Gmail and Yahoo Sender Rules: What Wedding Venues Need to Set Up
What do Gmail and Yahoo require from venues sending email?
Since February 2024, Gmail and Yahoo require every sender to authenticate their email. At minimum your domain needs SPF or DKIM, a valid sending setup, and a low spam-complaint rate. Senders of large volumes (around 5,000 or more messages a day to Gmail) must also have SPF, DKIM and a DMARC record, align the "From" domain, and offer one-click unsubscribe on marketing emails. For a venue, the practical answer is: publish SPF, enable DKIM, and add a DMARC record for your domain.
Detailed Forensic Analysis
Why this matters to a venue. Quotes, contracts, tour confirmations and replies to couples all come from your domain. Gmail and Yahoo now check that mail claiming to be from your domain is really authorized by you. Mail that fails these checks is more likely to land in spam or be rejected.
SPF lists who may send for you. SPF is a TXT record on your domain listing the services allowed to send as you: for example Google Workspace or Microsoft 365, your CRM, and your newsletter tool. A domain may only publish one SPF record, so every service must be combined into it.
DKIM signs your messages. DKIM adds a cryptographic signature to each message. You switch it on inside each sending service (Google Workspace, Microsoft 365, HoneyBook, Mailchimp and so on), and they give you a DNS record to publish.
DMARC tells receivers what to do. DMARC is a TXT record at _dmarc.yourdomain.com. Start with a monitoring policy such as "v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com", review the reports for a few weeks to confirm every legitimate service passes, then consider moving to p=quarantine.
The CRM trap. Many venues send proposals from a CRM "as" their own domain. If that CRM is not included in SPF and has no DKIM set up for your domain, those emails can fail authentication even though your normal mailbox works fine. Check each tool that sends as your domain.
How to check. Look up your domain's TXT records with your domain host or a DNS lookup tool, or run the free VenueGuard check, which reports whether SPF, DMARC and MX records were found. If a lookup cannot be completed we say "Not measured" rather than guessing.
