1 min read

In this tutorial, you’ll learn how to connect and verify an external domain and validate a professional sender email to use MailinBoss for email marketing – without changing your domain’s nameservers.
For a full visual walkthrough, watch the video at the top of this article.

Tutorial: Domain and Sender Email Setup in MailinBoss

This process is divided into two main parts:

  1. Domain connection and DNS validation
  2. Sender email verification

Before You Start

  • Your domain can remain hosted with any external provider.
  • You do not need to change nameservers unless you want full domain migration.
  • The sender email must already exist (MailinBoss does not create email inboxes).

1. Adding an External Domain in MailinBoss

  1. Go to Tools > MailinBoss.
  2. Access Settings.
  3. Create your Company if you haven’t done so yet.
  4. Open Domains and click New Domain.
  5. Select External Domain.
  6. Enter your domain name (without www or https).
  7. Select the company you created.
  8. Click Next to generate DNS records.

MailinBoss will generate the required DNS records:

  • DKIM (TXT)
  • SPF (TXT)
  • DMARC (TXT)
  • CNAME

2. Adding DNS Records at Your Domain Provider

Log in to the DNS manager of your domain provider.

DKIM Record (TXT)

  1. Create a new TXT record.
  2. Copy the Host/Name provided by MailinBoss.
  3. Paste the Value exactly as shown.
  4. Save the record.

SPF Record (TXT)

SPF is usually an existing record.

  1. Locate the existing SPF record (TXT).
  2. Edit the record.
  3. Add the MailinBoss include value inside the existing SPF, separated by a space.
  4. The include must be placed before ~all or -all.
  5. Save the changes.

This step is critical for proper email delivery.

DMARC Record (TXT)

  1. Create a new TXT record.
  2. Use _dmarc as the host.
  3. Paste the value provided by MailinBoss.
  4. Replace the default email with a real email from your domain, for example:
    • abuse@yourdomain.com
  5. Save the record.

CNAME Record

  1. Create a new CNAME record.
  2. Use the host provided (for example, MB).
  3. Paste the value shown by MailinBoss.
  4. Save the record.

3. DNS Propagation

  • DNS propagation may take anywhere from 20 minutes up to 48 hours.
  • Once propagation is complete, MailinBoss will confirm that the domain is verified.

4. Verifying the Sender Email

  1. Add the professional sender email you want to use.
  2. The email must already exist in your email provider.
  3. MailinBoss will send a verification code to that email.
  4. Check your inbox and spam folder.
  5. Enter the verification code to complete validation.
  6. Once verified, the sender email will be ready for use.

Conclusion

After completing these steps:

  • Your domain will be fully connected.
  • Your sender email will be verified.
  • You’ll be able to send email marketing campaigns through MailinBoss with proper authentication and deliverability.
