"How to Search for Legitimate Email Addresses" matching MCP tools:

• subscribe_to_digestA

  NetGrant — Canadian fundingA

  Subscribe the user to a FREE weekly email digest of Canadian funding opportunities matching a saved search (keywords + region). Each week they get 8–10 grants, newest first, falling back to the strongest current matches when nothing new landed. WHEN TO CALL: - The user, after a search, says yes to ongoing alerts, or asks to be notified / kept updated / emailed about new grants in their niche. - Only after they have explicitly agreed and given an email address — never subscribe someone proactively or without consent. HOW TO CALL: - Pre-fill "keywords" and "region" from the search you just ran so the digest matches what they were looking at (e.g. keywords "cleantech", region "BC"). Keep keywords to a short phrase, not a sentence. - "region" must be a province code (ON, BC, QC, AB, MB, SK, NS, NB, NL, PE, YT, NT, NU) or "Federal", or omit it for all-of-Canada. - Ask the user for their email; do not guess it. Never invent, test with, or fill in a placeholder address (e.g. user@example.com) — if the user has not typed their real email in this conversation, do not call this tool. Undeliverable addresses are rejected with "Invalid email". WHAT HAPPENS: - We send a one-click confirmation email (double opt-in). The user is NOT subscribed until they click it. Tell them to check their inbox. - If they were already confirmed, nothing is re-sent. Returns JSON: { ok: boolean, status: "confirmation_sent" | "already_subscribed" }. Confirm to the user what they signed up for (e.g. "weekly BC cleantech grants — check your email to confirm").

• reply_to_emailA

  AgentiSendA

  Purpose: reply to one received email. Sets In-Reply-To and References so the conversation threads, and runs every send check a new send runs. NOT for: a new conversation (send_email), or reading the original (get_received_email). The recipient is the first Reply-To address, else the first From address; any other addresses in those headers are left off, so pass them as cc if they should get the reply. from defaults to the address that received it. Returns: the outbound message id and its status. Delivery happens after; get_email has the outcome. Refusals are the same as send_email: domain_not_verified, suppressed_recipient, agent_budget_exceeded. Addresses ending in @simulator.agentisend.com cost nothing. Sending twice is sending twice: pass an idempotency_key and a retry returns the first message id instead of a second email.

• list_accountsA

  Local MCPA

  Lists Mail.app email accounts WITH each account's email addresses, server_name and type. type is whatever Mail reports — imap | pop | iCloud | smtp | unknown — and Mail's scripting dictionary has NO Exchange value, so Exchange (EWS) accounts always come back as unknown, flagged with type_undetermined: true and a type_note; for those read the mailbox through the m365_* tools (or outlook_diagnose) instead of routing by type. Slower — queries Mail directly. For just the account NAMES (to pass to list_emails(account=...)), prefer list_email_accounts: it's faster (cached, no Mail lock).

• walletlink_estimate_listA

  walletlink.socialA

  A dry run over a list of addresses: how many are in the index, how many were checked and found bare, how many have never been seen, and the band a resolve would bill inside. Counts only, no identities. Use it to decide whether a list is worth resolving, and which tool to spend on. COST: free on the match meter, always, even at zero balance. It weighs the rate window exactly like resolving the same list (one request-unit per address), so it previews a batch at the batch’s own pace. Minimum 10 distinct addresses, because the counts are aggregates by design; the ceiling is your plan’s batch ceiling. Reading the band: low is exact for resolving this list now (the addresses already holding an X handle or a Farcaster account). high adds never-checked addresses at the measured overall rate; a background job resolves those against live sources, a plain resolve does not. Match rates differ several-fold by chain; the coverage tool and /v1/stats carry the measured per-chain table.

• email_searchA

  animaA

  Search messages by content. Fulltext mode (default) substring-matches subject/body/addresses of EMAIL messages and returns `{items, pagination}` with cursor paging. Semantic mode ranks by vector-embedding similarity and returns `{results}` scored 0-1 — each result spans ANY channel (check the `channel` field) and includes the message id for email_get / email_thread_get follow-ups.

  ConnectorOAuth

• send_emailA

  AgentiSendA

  Purpose: send one email now, or at a time you name. Takes one recipient or a list. Each To, CC and BCC recipient counts as one email. NOT for: checking whether a send would work (preflight_email), sending many different messages at once (send_batch), or asking a person first (request_approval). Returns: the message id and its status, immediately. Delivery happens after; get_email has the outcome. Refusals name the gate and the cure: validation_error lists the bad fields, domain_not_verified points at verify_domain, suppressed_recipient says the address asked not to be contacted. Addresses ending in @simulator.agentisend.com cost nothing, reach nobody, and work before any domain is verified. from onboarding@agentisend.com delivers real mail only to this account's member sign-in addresses, 20 per UTC day, with no cc, bcc, attachments, tracking, or extra headers. Sending twice is sending twice: pass an idempotency_key and a retry returns the first message id instead of a second email.

• create_contactA

  MisarMail MCP ServerA

  Add a single contact. Adding a contact records consent to email them — only add addresses that opted in, or the send will damage sender reputation and may breach CAN-SPAM/GDPR.

• get_contact_infoA

  Symbols of Wealth StudioA

  Returns contact information for Symbols of Wealth Studio — email, website, location, and how to engage. Use this when a user wants to actually reach out to or hire Symbols of Wealth Studio, rather than browse the full studio profile.

• get_contact_infoA

  symbols-of-wealth-studioA

• list_email_accountsA

  Local MCPA

  Lists all Mail.app account NAMES (fast — cached, no Mail lock). This is the preferred way to get account names: call it first to discover them, then use list_emails(account=name) to fetch messages from a specific account. If you also need each account's email addresses or type (imap/pop/iCloud), use list_accounts instead.

• outreach_add_contactsA

  rankparse-mcpA

  Add contacts with per-contact email copy to a campaign (max 100 per call, 500 per campaign, one contact per domain). Works on a draft campaign AND on an already-launched one, which is how you top a live campaign up with fresh prospects. Each contact needs a researched, real email address (never guess addresses) plus a personalized subject and plain-text body (subject ≤500 chars, body ≤10,000). Write like a human: plain punctuation, and NEVER use em-dashes in subjects or bodies. Subjects must be 2-5 words that read like a note from a colleague and reference their content (e.g. "your AI tools guide"): never sales words like exclusive, lifetime, revenue, or deal. Internationalized (non-ASCII) domains must be given in punycode (xn--) form. Returns how many were added and which were skipped (invalid email, duplicate domain/email, copy too long, campaign full, already_contacted = this person was emailed in an earlier campaign). Contacts added to a launched campaign sit inert until you call outreach_launch_campaign again.

• verify_listA

  Qualisend Email VerificationA

  Verify a large list of up to 1000 email addresses. This runs ASYNCHRONOUSLY: it creates ONE bulk job, returns a job_id immediately, and the mailbox probes run in the background. Poll get_verification with the job_id for progress and a result summary (counts by verdict). Consumes 1 credit per address. For lists larger than 1000, use the Qualisend dashboard or bulk API.

• verify_emailsA

  MisarReach MCP ServerA

  Check whether email addresses are deliverable, one or up to 20 at a time. Run this before a send to protect sender reputation — bouncing a campaign off dead addresses is what gets a domain blocked. Pass either `email` for one or `emails` for a batch, not both. CONSUMES VERIFICATION CREDITS per address checked, so a 20-address batch costs 20. Requires an API key. Returns a deliverability verdict per address; 'undeliverable' is a successful result, not an error. Nothing is sent to the addresses.

• find_company_emailsA

  PeopleSearch.imA

  Given a company domain or name, return the contactable role-based email addresses discovered for that organization (such as contact@, sales@, support@), each with a confidence level. Use this for reaching a company inbox, not a specific named person (for a named person use find_people or find_linkedin_profile). Spends 2 credits, refunded if none are found.

• add_site_access_emailsA

  TuqoA

  Add many addresses to the email allowlist in one call, separated by newlines, commas or semicolons. Duplicates and existing entries are skipped, invalid ones are returned separately: partial success is normal. Labels are not set here (a comma would split them): use set_site_access_email_label afterwards.

  ConnectorOAuth

• remove_site_access_emailsA

  TuqoA

  Remove several addresses from the email allowlist, or clear it with all:true. Access ends immediately for everyone listed, including visitors currently viewing, and cannot be undone except by re-adding. Requires confirm:true: show the user who will be removed first.

• agent_deleteA

  animaA

  Delete an agent by ID. Use this to remove deprecated or compromised agents that should no longer send messages. Cascades to attached addresses, email identities, and phone identities.

• send_emailA

  MailcheerA

  Sends a single (transactional) email to one or more addresses. The sender must belong to a verified domain of the workspace — call get_account to see which ones. An address suppressed for a bounce, a complaint or by hand fails the entire call, with its reason. An unsubscribed address still gets an individual email (a reply, an invoice, an appointment); a newsletter or a prospecting email must carry `unsubscribe_url`, and is then refused to an unsubscribed address. At most 50 addresses in all, to, cc and bcc together. Every address (to, cc, bcc) counts against the plan's monthly quota: past it, the call is refused (`quota_exceeded`) with the figures and the reset date — do not retry before that date. The email is sent immediately: this action cannot be undone.

• send_campaignA

  MailcheerA

  ⚠️ IRREVERSIBLE. Locks the recipient list and triggers sending to ALL active subscribers in the workspace — or, with `to`, only to the requested addresses that are active subscribers (never an unsubscribed or suppressed address). A sent email cannot be recalled. First call preview_campaign_send with the same parameters, then ask the person for explicit confirmation, telling them how many people will receive the message. Messages go out progressively; get_campaign_stats tracks progress.
