TXT Record (SPF, DKIM, DMARC)

In one sentenceDNS records that hold text, used to prove you own a domain and to protect your email from being faked or landing in spam.

What it means

Services ask you to add a TXT record to verify domain ownership (Google, Microsoft, email tools). TXT records also carry the three email security standards:

SPF lists which services may send email as your domain. DKIM adds a digital signature to your emails so receivers can verify them. DMARC tells receivers what to do with emails that fail those checks and where to send reports.

Gmail, Yahoo and Microsoft now expect proper SPF, DKIM and DMARC from anyone sending email in bulk, so they matter a lot for AI-powered outreach.

How to use it

• Before an AI tool or automation sends email from your domain, add the SPF and DKIM records the sending service gives you.
• Your domain should have only one SPF record. Add new senders inside it instead of creating a second one.
• Send automated or high-volume email from a subdomain (like mail.yourdomain.com) to protect your main domain's reputation.
