How to Check Emails While You Browse: the SimpleVerifier Chrome Extension

The free SimpleVerifier Chrome extension finds the emails and phone numbers on the page you are viewing, checks them in your browser for typos, disposable domains and role addresses, and with a Google sign-in runs 50 live mailbox checks a month. It is for research: checking the handful of addresses in front of you before you copy them into a list. For a whole list, upload a CSV.

What it does

The extension page lists the features. In short:

Feature	Needs an account?
Find emails and phone numbers on the page	No
In-browser checks: syntax, typo suggestions, disposable and role addresses	No
Phone format check (country, line type, E.164 form, not a live line check)	No
Who hosts the site's email, and whether it publishes SPF and DMARC	No
50 live mailbox checks a month	Google sign-in
Copy or export a CSV	No

Step 1: find the addresses

Open a page, such as a team or contact page, and click Find on this page. The extension lists every address, mailto: and tel: link on it. It reads the page only when you click.

Step 2: read the free checks

Each address gets in-browser checks. A typo domain such as gmial.com is flagged, as are disposable domains and role addresses like info@. Nothing leaves your browser for these.

Step 3: run a live check on the ones that matter

Sign in with Google and run a live check on the addresses you pick. A live check asks the mail server whether the mailbox exists and returns valid, risky or invalid with a reason. See how to read a verification report. No message is sent; see does verification notify the person.

Step 4: take the list with you

Copy the list or export it as a CSV. If it grows into a real list, upload it on the verify page, where the first 100 checks are free with a Google sign-in, no card.

When to use it, and when not

• Use it when you are researching a company and want to know whether the address on its contact page is real before you copy it.
• Do not use it for a list of hundreds. A CSV upload does the same mailbox check across the whole file.
• Do not use it to guess addresses. For name and company, the email finder is on Pro.

Privacy

It sends only the addresses you choose to live-check to simpleverifier.com. Anonymous usage counts can be switched off in the popup. The extension privacy policy lists every permission.

Next step

Install it from the extension page, or run 100 free checks on a list. See pricing: Starter is $9 a month for 2,500 emails, packs start at $15 for 10,000 checks, and Pro is $39 a month with the first 100,000 checks a month at full speed, then slower, never cut off.
