Guide on setting up the DNS records you have to set up for each domain: MX, SPF, DKIM, and DMARC.

Updated this week

Setting up MX, SPF, DKIM, DMARC, and forwarding are crucial steps in this process. You need all four records for your email account to function well. Here's a simple guide to help you get started.

Note: For Done-For-You or Pre-warmed domains from Instantly, the DNS records will be configured automatically.


Set up MX Record

MX Records is known for directing emails to you, without them no emails will arrive. Setting up the MX Record is critical - you should refer to your email provider's official documentation for the latest information.

  • To set up your MX Record in your Google Workspace, click here.

  • To set up your MX Record in Microsoft Office 365, click here.


Set up SPF record

SPF Record specifies authorized domains to send emails. It's a protocol that helps email servers verify that the sender of an email is who they claim to be. This helps reduce spam and phishing attempts, and it can improve your email deliverability.

  • To set up your SPF record in Google Workspace, click here.

  • To set up your SPF record in Microsoft Office 365, click here.


Set up DKIM record

DKIM Record adds a signature to emails, making them easier to trace and preventing spoofing.

  • To set up your DKIM record in Google Workspace, click here.

  • To set up your DKIM record in Microsoft Office 365, click here.


Set up DMARC record

DMARC Record authenticates emails, letting the world know they were sent from a legitimate source. To set up your DMARC, you may use this in different ways.

  • To set up your DMARC record in Google Workspace, click here.

  • To set up your DMARC record in Microsoft Office 365, click here.

  • Or choose to use a third-party DMARC provider from Postmark.

Note: Please configure DKIM and SPF before configuring DMARC.

DKIM and SPF should be authenticating messages for at least 48 hours before turning on DMARC.


How do I test DNS records?

You can click Test domain setup in your Instantly Email Accounts dashboard to verify if your DNS records are set up properly.

You may also use third-party tools to test your DNS records.


Set up Domain Forwarding

Setting up the forwarding is optional which means that it forwards the new domains to your main domain. This can be done in your Domain Settings Provider.

  • To set up forwarding for GoDaddy domains, please follow this guide.

  • To set up forwarding for Google domains, please follow this guide.

To set up forwarding for Done-For-You/Pre-warmed domains purchased from Instantly, please go to the billing page --> Email accounts & Domains, select the domains, and update or add the forwarding domain.
