What you'll learn
An email domain checker is a tool to verify the validity and reputation of an email domain.
In 2024, nearly 322 brands worldwide were targeted in phishing attacks. And 1,800 Google accounts were under threat for spear phishing.
Alarming, right?
At the moment, someone could receive emails with your initials and brand name. It’s called ‘name and email spoofing’ in which attackers use your name and domain name to steal information from customers. To avoid becoming a victim, it’s best to use an email domain checker.
At Campaign Refinery, we take measures to protect your email domain from threats.
Currently, our email experts manually review all domains added to the platform. We’re also making domain checks a necessity for all our users. To increase safety measures, we’ve outlined the benefits of a domain email checker, how to check domain email health, use cases, and types of domain mail checkers.
What are the Benefits of Email Domain Checker
Whether you’re a company or an individual sending mass emails, your domain and sender reputation matter. If you’re regularly topping the spam charts, internet service providers (ISPs) will stop sending your emails to the recipients. In worse cases, you could be refrained from sending emails altogether.
That’s why it’s crucial to use an email domain health checker. Verifying if an email domain is valid involves a rigorous process: sender verification, checking blacklists, and analyzing records.
Even when everything seems good, your reputation can be affected by shared email lists, shared IP addresses, and higher bounce rates. Check email domain names and understand how an email domain checker works to prevent these issues.
How Does an Email Domain Tester Work?
To check email domain validity, it’s critical to use an email domain checker tool.
A valid email domain checker provides detailed information about your blocklists, MX records, SPF, DKIM, DMARC, and web reputation. Here are the steps involved:
1. DNS Look-up
DKIM is a record in DNS email records that protects the domain by guarding the domain’s authenticity and integrity. A DKIM record is a modified version of TXT records that are added to the DNS server on the sending domain. It’s possible to do this manually. However, we encourage using an authentication tool for email health check and better optimization.
2. Spam Blacklist Checks
The email validation tool scans your domain and mail server IP addresses against many DNS-based real-time blacklists (RBL) to check for discrepancies. If your domain is found on the blacklist, you can proceed to apply for a removal request or by using a spam email domain checker.
3. Check Mail Server Logs
Any unusual activity on one of your servers will subsequently reduce your deliverability rates and caution ISPs to flag your domain. Email domain security check tools prioritize this step to look out for patterns of email delivery issues or suspicious login attempts.
4. Diagnose Email Deliverability Rates
Another important aspect of email domain check is performance tracking. The authentication tool goes through email open rates, click-through rates, bounce rates, and spam complaints to understand your domain reputation.
5. Check Sending History
A rule of thumb is to regularly check email domain and send email sequences to your email marketing subscribers consistently. When you don’t, an ISP is alerted for inconsistent patterns. And when your email practices are constantly fluctuating, it could be flagged as spam.
Is Domain Authentication Mandatory at Campaign Refinery?
We use a rigid security process to protect the sender and recipients. In short, domain authentication is necessary for our clients – all our customers have 100% of the email volume signed with DKIM by default. While we watch over your email marketing efforts, we’d also like you to know the basics of domain validation.
Domain Email Health Check — Recognizing Spam
Your emails could end up in the spam list for many reasons, like lower domain reputation, sending spam-like content, and lower ISP reputation. But it certainly doesn’t have to be due to purchasing email lists.
At Campaign Refinery, we prohibit the use of purchased email lists and cold emailing under our Acceptable Use Policy. Also, with genuine email lists, we use an advanced email list-cleaning feature that increases deliverability rates. Our clients have successfully seen an upward 30% deliverability rate.
How to Check Email Domain for Blacklists
To get there, we recommend you use a domain name reputation check tool and check for blacklists frequently.
The health of your domain is a primary focus for many ESPs, especially us. We take a proactive approach to ensure your domain is valid and trustworthy so you can focus on the quality of varied types of email campaigns.
How to Increase the Health of Your Domain?
Several free tools offer email domain reputation checks. However, we recommend using the paid version or doing it manually.
To do it yourself, follow the steps below:
- Implement proper email authentication: As the first step, set up the SPF, DKIM, and DMARC records for your domain. This protects the domain from phishing attacks and identity theft.
- Manage bounce rates: Maintain consistent email list hygiene and distinguish between hard bounces (permanent failure) and soft bounces (temporary issues).
- Use double-opt-in: Sometimes, users are in a hurry and must provide the necessary information. For this reason, use the double opt-in method (email confirmation) to avail access to your email content.
- Provide unsubscribe options: If you want more open rates and fewer spam complaints, let the subscribers go when they want to. Use a one-click unsubscribe by adding the unsubscribe button at the top and bottom of your emails.
- Use a dedicated IP address: If you send email campaigns, it’s best to use your own IP address for better control and deliverability.
There are many ways an email domain verifier is used in marketing. Below, we’ve listed a few of the common use cases.
