More free tools for website, domain, and email diagnostics

We’ve expanded our free tools for website, domain, and email diagnostics. We’ve added email configuration checks and DNS record generators. You can now find all our tools in one section and use them without signing up.

If your emails land in spam or fail to arrive, start with the email configuration check. It checks your domain’s DNS records, whether mail server IP addresses appear on blacklists, and encryption support. The results show you which settings need attention and where to change them. It does not access your mailbox, read messages, or send test emails.

We’ve also added individual checks for MX, SPF, DKIM, and DMARC records, plus a tool to check IP addresses against blacklists. If you need an SPF or DMARC record, you can prepare it with a generator, then add it to DNS. These tools help you find configuration errors, but do not guarantee inbox placement.

In the same section, you can check an SSL certificate for a website or mail server and see when it expires. You’ll also find a WHOIS domain lookup and a certificate signing request (CSR) generator.

We’re continuing to develop new free tools so you can handle more tasks for your website, domain, and email yourself.
