Email Validator
Check email syntax, domain spelling and mail servers
Note: This checks syntax, common domain typos, disposable providers and MX records — it cannot guarantee the mailbox actually exists. Only sending an email can confirm that.
Email Validator — Complete Guide & Instructions
MakeCard Email Validator runs four checks on any address: RFC-style syntax, common domain-typo detection (gmial.com → gmail.com), disposable-provider screening, and a live MX record lookup to confirm the domain can actually receive mail. A single verdict badge — Looks valid, Suspicious, or Invalid — summarizes the result with each check listed underneath. It is a fast first-line filter for signup lists and contact forms.
How to Use Email Validator
- 1 Type or paste the email address into the field.
- 2 Press Validate.
- 3 Read the verdict badge — Looks valid, Suspicious, or Invalid.
- 4 Review the individual checks: syntax, domain spelling, disposable provider, and MX records.
Key Features & Capabilities
- Syntax validation against the standard email format.
- Typo detection for common misspellings — gmial.com, hotmial.com, yaho.com and more, with a "did you mean" suggestion.
- Disposable/throwaway provider screening (mailinator, tempmail, 10minutemail and similar).
- Live MX record lookup confirms the domain has mail servers.
- Clear per-check pass/fail rows plus an overall verdict.
Supported Formats & Specifications
| Parameter | Specification |
|---|---|
| Checks | Syntax, domain typos, disposable providers, MX records |
| MX lookup | DNS-over-HTTPS query to Google Public DNS |
| Verdicts | Looks valid, Suspicious, Invalid |
Practical Everyday Use Cases
- Cleaning a signup or newsletter list before sending.
- Catching typos like gmial.com in customer contact forms.
- Filtering throwaway addresses from a registration list.
- Verifying a vendor or client email before an important message.
Pro Tips for Best Results
- A "Looks valid" result means the domain can receive mail — it cannot prove the specific mailbox exists; only sending can confirm that.
- Treat Suspicious results as a prompt to double-check spelling with the owner.
- Disposable addresses in a signup list usually indicate fake registrations.
Common Problems & Solutions
The domain may use a provider without standard MX records (rare) or the MX lookup was blocked — the typo and disposable checks still passed, so verify manually.
No online tool can prove a mailbox exists without sending mail — SMTP probing is unreliable and often blocked, which is why the tool stops at MX level.
Privacy & Security
100% Client-Side Execution
Syntax, typo, and disposable checks run locally; only the domain part is queried against Google Public DNS to look up MX records. The full address is never sent to MakeCard servers or stored.
Frequently Asked Questions
Everything you need to know about using Email Validator
Paste it and press Validate — the tool checks the syntax, looks for domain typos, screens disposable providers, and confirms the domain has working mail servers.
Only partially — MX records prove the domain accepts email, but whether the exact mailbox exists can only be confirmed by sending (and watching for a bounce).
A temporary throwaway address from providers like mailinator or tempmail — often used for fake signups. This tool flags known disposable domains.
It is a common typo of gmail.com — the validator suggests the likely intended domain so you can correct it.
