MisarMail MCP Server

Get delivery and engagement analytics — sent, delivered, opened, clicked, bounced, and complained — for the account or one campaign, grouped by day/week/month.

Get a day/week/month breakdown of sent, delivered, opened, clicked, bounced, complained, replied, and unsubscribed — across every send medium (campaigns, inbox compose, API, MCP, SDKs, GraphQL, automations). The timeline counterpart to get_analytics's period totals.

Get one automation workflow in full: trigger, every step with its delay, and per-step completion stats.

Get full details for one campaign: content, audience segment, schedule, and delivery statistics (sent, opened, clicked, bounced, complained).

Get engagement score, engagement tier, and churn risk for one contact — or the lowest-engagement contacts across the list when contact_id is omitted. Use before a re-engagement campaign.

Get the account deliverability score (0–100) and letter grade (A–F) with the factors dragging it down. Start here when asked why emails are landing in spam.

Read the full content of a single email by ID, including headers, body, and attachments metadata. Side effect: marks the email as read.

Get one signup form including its fields, embed code, and redirect behaviour.

List submissions for a signup form, including the submitted field values and timestamps.

Get every message in one inbox conversation, oldest first, with sender and timestamps.

Get one integration's configuration, scopes, and last sync result.

Get one marketplace listing with its full preview, author, and install count.

Get newsletter monetization stats: paid subscribers, MRR, churn, and sponsorship revenue for the period.

Attribute ecommerce revenue to email — revenue per campaign, per contact, and average order value from tracked conversions.

Get IP/domain warm-up progress and today's remaining send capacity. Exceeding warm-up capacity on a new domain is the fastest way to get throttled or blocklisted.

Bulk-import up to 5,000 contacts in one call. By default, addresses that already exist are skipped rather than duplicated — pass update_existing: true to update them instead. Returns per-row results so you can see which rows were rejected and why.

List A/B tests with per-variant results and whether a winner has been selected yet.

List API keys on the account with their scopes and last-used time. Key secrets are never returned — only metadata.

List automation workflows (welcome series, re-engagement, drip sequences) with their trigger type and active state.

List email marketing campaigns with their status, audience size, and headline metrics. Filter by status to find drafts ready to send or campaigns still sending.

List contacts with their subscription status and engagement metrics. Filter by status to find unsubscribed or bounced addresses that should be excluded from sends.

List sending domains with verification status and their DKIM/SPF/DMARC records. Check here first when a send fails with an unverified-sender error.

List emails from a mailbox folder with optional full-text search across subject and body. Use this for reading the unified inbox; use list_campaigns for marketing sends.

List signup forms with their embed status and conversion counts.

List unified-inbox conversations (threads) with their status and detected intent. Use this for triage; use list_emails for individual messages in a folder.

List connected third-party integrations and their sync status.

Browse the MisarMail template marketplace for ready-made email and automation templates.

List emails captured by sandbox mode. Sandbox intercepts sends instead of delivering them — use it to verify templates and automations without emailing anyone.

List saved email templates with their variable placeholders, so you can pick one for a campaign or transactional send.

Authenticate with your MisarMail account via browser — no API key copy-paste needed. Opens the MisarMail authorization page where you review the requested permissions and click 'Authorize'. The API key is delivered straight back to this client and saved to ~/.misarmail/config.json.

Forget the locally stored MisarMail API key (~/.misarmail/config.json). Does not revoke the key server-side — delete it from mail.misar.io/developers to do that.

Render a template with sample variables and return the resulting HTML and subject. Use this to preview personalisation before sending anything.

Reply to an existing email thread. The sender address and threading headers are derived from the original message, so only the body is required.

Run a full deliverability audit across authentication (SPF/DKIM/DMARC), domain reputation, list hygiene, content signals, and blocklist status. Returns prioritized findings.

Select the winning variant and send it to the remaining audience. This triggers a real send to everyone who was held back — it cannot be undone.

Send a campaign now, or schedule it for a future time by passing scheduled_at. This delivers real email to real recipients and cannot be undone once sending starts — confirm the audience with get_campaign first.

Send a transactional email from a verified MisarMail account. `from.email` must match an email account you have already verified — use list_domains to check which sender domains are available. Returns the message ID and queue status.

Activate or pause an automation. Activating starts enrolling contacts and sending on the configured schedule.

Enable or disable an integration. Disabling stops all syncing but preserves the stored credentials.

Update an existing contact by email address, including changing subscription status. Setting status to unsubscribed immediately excludes them from every future campaign. Does not support tags, phone, company, or job title — the API has no fields for them.

Show the current MisarMail plan, how much of each quota is left, and what upgrading unlocks, with the link to upgrade. Call it any time — not only after hitting a limit. Reads only: it never changes the plan or takes payment; the user upgrades by following the link. On a local install, open=true also opens that link in the user's browser.

Validate an email address before sending: syntax, MX records, disposable-domain and role-account detection. Use this to protect sender reputation on imported lists.

Re-check a domain's DNS records and mark it verified if they resolve. Safe to retry — DNS propagation can take up to 48 hours.
