Tools
- Archive Tag
Archive one customer-managed tag. Archiving prevents new assignments but preserves existing subscriber assignments and can be reversed by restoring the tag. Use the tag-usage tool first to inspect archive blockers.
- Count Segment Subscribers
Return the current number of subscribers matching one stored segment.
- Create Segment
Create a subscriber segment from field, tag, or nested-segment conditions.
- Create Subscriber
Create a subscriber without sending an opt-in message, with optional typed field values and tag assignments.
- Create Subscribers
Sequentially create 1-25 subscribers without sending opt-in messages. The batch is non-atomic, returns an outcome for every item, and stops after a systemic or ambiguous failure.
- Create Tag
Create a customer-managed tag that can be assigned to subscribers.
- Delete Segmentdestructive
Permanently delete exactly one stored subscriber segment identified by an explicit segment ID. This action cannot select segments by filter or bulk criteria.
- Delete Subscriberdestructive

How Switchy teams use it
Starter prompts
Bulk Import Leads
@Maildroppa create subscribers from this list: [paste names and emails]. Assign the tag 'Q1_Welcome' to all of them and set the 'source' field to 'webinar'.
Segment Size Check
@Maildroppa count segment subscribers for segment ID 'seg_abc123'. I need the current total to size my send window.
Archive Unused Tags
@Maildroppa archive the tag 'Old_Promo_2023'. First show me its current usage stats so I know what's affected.
Create Custom Segment
@Maildroppa create a segment named 'High_Intent_Q2' that includes subscribers with the tag 'Downloaded_Whitepaper' and the field 'industry' set to 'SaaS'.
Delete Subscriber by ID
@Maildroppa delete subscriber ID 'sub_xyz789'. Confirm the email address first so I know we're removing the right record.

@maildroppa count how many subscribers are in our 'trial-expired' segment and list the top 5 tags assigned to them
The 'trial-expired' segment currently contains 1,247 subscribers. The five most common tags assigned to these subscribers are: 'product-interest-analytics' (892 subscribers), 'onboarding-incomplete' (634 subscribers), 'support-ticket-open' (421 subscribers), 'enterprise-inquiry' (287 subscribers), and 'webinar-attended' (203 subscribers). This data reflects the state of your Maildroppa account as of this query.
This example combines segment counting with tag analysis to surface actionable patterns. The MCP reads existing segment and tag data but does not create campaigns or send mail. You'll need API credentials with read access to segments and tags. Counts reflect real-time state and may shift between queries.
@maildroppa create a new segment called 'high-value-dormant' for subscribers who have the 'purchased' tag but haven't opened an email in 90 days
Created segment 'high-value-dormant' (ID: seg_k3m9x) with conditions: tag equals 'purchased' AND last-opened-at is older than 90 days. The segment currently matches 412 subscribers. You can now reference this segment in campaigns or use it to trigger re-engagement workflows. The segment updates dynamically as subscriber behavior changes.
This example demonstrates segment creation from behavioral and tag-based conditions. The MCP writes a new segment definition to your Maildroppa account. Segment logic evaluates continuously, so the subscriber count will drift over time. Requires API write permissions for segments.
@maildroppa create 3 test subscribers with emails test1@example.com through test3@example.com, assign them the 'qa-sandbox' tag, and confirm they won't receive opt-in emails
Created 3 subscribers without opt-in messages: test1@example.com (ID: sub_a1b2c), test2@example.com (ID: sub_d3e4f), test3@example.com (ID: sub_g5h6i). All three have been assigned the 'qa-sandbox' tag. These subscribers are immediately active in your account and will appear in segment counts and campaign audiences. No confirmation emails were sent per the no-opt-in flag.
This example shows batch subscriber creation with tag assignment, useful for testing or importing pre-verified contacts. The MCP writes directly to your subscriber list—there's no undo short of manual deletion. The no-opt-in flag bypasses double opt-in workflows, so ensure you have consent. Batch limit is 25 subscribers per call.
Use-case deep-dives
When Maildroppa beats Mailchimp for product-led teams
A 6-person SaaS startup runs a 14-day onboarding sequence triggered by trial signups. The product engineer owns the flow and needs to tag users by feature adoption milestones without leaving the codebase. Maildroppa's 23-tool MCP wins here because Create Subscriber and Create Tag let you script the entire lifecycle from a shared AI workspace—no context-switching to a marketing UI. The segment-builder tools (Create Segment, Count Segment Subscribers) let your PM validate cohort sizes before launching campaigns. This breaks down if you need visual journey builders or A/B testing dashboards; Maildroppa is API-first, so non-technical stakeholders will still need vendor login for campaign design. If your onboarding logic lives in code and your team prefers programmatic control over drag-and-drop, route signup webhooks through Switchy and let the MCP handle tagging and list hygiene.
Tagging support contacts for targeted campaigns
A 12-person B2B support team closes 200 tickets a week in Zendesk and wants to loop solved-issue contacts into a monthly feature-update newsletter. The support lead uses Switchy to query closed tickets, then calls Maildroppa's Create Subscribers batch tool to add up to 25 emails at once with a 'resolved-this-month' tag. The Archive Tag tool keeps old campaign tags from cluttering the workspace without losing historical assignments. This workflow stays fast until you hit ~500 subscribers per sync—beyond that, the 25-item batch limit means you're chaining multiple calls and the MCP's lack of bulk-delete makes cleanup tedious. If your support volume is under 1,000 contacts a month and you want one-click sync from ticket data to email segments, Maildroppa's MCP removes the CSV export step and keeps your CRM and email list in lockstep.
When segment-building replaces spreadsheet hell
A 4-person conference team registers 800 attendees across early-bird, speaker, and sponsor tiers. The ops manager needs to send tier-specific pre-event emails without manually filtering a Google Sheet every time. Maildroppa's Create Segment tool builds dynamic lists from tag conditions (early-bird AND not-checked-in), and Count Segment Subscribers confirms list size before hitting send. The Delete Segment and Delete Subscriber tools let you prune test records and duplicate signups without vendor-UI lag. This falls apart if you need real-time webhook triggers or sub-second segment updates—Maildroppa's API is request-based, not event-driven. If your event cadence is quarterly or slower and your team already tracks registration state in tags, the MCP turns ad-hoc list pulls into repeatable Switchy prompts and cuts pre-send prep from 20 minutes to 2.
Frequently asked
What does the Maildroppa MCP do in Switchy?
It connects your Maildroppa email marketing account so AI agents can create subscribers, manage tags and segments, and query list data without leaving the conversation. You can ask an agent to add leads from a spreadsheet, build audience segments from conditions, or check how many people match a filter—all through natural language instead of clicking through the Maildroppa dashboard.
Do I need admin access to connect Maildroppa?
You need a Maildroppa API key, which typically requires account owner or admin permissions to generate. The key grants full read-write access to subscribers, tags, and segments, so only connect accounts where your team is authorised to modify list data. If you're on a shared Maildroppa workspace, confirm with the account owner before connecting.
Can the MCP send email campaigns or trigger automations?
No. The MCP handles subscriber management—creating contacts, assigning tags, building segments, counting audiences—but it doesn't send campaigns or trigger automation sequences. If you need to launch a broadcast or start a drip series, you'll still use Maildroppa's web interface or their separate campaign API endpoints.
How is this different from uploading a CSV to Maildroppa directly?
The MCP lets AI agents create subscribers on the fly during a conversation, validate data against your custom fields, and immediately segment new contacts based on logic you describe in plain English. A CSV upload is faster for bulk imports you've already cleaned, but the MCP shines when you're iterating on list-building workflows or need to add contacts conditionally as part of a larger agent task.
Who on the team should connect the Maildroppa integration?
Whoever owns your email list strategy and has permission to create or delete subscribers. Marketing ops or growth leads are typical owners. Avoid connecting it to personal API keys that might be revoked when someone leaves, and remember that any teammate with Switchy workspace access can invoke the MCP's tools once it's connected.
