What are SPF, DKIM, and DMARC in plain English?

Three settings that live in your domain and together prove an email is really from you. With them in place, mail providers trust your messages. Without them, they treat your mail as possibly forged and route it to spam.

Why are my emails suddenly going to spam?

Often a provider tightened its rules. Google and Yahoo began requiring proper authentication in 2024. A new sending tool that is not authorized can also trigger it. Missing SPF, DKIM, or DMARC is the usual root cause.

Can I fix email deliverability myself?

Yes, if you are comfortable editing your domain's DNS records. Your email provider has step-by-step guides. If DNS is not something you want to touch, it is a quick job for someone technical to set all three in one sitting.

Why Is My Business Email Going to Spam?

Short answer

Usually because your domain is missing three settings that prove your email is really from you: SPF, DKIM, and DMARC. Without them, mail providers treat your messages as suspicious. They are one-time technical fixes, and once they are in place your email is far more likely to reach the inbox.

The three settings that build trust

You do not need to memorize these. You just need them set up correctly once. Here is what each one actually does, in plain English.

SPF: Lists which servers are allowed to send email for your domain, so other people cannot forge your address.
DKIM: Adds a hidden signature to every message that proves it really came from you and was not tampered with along the way.
DMARC: Tells receiving servers what to do with mail that fails those checks, and reports back who is sending as you.

How to tell yours might be off

You do not need to read DNS records to spot the warning signs. Any of these is a hint something is missing:

Your emails often land in a customer's spam or promotions folder.
Invoices, receipts, or appointment reminders quietly go missing.
You send from your own domain but were never asked to set up SPF, DKIM, or DMARC.
A newsletter or booking tool sends "on your behalf" and you never verified your domain with it.

If you are not sure whether these are set up, they probably are not. It is worth ten minutes to check before it costs you a sale.

What to do about it

All three live in your domain's DNS settings. Your email provider, like Google Workspace or Microsoft 365, has step-by-step guides, and someone technical can usually add all three in one sitting. If editing DNS records is not something you want to do yourself, this is exactly the kind of thing Klutch can check and fix for you.
