Review recommended
The format works, but check the signals
alex@gmil.com
The format is valid, but one or more signals deserve review.
Domain structure
The domain gmil.com uses valid labels and a public-looking suffix.
Common provider typo
This may be a typo. Did you mean alex@gmail.com?
Disposable-domain signal
The domain is not in this tool's curated disposable-domain list.
Role-based address
The address does not use a commonly shared role name.
Plus alias
No plus-addressing alias was detected.
MX and mailbox status
Not checked. This private browser tool does not query DNS, contact a mail server, send email, or claim that the mailbox exists.
Use the result responsibly
Format checks are useful, but consent proves more
Clean obvious mistakes
Fix missing @ symbols, malformed domains, repeated dots, and common provider typos before saving the address.
Review quality signals
Shared role inboxes, disposable domains, and aliases may be intentional. Treat them as context, not automatic rejection rules.
Confirm mailbox control
When identity or consent matters, send a clear confirmation message and require the recipient to complete the opt-in.
Email address verifier FAQs
What is an email address verifier?
An email address verifier checks an address for formatting and data-quality problems. This browser tool finds practical syntax errors, common provider typos, role names, aliases, and selected disposable domains.
Can this tool confirm that an email mailbox exists?
No. It does not contact a mail server or send a message, so it cannot prove mailbox existence or deliverability. Many mail servers also hide that information to prevent abuse.
Does the verifier send or store the email address?
No. The checks run in your browser and the address is not submitted to DripAgent by this page.
What is a role-based email address?
A role-based address uses a shared name such as support, sales, info, or admin instead of one person. It may be valid, but multiple people can receive it and consent may be harder to attribute.
What does a plus sign in an email address mean?
Plus addressing adds a tag such as name+trial@example.com. Many providers deliver it to the base inbox, but support varies, so this tool reports the alias without treating it as an error.
