Email reputation refers to the assessment of an email sender's trustworthiness and credibility by internet service providers (ISPs) and email receivers. It is an essential factor that determines whether an email will end up in the recipient's inbox, spam folder, or get rejected altogether.
The best way to achieve email reputation is by authenticating your emails.
This can be done using authentication methods, such as Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), to verify the authenticity of your emails and prevent email spoofing and phishing attacks.
Sender Policy Framework (SPF)
Sender Policy Framework (SPF) is an email authentication method used to prevent email spoofing and protect against email fraud. It is a widely adopted industry standard that helps verify the authenticity of the sender's domain in an email message. SPF allows the domain owner to specify which mail servers are authorized to send emails on behalf of their domain.
So, we suggest that you please add this as a TXT record in the control panel of the website where your nameservers are currently pointing to.

DomainKeys Identified Mail (DKIM)
DomainKeys Identified Mail (DKIM) is an email authentication method that allows the recipient's mail server to verify the authenticity of an email message and confirm that it was not altered during transit. DKIM uses cryptographic signatures to verify the integrity of the email and ensure that it was sent by the legitimate domain owner.
