How to Verify Maileroo Domains Without Breaking Your Existing Business Email

Quick Answer: When verifying a domain in Maileroo that is already connected to Google Workspace, Microsoft 365, or a private mail server, you must ignore Maileroo's MX and DMARC recommendations. Only edit your existing SPF to include Maileroo, and add the new DKIM and CNAME tracking records.

When you sign up for a bulk email delivery service like Maileroo (our recommended SMTP provider for NewslettersMaker), their onboarding wizard gives you a list of DNS records to add. If you are starting a brand new domain from scratch, those instructions are fine.

But if you already have a functioning business email address (like hello@yourdomain.com hosted on Google Workspace, Microsoft 365, or a private server), blindly following Maileroo's default instructions will cause a disaster. Adding their MX records will break your incoming email, and adding their DMARC record will conflict with your existing strict security policies.

Here is your exact, step-by-step action plan to verify your Maileroo domain safely without breaking your existing mail flow.

1. The Merge (Edit your existing SPF)

Your SPF record tells the world which servers are allowed to send email on your behalf. You can only have one SPF record per domain. Maileroo tells you to add a new one, but you must merge theirs into yours instead.

If you use Google Workspace, you currently have this TXT record in your DNS:

v=spf1 include:_spf.google.com ~all

Edit that existing record and change the value to include Maileroo as well:

v=spf1 include:_spf.google.com include:_spf.maileroo.com ~all

(If you use a different email provider, just insert include:_spf.maileroo.com right before the ~all in your existing record.)

2. The Additions (Create 2 New Records)

Maileroo requires two completely new records to sign your emails securely (DKIM) and track link clicks. Note that Maileroo's dashboard sometimes displays confusing hostnames (like mta._domainkey.yourdomain.com). In most DNS providers (like Cloudflare or GoDaddy), you only need to enter the short name.

Add New Record #1 (DKIM)

Type: TXT
Name/Host: mta._domainkey
Value: (Copy the long v=DKIM1... string directly from your Maileroo dashboard)

Add New Record #2 (Custom Tracking)

Type: CNAME
Name/Host: click
Value: click.maileroo.net

3. What to Ignore (Skip these entirely)

This is the most critical step. Maileroo will show you MX and DMARC records on their setup page. Ignore them completely.

Ignore the MX Records: Maileroo handles your outgoing newsletters. Google/Microsoft handles your incoming mail. Keep your incoming mail flowing to your normal inbox. Maileroo will still verify your domain successfully even if you skip their MX records.
Ignore the DMARC Record: If your domain already has a DMARC record set up (e.g., v=DMARC1; p=quarantine;...), do not add another one. If you add Maileroo's DMARC record on top of your existing one, the two records will conflict, causing catastrophic delivery failures across the board. Keep your existing one!

Once you make these specific changes, wait 5 to 10 minutes for DNS propagation, then click Verify in Maileroo. Your domain will activate perfectly in Maileroo, and your primary business email will remain fully protected and operational.
