Overview
Check My Leads — Email and Phone Verification for Google Sheets

Check My Leads is a Google Sheets add-on that helps users verify email addresses and validate phone numbers directly from a spreadsheet.

The add-on is designed for users who maintain contact or prospect lists and want additional information about email addresses and phone numbers before conducting outreach.

Features
Email Verification

Check email addresses and receive a verification status such as:

Valid — The email address passed the available verification checks.

Invalid — The email address failed one or more verification checks, such as email syntax, domain, or mailbox validation.

Accept All (Catch-All) — The domain accepts email without confirming individual mailboxes. These addresses may still result in delivery failures.

Risky — The email address passed validation but has characteristics that may present increased deliverability risk.

Unknown — Verification could not determine a definitive result. Retrying the address later may produce a different result.

Email verification does not guarantee email delivery. Delivery can be affected by factors outside the verification process.

Phone Number Validation
Validate phone numbers and receive information about the number, including its validation status and available phone type information.

Phone types may include:

Cell — Number identified as a mobile/wireless number.

Landline — Number identified as a landline.

VOIP — Number identified as Voice over IP.

Phone validation and phone-type information do not guarantee that a particular call or SMS message will be successfully delivered.
