How to Set Up Email Authentication in WEDOS
What is email authentication
Email authentication is a set of DNS records — SPF, DKIM, and DMARC — that protect your domain from being used to send fraudulent emails. Each record serves a different purpose, and together they form a complete protection. For a detailed overview, see SPF, DKIM, and DMARC — Complete Email Authentication Guide.
You can set up all three records in the WEDOS DNS management. Log in to the WEDOS customer center and click DNS in the top menu.

Click your domain name, then select DNS Records in the left menu. From there, you will add all three records following the guides below.
| Order | Record | Name | Step-by-step guide |
|---|---|---|---|
| 1. | SPF | (empty — applies to the main domain) | Set up SPF in WEDOS → |
| 2. | DKIM | {selector}._domainkey |
Add DKIM in WEDOS → |
| 3. | DMARC | _dmarc |
Set up DMARC in WEDOS → |
SPF record
An SPF record specifies which servers are allowed to send emails on behalf of your domain. In WEDOS, you add it as a TXT record with an empty name — it applies to the main domain. The record value depends on which services you use to send emails (WEDOS Mail, Google Workspace, Microsoft 365, etc.).

DKIM record
A DKIM record contains a public key that recipients use to verify that an email was not altered in transit. In WEDOS, you add it as a TXT record with the name {selector}._domainkey. You get the selector and public key from your email service settings (Google Workspace, Microsoft 365, WEDOS Mail, etc.).

DMARC record
A DMARC record tells recipients what to do with emails that fail SPF and DKIM checks — whether to deliver them, send them to spam, or reject them. In WEDOS, you add it as a TXT record with the name _dmarc. We recommend setting it up after SPF and DKIM are in place.

Next steps
Once all three records are in place, verify the complete configuration of your domain. Enter your domain in the SPFmonitor domain analysis tool — it checks SPF, DKIM, and DMARC at once and flags any issues.
If you send emails from multiple services, verify the settings for each one. The guide on setting up SPF, DKIM and DMARC at Czech hosting providers can help you find the correct values.
