send email from your domain address. When someone receives an email claiming to be from you, their mail server looks up this record and checks whether the sending server is on your approved list. If there is no SPF record at all, there is nothing to check against, and your domain is completely open to impersonation. Think of it as a guest list for who is allowed to send email in your name.

Without an SPF record, criminals can forge your domain in the "From" address of phishing or spam emails — a technique called email spoofing — and your customers, suppliers, or partners may receive fraudulent messages that appear to come from your business. This directly harms customer trust and can expose you to legal liability. Beyond fraud risk, major email providers (Google, Microsoft, Yahoo) now treat domains without SPF as suspicious and are more likely to send your legitimate transactional emails — order confirmations, shipping notices, password resets — straight to spam, costing you sales and customer satisfaction. A missing SPF record also contributes to OWASP A05:2021 Security Misconfiguration findings, which can affect security audits and partner due-diligence reviews.
