Tools
- Create Tag
Create a reusable subscriber tag definition; Sequenzy normalizes its name to lowercase and replaces spaces with hyphens.
- Delete Tagdestructive
Permanently delete a non-system tag definition and remove it from every subscriber. Do not use this on system tags; Sequenzy also rejects tags referenced by sequences.
- Get Email Metrics
Return workspace-wide email delivery and engagement totals and rates for a sliding window or custom range, optionally filtered by email type or mailbox provider. Mailbox-provider filtering reports replies as 0 and omits commerce forecasts.
- Get Subscriber
Retrieve one subscriber by email with list memberships, sequence enrollments, notes, engagement totals, and recent activity.
- List Campaigns
Discover campaigns in the connected workspace, optionally filtered by delivery status or label, without scheduling or sending them.
- List Sequences
Discover automation sequences and inspect whether they accept new enrollments or process existing ones, without activating or enrolling anyone.
- List Subscriber Lists
Return the reusable subscriber lists available for audience filtering and membership workflows.
- List Subscribers
Search and filter subscribers in the connected workspace, returning one stable cursor page for audience review or export.
- List Tags
Return reusable subscriber tag definitions, including which tags are protected system tags.
- List Templates
Discover reusable email templates and campaign-backed email bodies by label, returning one page with localization metadata.
Setup
Setup guide
- 11. In Switchy, open the Project where you want to use Sequenzy and click the integrations panel. 2. Select 'Add MCP' and choose Sequenzy from the catalog. 3. You'll be prompted to paste an API key — generate one in your Sequenzy workspace under Settings > API Keys with read and write permissions. 4. Paste the key into Switchy and click 'Connect'. 5. Switchy will confirm the connection and show you the ten available tools. 6. To test, type '@Sequenzy list the subscriber lists in my workspace' in a new message — you should see your audience segments returned in seconds. 7. From now on, @mention Sequenzy in any message to invoke its tools; the AI will choose the right one based on your request.
What teammates see: by default, memories from Sequenzy are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@sequenzy show me all subscribers who joined in the last 7 days and are tagged as 'trial-user'
Found 23 subscribers matching your criteria. All joined between January 15–22, 2025, and carry the 'trial-user' tag. The list includes email addresses, signup dates, current sequence enrollments (12 are in the 'Trial Onboarding' sequence), and engagement totals. Three subscribers have opened at least one email; the remainder have not yet engaged. This is a single cursor page; if your workspace has more matching records, you'll need to request the next page explicitly.
This example demonstrates list-filtering and tag-based segmentation, core to audience management in Sequenzy. The MCP returns one page at a time, so large result sets require pagination. You'll need API_KEY auth with read access to subscribers and tags.
@sequenzy create a new tag called 'Webinar Attendee' so I can segment people who registered for our Q1 event
Tag 'webinar-attendee' created successfully. Sequenzy normalized the name to lowercase and replaced the space with a hyphen, as documented. The tag is now available for manual assignment via the UI or bulk tagging through the API. No subscribers are tagged yet; you'll need a separate workflow to apply it to your webinar registrants. System tags (like 'unsubscribed' or 'bounced') cannot be created or deleted through this tool.
This write example shows tag creation, a foundational step before segmenting or automating workflows. Be aware that Sequenzy enforces naming conventions automatically, and deleting a tag later will strip it from all subscribers—use caution if the tag is referenced by active sequences.
@sequenzy pull email metrics for the last 30 days and summarize which mailbox providers have the worst engagement rates
Over the past 30 days, your workspace sent 14,320 emails with a 22.1% open rate and 3.4% click rate overall. Breaking down by mailbox provider: Gmail accounts opened 24.3% of messages, Outlook 19.8%, Yahoo 16.2%, and Apple Mail 28.1%. Yahoo subscribers also had the lowest click rate at 2.1%, suggesting deliverability or content-fit issues. Apple Mail's higher open rate may reflect Mail Privacy Protection inflating the metric. Consider segmenting Yahoo recipients for a re-engagement campaign or reviewing subject lines for that cohort.
This synthesis example pairs Sequenzy's metrics API with the AI's analytical reasoning to surface actionable insights. Mailbox-provider filtering is powerful but remember that Apple MPP can skew open rates. Requires read access to workspace-level analytics; individual campaign breakdowns need separate queries.
Use-case deep-dives
When Sequenzy wins for debugging drip campaigns at 10-person teams
A 10-person SaaS startup notices trial users aren't converting after the welcome sequence. The support lead needs to trace one subscriber's journey—which emails fired, which bounced, which sequence they're stuck in—without asking engineering to write SQL. Sequenzy's Get Subscriber tool surfaces the full timeline in one call: list memberships, sequence enrollments, engagement totals, recent activity. The team can spot the broken step (usually a tag rule or a paused sequence) in under five minutes. This MCP is the right call if your email vendor is Sequenzy and your team runs fewer than 20 sequences; beyond that threshold, you'll want a BI tool that aggregates across campaigns. If you're debugging individual subscriber paths or auditing tag hygiene before a big launch, connect this MCP and ask your AI to pull the subscriber record.
When workspace-wide metrics replace manual CSV exports
A three-person marketing team at a B2B consultancy reviews email performance every Monday morning. They used to export CSVs from Sequenzy, paste them into Google Sheets, and calculate open rates by hand. Now they ask their shared AI workspace to run Get Email Metrics for the past seven days, filtered by campaign type and mailbox provider. The AI returns delivery totals, engagement rates, and provider-specific bounce patterns in plain English. The team spots Gmail throttling issues or low-performing subject lines without opening the Sequenzy dashboard. This workflow breaks down if you send more than 50 campaigns a week—the API returns workspace totals, not per-campaign breakdowns, so high-volume senders need a dedicated analytics stack. If your team sends 5-15 campaigns a month and wants to skip the export-paste-calculate loop, this MCP saves 20 minutes every standup.
When bulk tag operations prevent subscriber-list chaos
A four-person product team is launching a new feature tier and needs to retire 12 old tags that no longer map to the pricing model. Deleting tags by hand in the Sequenzy UI risks leaving orphaned references in sequences or breaking active automations. The team connects this MCP and asks the AI to list all tags, identify which ones are referenced by active sequences, and delete only the safe candidates. The Delete Tag tool rejects any tag still in use, so the AI reports back which tags need sequence edits first. The team resolves the cleanup in one 30-minute session instead of three days of back-and-forth with support. This approach only works if you have fewer than 100 tags and 20 sequences; larger workspaces need a migration script. If you're consolidating tags before a rebrand or launch, this MCP prevents the accidental cascade deletions that break automations.
Frequently asked
What does the Sequenzy MCP let me do in Switchy?
It gives your AI agents read access to Sequenzy subscribers, campaigns, sequences, and email metrics, plus the ability to create and delete custom tags. You can query subscriber details, check engagement rates, and list automation workflows—but you can't send emails or enroll people in sequences through the MCP.
Do I need admin access to connect Sequenzy?
You need a Sequenzy API key with workspace-level read permissions and tag-management rights. Sequenzy doesn't expose granular OAuth scopes; the key either has access to the workspace or it doesn't. If you can generate an API key in your account settings, you can connect it.
Can the Sequenzy MCP send campaigns or enroll subscribers in sequences?
No. The MCP is read-only for campaigns and sequences—it lists them and shows their status, but it can't trigger sends or add subscribers to automation flows. If you need to send email or manage enrollments, use Sequenzy's dashboard or a separate automation tool.
How is this different from using Sequenzy's API directly?
The MCP wraps ten common read-and-tag operations so your AI can query subscriber data and metrics in natural language, without you writing API calls. It's faster for ad-hoc questions but narrower than the full Sequenzy API—you won't find campaign-creation or webhook-configuration endpoints here.
Who on the team should connect the Sequenzy MCP?
Whoever owns your Sequenzy workspace and can generate API keys. Because the MCP can delete tags workspace-wide, you want someone who understands your tagging taxonomy. Marketing ops or the team lead is usually the right person; junior campaign managers probably shouldn't hold the key.
