Email Domain Verification

To protect our platform from abuse, we verify your email domain before sending a verification code.

Why does this check exist?

Opensolr is a cloud search platform used by real businesses. To keep the service reliable for everyone, we require email addresses to come from legitimate, established domains — the same way banks, SaaS platforms, and enterprise services do. Throwaway or newly registered domains are a strong indicator of abuse.

What does our system check?

MX Records

The domain must have valid mail exchange (MX) records — meaning it is technically configured to receive email.

Email Authentication

The domain should have SPF and DMARC DNS records — industry-standard anti-spoofing policies used by all serious organisations.

Domain Age

Very recently registered domains are a red flag for fraud. Established domains give confidence that the email is from a real organisation.

Mail Infrastructure

The domain's mail server should be self-hosted or routed through a well-known reputable provider such as Google, Microsoft, or Zoho.

Web Presence

The domain should have a working website. A registered domain with no web presence is unusual for a legitimate business.

What should I use instead?

Use a business email on an established domain, or a well-known personal email provider:

Gmail Outlook Yahoo Mail Fastmail Zoho Mail iCloud Your company domain

Think this is a mistake?

Our scoring system can occasionally flag legitimate domains that are new or have incomplete DNS configuration. If your domain is being incorrectly rejected, email support@opensolr.com and we will review it manually.
