How to Add DKIM Records in Wix

Step-by-step guide to add DKIM records for domains hosted on Wix. Learn how to configure DKIM for Google Workspace, Microsoft 365, and email services with Wix DNS.

Last updated: 2026-01-28

If your domain's DNS is managed through Wix, you can add DKIM records for your email services there. This guide shows you how to add DKIM records to Wix DNS for services like Google Workspace, Microsoft 365, and email marketing platforms.

Wix is your DNS provider—it hosts your DNS records. Your DKIM keys come from your email service. Wix doesn't generate DKIM keys; it publishes the records so mail servers can find them.

Before You Start

You'll need:

  • A Wix Premium plan (required for custom domains)
  • Your domain connected to Wix
  • The DKIM record details from your email service

Get your DKIM information from your email provider before starting.

Adding a DKIM TXT Record

Most email services use TXT records for DKIM.

1

Access Wix DNS settings

Log into your Wix account. Go to your Dashboard → Settings → Domains → select your domain → Manage DNS Records.

Or go directly to the Domains page and click Manage DNS.

2

Add a TXT record

Click + Add Record and select TXT.

3

Configure the TXT record

  • Host Name: Enter the selector and _domainkey. For example:
    • Google Workspace: google._domainkey
    • Zoho: zmail._domainkey
  • Value: Paste the full DKIM value from your email service (starts with v=DKIM1)
  • TTL: Leave as default (1 hour)
4

Save the record

Click Save.

Adding a DKIM CNAME Record

Some services like Microsoft 365 and Mailchimp use CNAME records.

1

Add a CNAME record

In Wix DNS settings, click + Add Record and select CNAME.

2

Configure the CNAME record

  • Host Name: Enter the selector and _domainkey. For example:
    • Microsoft 365: selector1._domainkey
    • Mailchimp: k1._domainkey
  • Points to: Enter the target your email service provided
  • TTL: Leave as default
3

Save the record

Click Save.

Verify Your Setup

After adding records, verify they're publicly accessible.

Wix DNS changes typically propagate within 30-60 minutes, sometimes up to 48 hours.

Common Email Services

Google Workspace

  • Type: TXT
  • Host Name: google._domainkey
  • Value: From Google Admin Console (starts with v=DKIM1; k=rsa; p=...)

Microsoft 365

Add two CNAME records:

Record 1:

  • Type: CNAME
  • Host Name: selector1._domainkey
  • Points to: selector1-yourdomain-com._domainkey.yourtenant.onmicrosoft.com

Record 2:

  • Type: CNAME
  • Host Name: selector2._domainkey
  • Points to: selector2-yourdomain-com._domainkey.yourtenant.onmicrosoft.com

Mailchimp

  • Type: CNAME
  • Host Name: k1._domainkey
  • Points to: dkim.mcsv.net

Zoho Mail

  • Type: TXT
  • Host Name: zmail._domainkey
  • Value: From Zoho Mail Admin Console

Common Issues and Solutions

"Record not found" error

Cause: DNS hasn't propagated or the record is misconfigured.

Solutions:

  • Wait 30-60 minutes and check again
  • Verify the Host Name field is correct (don't include your full domain—Wix adds it)
  • Check for typos in _domainkey

2048-bit key issues

Wix supports long TXT records, but if you encounter issues:

  • Verify the entire key was copied without truncation
  • Try without any line breaks in the value
  • As a last resort, try a 1024-bit key from your email provider

CNAME record won't save

Cause: Possible conflict with existing records or format issue.

Solutions:

  • Check for duplicate records
  • Ensure the target doesn't have a trailing period
  • Verify no spaces in the record values

When adding the Host Name field in Wix, don't include your full domain. Enter google._domainkey not google._domainkey.example.com. Wix adds the domain automatically.

Wix Inbox and Email

Wix Inbox (the built-in messaging system) and Wix email campaigns use Wix's own infrastructure. For emails sent through Wix:

  • Wix handles email authentication automatically
  • No additional DKIM setup is needed for Wix's native email features

For external email services (Google Workspace, business email, marketing platforms), you need to add DKIM records manually.

Wix Ascend Email Campaigns

If you use Wix Ascend for email marketing:

  • Wix manages DKIM signing for Ascend emails
  • Your domain should be verified within Ascend settings
  • Check Ascend's email settings to confirm domain authentication

Complete Your Email Authentication

After adding DKIM, configure SPF and DMARC:

SPF: Add a TXT record at your root domain (@) with your email providers. Check at spfrecordcheck.com.

DMARC: Add a TXT record at _dmarc with your policy. Check at dmarcrecordchecker.com.

Checking once is good. Monitoring continuously is better. The Email Deliverability Suite watches your SPF, DKIM, DMARC, and MX records daily and alerts you when something breaks.
