Common Mistakes and How to Avoid Them
When updating SPF and DKIM records, it's important to avoid common mistakes: SPF: Ensure you do not exceed the DNS lookup limit. Use the "include" mechanism wisely.
DKIM: Make sure the public key is correctly added to the DNS records and matches the selector used in your email headers.
Use
online tools like MXToolbox to check SPF records.
Send a test email to services like MailTester to verify DKIM signatures.
Impact on Email Marketing Campaigns
Properly configured SPF and DKIM records significantly improve your email marketing efforts by ensuring higher email deliverability and reducing the chances of your emails being marked as spam. This leads to better
open rates and higher
engagement with your audience.
