Incorrect DNS records can have several negative impacts on your email marketing efforts:
Emails Marked as Spam: Without proper authentication, your emails are more likely to be flagged as spam by receiving servers. Reduced Deliverability: Incorrect DNS settings can cause emails to bounce back, reducing your overall deliverability rate. Poor Sender Reputation: Consistently failing to authenticate your emails can harm your sender reputation, making it harder to reach inboxes in the future.
