Instructions for Updating Your Domain's SPF Record to Work with INKY

To ensure emails processed by INKY pass SPF checks and maintain deliverability, you need to add INKY's SPF mechanism to your domain’s SPF record. Below are step-by-step instructions for updating your SPF record.

Step 1: Identify Your Current SPF Record

  1. Log in to your DNS management portal (usually provided by your domain registrar or hosting provider).

  2. Look for the DNS Records or DNS Settings section.

  3. Check if you already have a TXT record that starts with v=spf1.

    Example of an Existing SPF Record:

    v=spf1 include:spf.protection.outlook.com -all

Step 2: Update the SPF Record

  • If you already have an SPF record:
    Append the following INKY mechanism to it:

    exists:%{i}._spf.inkyphishfence.com

    Updated Example:

    v=spf1 include:spf.protection.outlook.com exists:%{i}._spf.inkyphishfence.com -all

  • If you do not have an SPF record:
    Create a new TXT record with the following value:

    v=spf1 exists:%{i}._spf.inkyphishfence.com -all

Step 3: Save Changes

  1. Save the updated record in your DNS management portal.

  2. Note that DNS changes may take up to 48 hours to propagate, but they typically update much faster.

Step 4: Test and Validate Your SPF Record

After making the changes, verify the correctness of your SPF record:

  1. Use an SPF validation tool (e.g., MXToolbox SPF Check).

  2. Confirm that your updated SPF record includes INKY’s mechanism and does not exceed SPF limits:

    • A maximum of 10 DNS lookups.

    • TXT record length under 255 characters.

Best Practices and Notes

  • Keep Only One SPF Record: Ensure your domain has a single SPF record. If there are multiple, merge them into one.

  • Test Before Finalizing: If you're uncertain, test changes in a staging or non-critical domain before applying them to production domains.

  • Monitor Email Deliverability: Regularly review email logs to ensure smooth delivery.
