MyEmailVerifier

Verify email deliverability without leaving Claude.

MyEmailVerifier checks whether an email address can actually receive mail. Each verification runs syntax validation, domain and MX record lookups, and a live SMTP mailbox check, then reports whether the address is safe to send to — along with flags for disposable domains, role-based accounts, catch-all domains, free consumer providers, and greylisting.

Ask Claude to check a single address, paste in a list of up to ten at once, or ask how many verification credits you have left. Results come back as a readable summary and as structured data, so Claude can reason over them — filtering a list down to deliverable addresses, or explaining why a particular address is risky.

Typical uses: cleaning a mailing list before a campaign, validating signups, checking leads before outreach, and cutting bounce rates to protect sender reputation.

The connector is read-only. It cannot modify or delete anything in your account. Verification credits are drawn from your existing MyEmailVerifier balance, with no additional charge for connector use. Free accounts include starter credits and need no credit card.

Connect once with your MyEmailVerifier API key. The key is validated live, encrypted into your access token, and never written to disk or a database. Email addresses you verify are passed straight to the MyEmailVerifier API and are not logged or retained.
