How to Implement Backup Authentication Methods?

Implementing backup authentication methods can seem daunting, but it is a crucial step in safeguarding your email marketing efforts. Here are some steps to get started:
Set Up 2FA
Most email service providers offer two-factor authentication. Enable it in your account settings and choose the method of receiving your secondary code (SMS, email, or an authentication app).
Configure DKIM and SPF Records
To set up DKIM and SPF, you will need to update your domain's DNS records. This typically involves adding a TXT record that contains your DKIM public key and another TXT record for SPF that lists the IP addresses authorized to send emails on behalf of your domain.
Implement DMARC
Create a DMARC policy by adding a TXT record to your DNS settings. This record will specify how your emails should be handled if they fail SPF or DKIM checks and where to send reports of such failures.
