SPF DKIM DMARC Security Checker is an easy-to-use browser-based tool that allows you to check SPF, DKIM and DMARC records for a selected domain in just a few seconds, see if your configuration protects against email address spoofing, and better understand why some messages end up in your inbox, others end up in spam, or are rejected by email servers.
What SPF DKIM DMARC Security Checker can do in practice
This the tool was designed for people who want to quickly and clearly check the email configuration for their domain, without having to manually enter commands into the console or jump between several different services. You enter the domain name, optionally add DKIM selectors, run the scan and after a while you get a summary that shows the status of SPF, DKIM and DMARC in one place.
SPF DKIM DMARC Security Checker performs DNS queries, reads text records associated with email and presents them in a readable report. You can see whether the domain has an SPF record, how the DMARC policy is configured, whether there are working DKIM records for selected selectors, and how these elements affect your domain's resistance to spoofing and spam. Everything is described in clear messages that can be easily communicated to the technical team or agency that helps with mail handling.
- Searches for the SPF record associated with the domain and shows its contents in its original form.
- Checks whether a DMARC record is configured for the domain and what the active policy is for the main domain and subdomains.
- Parses the specified DKIM selectors and tries to find the corresponding DNS records.
- Builds a concise summary that describes the overall level of protection against spoofing and misconfiguration.
How to work with the tool step by step
The SPF DKIM DMARC Security Checker interface is built to be understandable for administrators, marketing specialists and business owners who do not have to sit in the mail server console every day. The form consists of a field for the domain, a field for DKIM selectors and one switch that allows you to automatically scan popular selectors used by many e-mail service providers.
In practice, it looks like this: you enter, for example, the address of your company domain, add your own DKIM selectors if necessary, select the option to scan the most common selectors, and then click the button to start the scan. Once the tool is finished, you get a view divided into a summary, an SPF section, a DKIM section, a DMARC section, and a table with additional details, so you can quickly see what elements are already configured correctly and what needs refinement.
- You enter the domain for which you want to check SPF, DKIM and DMARC.
- Optionally, you add your own DKIM selectors, separated by commas or spaces if you are working with multiple keys.
- You can enable a switch that allows you to scan common DKIM selectors without manually typing their names.
- You run the analysis, and the tool presents the results in the form of a clear report with a summary and details.
Why you should check SPF, DKIM and DMARC for your domain
For many companies, configuring SPF, DKIM and DMARC is the invisible foundation of email security that runs in the background until everything is set correctly. The problem begins when the first messages start ending up in the spam folder, customers report that they did not receive important documents, or someone tries to send fake e-mails impersonating addresses in your domain. SPF DKIM DMARC Security Checker helps you spot potential errors and gaps in settings faster, before they translate into real deliverability and image problems.
Checking these three mechanisms in one place allows you to get a full picture of how mail servers see your domain. The SPF record tells you where you can send mail from, DKIM is responsible for cryptographic signatures of messages, and DMARC tells you what the recipient's server should do if something goes wrong. Seeing these elements side by side, in one report, is a huge help both when configuring from scratch and when reviewing existing settings for the purposes of a security audit or changing email providers.
Improving the deliverability of mailing campaigns
If you use newsletters and automatic e-mail campaigns, the correct configuration of SPF, DKIM and DMARC for the sender's domain is of great importance to whether messages reach the main inbox or are filtered by anti-spam systems. With SPF DKIM DMARC Security Checker, you can more quickly detect missing records or overly lenient policies that cause recipient servers to treat your email less trustily.
Protecting your brand against spoofing
Spoofing e-mail addresses from someone else's domain is a real problem in the world of phishing and online fraud. Proper DMARC settings, combined with consistent SPF and DKIM records, reduce the risk of someone sending a message that appears to come from your company. The tool's report shows whether your DMARC policy actually enforces rejection of suspicious messages or merely requests reporting, giving you a clear starting point for further optimization.
Cleaning up the configuration after changing the server or provider
When migrating e-mail to a new server, changing the hosting panel or implementing additional services, such as a newsletter system or external CRM, it is easy to get confused about which IP addresses and which servers have the right to send messages on behalf of the domain. The SPF DKIM DMARC scanner then helps you quickly check whether any old entries have been left in the configuration, whether new records have been added correctly and whether the DMARC policy takes into account the current shipping model.
How to use SPF DKIM DMARC Security Checker step by step
Using the tool is intuitive even for people who are just starting their adventure with email administration, and thanks to simple labels and messages you can quickly go from the first scan to the list of specific tasks to be performed in the DNS panel or with the hosting provider.
- Enter the domain name for which you want to check SPF, DKIM and DMARC, for example the corporate domain from which you send emails to customers.
- If you are using DKIM, enter the names of the selectors you are using in the selectors field, separated by commas or spaces, so that the tool can check them one by one.
- You can leave the automatic scanning of the most popular DKIM selectors enabled, which is especially convenient if you don't remember the exact names you set in your email provider's panel.
- Click the button to launch the scan and wait while the tool performs DNS queries for SPF, DKIM and DMARC, and then presents the results in the form of tables and short descriptions.
- Based on the summary, record details and comments regarding the level of spoofing protection, you can prepare a list of changes to be implemented, which you can then implement in the DNS panel or submit to the administrator.
What exactly does the SPF DKIM DMARC Security Checker report show
Once the scan is complete, the tool displays the results in several sections, so you can quickly take a look at your overall security status and, if necessary, drill down into individual records. You don't have to manually assemble information from several consoles and screenshots, because you have the entire SPF, DKIM and DMARC context in one summary.
