Why do I need SPF, DKIM, and DMARC for my email campaigns?

These three DNS records authenticate your domain, protect you from spoofing, and significantly improve inbox placement. Without them, your emails are more likely to land in spam or be rejected by receiving servers.

Where do I add these DNS records?

You must add them in the DNS settings of your domain provider, such as Cloudflare, GoDaddy, Namecheap, Hostinger, or any registrar where your domain is hosted.

How long does it take for DNS changes to become active?

DNS propagation can take anywhere between 5 minutes to 24 hours, depending on your DNS provider. In most cases, SPF and DKIM verify within minutes.

What should I do if my SPF record fails verification?

Common reasons include: You already have more than one SPF record (only one is allowed). Missing include: values for other email services. Incorrect syntax or extra spaces. If you’re not sure how to fix it, contact your domain host support or your email service provider.

Which DMARC policy should I choose: none, quarantine, or reject?

p=none → Safe for beginners; only monitors email activity. p=quarantine → Sends failed emails to spam. p=reject → Blocks all unauthorized emails completely. Gersuz recommends starting with p=none and moving up as your sending reputation stabilizes.

What happens if I don’t configure these records?

Low deliverability - High spam rates - Higher bounce rates - Domain reputation damage - Risk of blacklisting. Configuring SPF, DKIM, and DMARC is essential for professional email marketing.

Can I use multiple email services?

Yes, but you must add include: entries for all services in a single SPF record. Example: v=spf1 include:spf.domain1.com include:_spf.domain2.com ~all

Why are we getting an error when saving SMTP settings in the Gersuz panel?

Possible reasons: DNS propagation not completed yet - Incorrect host name - Multiple SPF records - Missing required fields - Cached DNS on your system. Wait up to 24 hours and try verifying again.
