How to Set Up DNS to Send Emails with mySMTP and SMTP.dk

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’s how to do it step by step:

Step 1: 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 2: Add These Records

You’ll 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're 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:This email address is being protected from spambots. You need JavaScript enabled to view it.

Step 3: Wait for DNS to Update

DNS changes can take up to 24 hours to fully work, but often it’s much faster.

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.
