How accurate is Gamalogic batch email verifier?

The Gamalogic batch email verifier uses a proprietary algorithm for real-time email address validation. It begins with the SMTP pinging of the target domains’ MX records. However, there is a disadvantage to this advanced technology: it may alert the ISP provider and cause our server to be website communication with our server. As a result, because such blocks are a problem, we use advanced algorithms to prevent them. We improved the verification process by capturing all email addresses from cooperate emails configured under G-Suite and Office 356 services which make us the best email verifier in the market.

Why This Matters Beyond a Clean-Looking List

A validated list isn’t just tidier it directly affects whether your emails land in an inbox at all. Sending to a list with a high percentage of invalid or risky addresses increases your bounce rate, which email providers read as a signal that you might be a spammer. Over time, that lowers your sender reputation and can affect deliverability even for the good addresses on your list.

Validate email in google sheets rather than exporting to a separate tool means you can catch this before every send, without adding a step to your workflow. It’s the same reasoning behind checks like catch-all domain detection and disposable address filtering: the goal isn’t just “is this formatted like an email,” it’s “will this email actually get delivered.”

New users get a 7-day trial with 500 free credits, no credit card required. After the trial, credits can be purchased based on your list size see pricing for details.

How is this different from a basic formula check in Google Sheets?

A formula like ISEMAIL only checks formatting whether the text looks like an email. It can’t tell you if the domain exists or if the mailbox is real. Real-time validation goes further with domain and SMTP-level checks, catching dead or fake addresses a formula would miss.

Yes. The add-on supports batch verification directly inside your sheet select your email column, click Start Validate, and results populate in a new column once processing completes.

Does the add-on detect disposable or role-based email addresses?

Yes. Beyond basic syntax checks, it flags disposable/temporary addresses and other risk indicators so you can clean your list before sending a campaign.

Will I lose my original data if something goes wrong during validation?

No. The add-on writes results into a new column next to your existing email list your original data stays untouched in the sheet.
