What this server can do

54 functions, named and described by the server itself. Parameter names are shown because they say more about what a function does than its name usually does.

add_domain(domain)

Add a sending domain and return the DNS records to publish. The domain cannot send until those records are live and verify_domain succeeds. Required: domain.

archive_email(id)

Move an email to the archive folder. Reversible — the message is not deleted. Required: id.

categorize_inbox_emails(email_ids)

Run AI categorisation over a batch of inbox emails to label intent and priority. Consumes AI credits — pass only the emails you actually need triaged. Required: email_ids.

check_dmarc(domain)

Check live SPF, DKIM, and DMARC DNS records for a domain and report alignment problems with the exact record to publish. Works for any domain, not only your own. Required: domain.

clear_sandbox

Delete every captured sandbox email. Affects only intercepted test messages, never real sent mail.

configure_inbound_domain(domain, subdomain, webhook_url)

Configure inbound email routing for a subdomain so replies land in the MisarMail unified inbox. Returns the MX record to publish. Required: domain, subdomain.

create_ab_test(type, variants, campaign_id, winner_metric, sample_percentage)

Create an A/B test on a campaign with two or more variants. A sample percentage is sent first; the winner goes to the remainder once selected. Required: campaign_id, type, variants.

create_automation(name, steps, active, trigger, trigger_config)

Create an automation workflow from a trigger and an ordered list of steps. Created paused by default — call toggle_automation to activate once the steps are reviewed. Required: name, trigger.

create_campaign(html, name, tags, text, subject, reply_to, from_name, from_email, segment_id, template_id, scheduled_at)

Create a new email marketing campaign as a draft. Creating never sends — call send_campaign separately once the content and audience are confirmed. Required: name, subject, from_email.

create_contact(tags, email, phone, source, company, job_title, last_name, first_name, custom_fields)

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. Required: email.

create_landing_page(name, slug, tags, cta_text, headline, subheadline)

Create a hosted landing page with an email capture form. Returns the public URL; subscribers flow straight into your contact list. Required: name, headline.

create_template(html, name, text, type, subject, variables)

Create a reusable email template. Use {{variable}} placeholders for personalisation — they are substituted at send time and previewable via render_template. Required: name, subject, html.

generate_report(date_to, date_from, report_type)

Generate a structured analytics report over a date range. Report types: campaign_performance, engagement_funnel, cohort_analysis, and send_time_heatmap (best hour/day to send). Required: report_type.

generate_subject_lines(tone, count, topic, audience)

Generate AI subject-line variants for a campaign topic, optionally tuned to a tone and audience. Good input for create_ab_test. Required: topic.

get_analytics(period, end_date, group_by, start_date, campaign_id)

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

get_automation(automation_id)

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

get_campaign(campaign_id)

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

get_contact_score(contact_id)

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_deliverability_score

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.

get_email(id)

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

get_form(form_id)

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

get_form_submissions(page, limit, form_id)

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

get_inbox_conversation_messages(conversation_id)

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

get_integration(integration_id)

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

get_marketplace_item(item_id)

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

get_monetization_stats(period)

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

get_revenue_attribution(period, campaign_id)

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

get_warmup_status

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.

import_contacts(contacts, update_existing)

Bulk-import up to 5,000 contacts in one call. Existing addresses are updated rather than duplicated. Returns per-row results so you can see which rows were rejected and why. Required: contacts.

list_ab_tests(page, type, limit)

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

list_api_keys

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

list_automations(page, limit, status)

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

list_campaigns(page, limit, status)

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(page, limit, search, status)

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_domains(page, limit)

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(limit, folder, search)

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_forms(page, limit, status)

List signup forms with their embed status and conversion counts.

list_inbox_conversations(q, limit, intent, offset, status, channel)

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_integrations(page, limit)

List connected third-party integrations and their sync status.

list_marketplace_items(page, limit, search, category)

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

list_sandbox_sends

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

list_templates(page, type, limit)

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

render_template(variables, template_id)

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

reply_to_email(html, text, email_id)

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

run_deliverability_audit

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

select_ab_test_winner(metric, test_id, winner_variant)

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. Required: test_id, winner_variant.

send_campaign(campaign_id, scheduled_at)

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. Required: campaign_id.

send_email(cc, to, bcc, from, html, tags, text, subject, alias_id, metadata, reply_to, idempotency_key)

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. Required: from, to, subject.

toggle_automation(active, automation_id)

Activate or pause an automation. Activating starts enrolling contacts and sending on the configured schedule. Required: automation_id, active.

toggle_integration(enabled, integration_id)

Enable or disable an integration. Disabling stops all syncing but preserves the stored credentials. Required: integration_id, enabled.

update_contact(tags, email, phone, status, company, job_title, last_name, first_name, custom_fields)

Update an existing contact by email address, including changing subscription status. Setting status to unsubscribed immediately excludes them from every future campaign. Required: email.

upgrade(open, plan)

Show the current MisarMail plan, how much of each quota is left, and what upgrading unlocks. Call it any time — not only after hitting a limit. Set open=true to open the checkout page in the default browser.

validate_email(email)

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

verify_domain(domain_id)

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. Required: domain_id.

Signals

These are separate measurements of different things. They are deliberately not combined into one score, because a popularity number that mixes website traffic with saves and stars cannot be checked or acted on.
