Email deliverability checker.
Enter your store domain to check SPF, DKIM, DMARC and MX in seconds — the four records that decide whether your Shopify emails land in the inbox or the spam folder.
Common questions
What does this email deliverability checker test?
It queries public DNS for your SPF record, DMARC policy, DKIM keys on the most common selectors, and MX records, then scores how likely your mail is to reach the inbox.
Why do my Shopify emails go to spam?
Most often because SPF, DKIM or DMARC are missing or misconfigured on the sending domain. Since February 2024 Gmail and Yahoo require all three from bulk senders.
Is the checker free?
Yes. There is no signup and no email required — enter a domain and get the report instantly.
