Achieving high Email Deliverability, maintaining a strong Sender Reputation, and preventing your messages from landing in Spam Folders all begin with the correct configuration of your SMTP account, DNS records, and Sending Limits.
The Gersuz Email Marketing Platform includes several built-in protections and validation tools that help ensure your campaigns reach your subscribers’ inboxes safely and effectively.
1.Mandatory DNS Configuration Check (SPF, DKIM, DMARC)
When a user sets up an SMTP Sending Account, Gersuz automatically analyzes the domain’s DNS records.
If one of the three critical DNS Authentication Records (SPF, DKIM, or DMARC) is missing or incorrectly configured, the system warns the user immediately.
These records directly impact:
- Spam rate
- Inbox placement rate
- Domain reputation
- Email authentication accuracy
A Domain Without Proper DNS Records has a much higher chance of having emails flagged as spam or rejected by receiving servers.
A Domain With Correct DNS Records significantly improves inbox placement, email trustworthiness, and overall sender score.
⚠️ Before Sending Any Emails via Gersuz, users must confirm that their DNS records are correctly configured.
💡Below is an example of a proper SPF, DKIM, and DMARC setup (example template – you can customize this in the final page):
SPF: v=spf1 include:your-smtp-provider.com -all
DKIM: (Generated DKIM public key provided by your SMTP service)
DMARC: v=DMARC1; p=none; rua=mailto:dmarc-reports@yourdomain.com
