# DNS Settings Quick Explainer

> Set up SPF, DKIM, and DMARC DNS records for your domain to authorize mySMTP sending and improve email deliverability. Step-by-step guide included.

To send emails reliably through **mySMTP and SMTP.dk**, you need to add some **DNS records** to your domain. This tells the internet that **mySMTP/SMTP.dk** is allowed to send emails for you — helping your emails land in inboxes instead of spam. Especially for the big free mail operators MAGY (MicrosoftAppleGmailYahoo) its now mandatory for delivery

Here is how to do it step by step:

<Steps>
  <Step title="Log in to Your Domain Provider">
    Go to the website where you bought your domain (like GoDaddy, Namecheap, ONE.com etc.), and log in.

    Look for a section called:

    * **DNS Settings**
    * **Manage DNS**
    * **DNS Records**
  </Step>

  <Step title="Add These Records">
    You will need to add 3 types of records: **SPF**, **DKIM**, and **DMARC**.

    **1. SPF Record**

    This allows mySMTP/SMTP.dk to send emails for your domain.

    * **Type:** TXT
    * **Name / Host:** @
    * **Value:** `v=spf1 include:_spf.mysmtp.com ~all`
    * If existing record is already there, add this string: **include:\_spf.mysmtp.com**

    **2. DKIM Record**

    This adds a digital signature to your emails to prove they are really from you.

    * **Type:** TXT
    * **Name / Host:** mysmtp.\_domainkey
    * **Value:** The 2048 key generated: xxxxxxx

    **3. DMARC Record**

    This tells email servers what to do if SPF or DKIM fails.

    * **Type:** TXT
    * **Name / Host:** \_dmarc
    * **Value:** `v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com`
    * Free DMARC wizard: [https://dmarcian.com/dmarc-record-wizard/](https://dmarcian.com/dmarc-record-wizard/)
  </Step>

  <Step title="Wait for DNS to Update">
    DNS changes can take up to **24 hours** to fully work, but often it is much faster.
  </Step>
</Steps>

**Done!**

Once the records are added and DNS has updated, your domain is ready to send emails through **mySMTP/SMTP.dk** with better deliverability and fewer issues.
