Short answer: if your quotes, invoices or website form notifications land in spam, it’s almost always because your domain isn’t authenticated. Gmail, Outlook and Yahoo check three DNS records: SPF (who can send for your domain), DKIM (a signature proving the email wasn’t altered) and DMARC (what to do if something doesn’t match). With all three set up correctly, your emails are far more likely to reach the inbox.
Many businesses think “nobody contacts us through the website”. Actually they do: the form sends the notification, but it lands in spam or gets lost. Quotes go the same way: the customer never sees them and the business thinks they lost interest.
Why your emails go to spam
- No SPF, DKIM or DMARC on your domain. Since 2024 Gmail and Yahoo, and since 2025 Outlook, require authentication from bulk senders, and ask every sender for at least SPF or DKIM.
- Your website sends from a made-up address. By default WordPress sends notifications without authentication, from addresses like “wordpress@yourdomain”.
- Shared server on a blacklist. If another site on your server sends spam, it can affect you.
- Duplicate or broken records. Two SPF records, or one with too many lookups, break authentication.
How to check if it’s happening to you
- Send an email from your domain to a Gmail account and see if it lands in spam.
- In Gmail, open it, three-dot menu, “Show original”: check whether SPF, DKIM and DMARC say PASS.
- Use a test like Mail Tester, which scores your email from 1 to 10.
- Fill in your own website form and check that the notification arrives.
Our own proof. SEGEN’s business email (info@segen.tech) scores 10/10 on Mail Tester (October 2026 test), with valid SPF, DKIM and DMARC. We take every client’s domain through the same test.
What we do at SEGEN
We audit your domain, set up SPF, DKIM and DMARC correctly, connect your website notifications to authenticated sending and give you the before-and-after test. Nobody can promise every email will always reach the inbox, because content and reputation matter too; what we do is remove the technical problems that send you to spam. We work with businesses in Miami, the US and Latin America. See our email deliverability service or write to us.
Frequently asked questions
What are SPF, DKIM and DMARC?
They are three records in your domain's DNS. SPF says which servers can send on your behalf, DKIM signs each email to prove it wasn't altered, and DMARC says what to do with emails that fail those checks.
Why don't my website form emails arrive?
Usually because the website sends without authentication, from an address your domain doesn't authorize. It's fixed by connecting sending to your real mailbox with SPF, DKIM and DMARC.
Do you guarantee emails won't go to spam?
Nobody can guarantee that, because content and reputation also matter. We do guarantee correct authentication and show you the before-and-after test.
Does it work with cPanel email, Google Workspace or Microsoft 365?
Yes. The records are adjusted to your email provider.
