SMS and MMS are available as a paid add-on for texts inside sequences and one-off sends, but Sequenzy is not a dedicated omnichannel or two-way SMS platform - Landing pages are for focused signup and offer capture, not full website CMS use - Commerce integrations are available, but Sequenzy is strongest for SaaS, product-led, and lifecycle email programs rather than broad retail merchandising suites - Sequenzy is strongest for SaaS and product-led businesses, not e-commerce merchandising ## Official Links -

Split your audience, measure results, and send the winner automatically. - Subject Line Testing: Small changes to subject lines can double your open rate. Test variations and let the data decide. - Content Testing: Test different layouts, copy, or offers. See which version drives more clicks and conversions. - Automatic Winner Selection: Set your test criteria and sample size. We pick the winner and send it to the rest of your list automatically. - Statistical Confidence: We calculate statistical significance so you know when results are real, not random noise. How it works: 1. Create your variations: Write two or more versions of your email. Test subject lines, content, CTAs, or anything else. 2. Set test parameters: Choose your sample size and winning metric. Usually 10-20% of your list for the test, opens or clicks to pick the winner. 3. Send the test: We split your test audience evenly across variations and send them simultaneously. 4. Winner gets sent: After your test period, we automatically send the winning version to the rest of your list. ### Analytics URL: https://www.sequenzy.com/features/analytics Track opens, clicks, and conversions.

No waiting for reports to update. - Subscriber Insights: See who's engaging with your emails. Click on any metric to see individual subscribers. - Geographic Data: See where your subscribers are.

How it works: 1. Enable Auto UTM in Tracking: Turn on Add UTMs to links from your website tracking settings and define default source, medium, campaign, content, or term values. 2. Compose your email normally: Add text links, buttons, image links, product links, and CTA links without manually building tracking parameters into each URL. 3. Preview the final tracked links: In the editor, Sequenzy shows the final URL for auto-tagged links so you can verify exactly what will be sent. 4.

Your team works it in the dashboard; your AI agents work it through the API, CLI, and MCP. - Your Own Inbox Address: Every workspace gets an address like inbox+id@inbound.sequenzy.com, or the same address on your verified domain. Give it to people, services, or other agents. - Replies Land in the Same Thread: Replies to campaigns, sequences, and transactional email arrive with the email that caused them, and follow-ups stay in one conversation. - Built for AI Agents: List unread conversations, read full threads with attachments, reply, forward, and close through the public API, the CLI, or MCP tools. - Reply, Forward, and Attach: Answer from your verified sender profiles, forward a message to a teammate, attach files, and add internal notes the contact never sees. How it works: 1. Turn on receiving: Switch on Inbox in Settings. Replies route back through a trackable reply-to address, and your inbox address starts accepting mail. 2. Share your inbox address: Use it anywhere you would give out an email address. Mail sent to it opens a new conversation, or joins the thread it answers. 3. Work the conversations: Filter by unread, open, or closed. Reply, forward, add notes, mark read or unread, and close conversations one at a time or in bulk. 4. Hand it to an agent: Connect Claude, Cursor, or another agent through MCP or the CLI so it can triage the inbox and draft or send replies for you. Docs: https://docs.sequenzy.com/concepts/reply-tracking ### Localization URL: https://www.sequenzy.com/features/localization Manage localized email variants, preview the right language, and send each subscriber the version that matches their locale. - Per-Locale Email Variants: Store localized subjects, preview text, and email blocks alongside the primary email. - Subscriber Locale Resolution: Use subscriber attributes to decide which localization each recipient should receive. - Safe Fallbacks: Fall back to the primary language when a specific localization is missing or still syncing. - Preview and Test by Locale: Preview recipient-specific localized content and send test emails for the resolved language.

Now agents run the newsletter workflow end to end. - 8 hrs/mo: Manual newsletter work automated - $45/mo: SendGrid bill eliminated - 98.7%: Deliverability after the switch > Sequenzy is fully observable, so agents can just set everything up. With SendGrid there's no way for agents to observe the outcome, so every change would eat my hours. > - Elvis Sun, Founder, PressPulse & Medialyst ## Agent Quickstart Source: https://www.sequenzy.com/agents.md ### agents.md Machine-readable quickstart for agents working with Sequenzy. #### Discovery - Agent auth guide: https://www.sequenzy.com/auth.md - API catalog: https://www.sequenzy.com/.well-known/api-catalog - OpenAPI spec: https://api.sequenzy.com/openapi.yaml - MCP server card: https://www.sequenzy.com/.well-known/mcp/server-card.json - Agent skills: https://www.sequenzy.com/.well-known/agent-skills/index.json - LLM facts: https://www.sequenzy.com/llms.txt #### API And MCP Access Use https://www.sequenzy.com/auth.md for user-approved API/MCP access. It describes the `service_auth` claim flow, where the agent registers with the user's email, asks the user to approve the code in a Sequenzy-owned browser page, polls for a bearer credential, then calls the API or MCP server with `Authorization: Bearer `. Do not treat `auth.md` as dashboard account signup. It is for agent API/MCP credentials. #### Dashboard Signup Normal dashboard account signup is a user-facing app flow at https://www.sequenzy.com/sign-up. It uses Sequenzy's Better Auth routes under `/api/auth/*` and creates a dashboard account. #### First Company After Dashboard Signup When operating inside an authenticated dashboard session with tRPC access, create the first company with the direct procedure input body: ```json { "noWebsite": true, "name": "Prelaunch App" } ``` Do not wrap mutation input in a `json` property: ```json { "json": { "noWebsite": true, "name": "Prelaunch App" } } ``` After `companies.create` succeeds: 1. Call `companies.syncSession` so the current dashboard session sees the new company. 2. Verify with `companies.list`. 3. Inspect the created company with `companies.getById`. Prefer public API or MCP workflows for durable integrations. Dashboard tRPC is for authenticated dashboard-session automation only. #### How agents start - Free tier available: sign up at https://www.sequenzy.com/sign-up. 2,500 emails/month, unlimited contacts, API/MCP/CLI included. No credit card. - Self-serve API key generation: create a key in dashboard Settings → API keys after signup, or follow https://www.sequenzy.com/auth.md. Do not fill out a contact-sales form. - Sandbox / test environment: https://www.sequenzy.com/sandbox. The free plan is the live sandbox. - Zero-auth access: https://www.sequenzy.com/llms.txt, https://www.sequenzy.com/agents.md, https://www.sequenzy.com/auth.md, https://www.sequenzy.com/.well-known/api-catalog, https://api.sequenzy.com/openapi.yaml, and GET https://api.sequenzy.com/health require no authentication. ## Agent Auth Source: https://www.sequenzy.com/auth.md ### auth.md Sequenzy supports agentic registration for the Sequenzy API and MCP server through the user-claimed `service_auth` flow: discover, register with the user's email, have the user confirm the code in a Sequenzy-owned browser page, poll for an access token, then call the API with a bearer credential. Resource server: `https://api.sequenzy.com/v1/mcp` Authorization server: `https://www.sequenzy.com` #### Step 1 - Discover Fetch Protected Resource Metadata first. If a 401 response includes `WWW-Authenticate: Bearer resource_metadata="..."`, use that URL. Otherwise use: ```http GET https://api.sequenzy.com/.well-known/oauth-protected-resource ``` Response fields to read: `resource`, `resource_name`, `resource_logo_uri`, `authorization_servers`, `scopes_supported`, and `bearer_methods_supported`. Then fetch OAuth Authorization Server metadata: ```http GET https://www.sequenzy.com/.well-known/oauth-authorization-server ``` Read `issuer`, `token_endpoint`, `revocation_endpoint`, `grant_types_supported`, and the `agent_auth` block. Prefer `service_auth` for new integrations; the `user_claimed` fields remain available for older device-code clients: ```json { "skill": "https://www.sequenzy.com/auth.md", "identity_endpoint": "https://www.sequenzy.com/agent/identity", "claim_endpoint": "https://www.sequenzy.com/agent/identity/claim", "events_endpoint": "https://www.sequenzy.com/agent/event/notify", "register_uri": "https://api.sequenzy.com/api/device-auth/initiate", "claim_uri": "https://www.sequenzy.com/setup/auth", "revocation_uri": "https://www.sequenzy.com/api/oauth/revoke", "identity_types_supported": [ "service_auth", "user_claimed" ], "identity_assertion": { "assertion_types_supported": [] }, "service_auth": { "credential_types_supported": [ "api_key" ], "claim_grant_type": "urn:workos:agent-auth:grant-type:claim", "credential_transport": "bearer_header" }, "user_claimed": { "flow": "device_code", "credential_types_supported": [ "api_key" ], "verification_uri": "https://www.sequenzy.com/setup/auth", "poll_uri": "https://api.sequenzy.com/api/device-auth/poll", "credential_transport": "bearer_header" }, "events_supported": [] } ``` #### Step 2 - Pick a method Sequenzy currently prefers `service_auth`. - Use `service_auth` when you have the user's Sequenzy account email. - Existing device-code clients may continue to use `user_claimed`. - Do not use `anonymous`; Sequenzy returns `anonymous_not_enabled`. - Do not use `identity_assertion`; Sequenzy does not currently accept ID-JAG assertions. Supported ID-JAG assertion types: `urn:ietf:params:oauth:token-type:id-jag` is not enabled. Requested scope: `mcp` Credential transport: `Authorization: Bearer ` #### Current limitations Sequenzy is not fully agent-friendly yet. This auth.md file helps agents discover registration and obtain a user-approved bearer credential, and MCP/CLI cover many common email workflows. Some setup, billing, destructive account actions, advanced configuration, and final send decisions may still require dashboard use or explicit human review. #### Step 3 - Register ```http POST https://www.sequenzy.com/agent/identity Content-Type: application/json { "type": "service_auth", "login_hint": "user@example.com" } ``` Success response: ```json { "registration_id": "reg_...", "registration_type": "service_auth", "claim_url": "https://www.sequenzy.com/agent/identity/claim", "claim_token": "clm_...", "claim_token_expires": "2026-05-21T17:31:25.994Z", "post_claim_scopes": ["mcp"], "claim": { "user_code": "123456", "expires_in": 900, "verification_uri": "https://www.sequenzy.com/setup/auth", "interval": 5 } } ``` No `identity_assertion` is issued. The user must complete the claim ceremony before the agent can receive a bearer credential. #### Step 4 - Claim ceremony Surface `claim.verification_uri` and `claim.user_code` to the user in one message. The user opens the link, signs in to Sequenzy as `login_hint`, reviews the request, and approves it in Sequenzy. The code is entered on the Sequenzy page, not back into the agent. Poll the token endpoint with the claim grant no faster than `claim.interval` seconds: ```http POST https://www.sequenzy.com/api/oauth/token Content-Type: application/x-www-form-urlencoded grant_type=urn:workos:agent-auth:grant-type:claim &claim_token= ``` While waiting: ```json { "error": "authorization_pending" } ``` On success: ```json { "access_token": "seq_user_...", "token_type": "Bearer", "scope": "mcp" } ``` #### Step 5 - Use the access token ```http Authorization: Bearer ``` The response carries no `expires_in` and no `refresh_token`: the credential does not expire on a timer. Store it and keep using it. Do not treat the connection as unauthenticated after any elapsed time, and do not start a new authorization flow unless a request actually fails with `401`. The user can revoke the credential at https://www.sequenzy.com/api/oauth/revoke or from Account → API Keys.
