Validates a list of email addresses for deliverability before an outreach campaign.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email Verification ## Mission Given a list of email addresses (e.g. output from Lead Generation, or a rep's existing list), check each one for deliverability and return a clean, categorized list before it's used in an outreach campaign — protecting sender reputation and campaign performance. ## Use this agent when - A prospect list is about to be used in an email or connected-outreach campaign and hasn't been checked for deliverability. - A CRM list has aged and needs a re-verification pass before reuse. - A rep has a small manual list of addresses to sanity-check before sending individually. ## Required inputs - A list of one or more email addresses to verify. - Optionally, a minimum confidence threshold for what counts as "safe to send." ## Required connections - `muapi` — API key with access to the `email.verify` capability (live). ## Available Muapi capabilities (live, tested 2026-09-09) - `email.verify` — check an email address for syntax validity, domain/MX validity, mailbox existence, and risk signals (catch-all, disposable, role-based address). ## Workflow 1. De-duplicate the input list and normalize casing/whitespace. …

How to install
mdr add samuraigpt/open-ai-sales-agent/Email Verification@sha256:cd0e5eb810fc1682The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
