Domain Authentication - Online Help | Zoho Campaigns

Domain Authentication

Email marketing is constantly subjected to spamming and spoofing affecting the business in the long term. We as marketers have often found our inboxes filled with spam messages. Most of those email senders seem familiar to us but are actually not who they say they are. Spammers make use of a legit sender's identity to flood us with unwanted sometimes inappropriate emails. Thus making us want to block all such emails from invading our inbox again. In the process, unintentionally blocking even genuine emails because of the similarity they share with spam emails.

Domain authentication is a method used by all email marketers to protect their mail boxes from such malicious attacks. They provide validation mechanisms that verify an email right from its point of origin. This mechanism improves the email sender's reputation and increases the trust we will have on their emails.

Why should I authenticate my email domain?

Let's take a look at the various reasons as to why you should authenticate your domain.
  1. Improves your email deliverability.
  2. Prevents misuse of your domain.
  3. Increases the chances of your email to land directly in the inbox.
  4. Makes you an authentic email sender improving your reputation in the market.

What if I don't authenticate my sender domain

If you send emails from an unauthenticated domain, mailbox providers display to your contacts that your emails are from an unauthorized source. This is to warn your contacts that the email could be spam. Most mailbox providers view unauthenticated sender domains as suspicious, and differentiate them from authenticated senders to help their users avoid getting spoofed.

Gmail differentiates an unverified sender in the sender address part of an email with a "via", as shown in the image below. Here, is the sending source (Zoho Campaigns) and is the actual email sender domain. Gmail has warned its users to avoid engaging with this email.
