Setup
Setup guide
- 11. Open your Switchy workspace settings and navigate to the Integrations tab. 2. Search for DirectIQ and click Connect. 3. You'll be prompted to paste your DirectIQ API key, which you generate inside your DirectIQ account under API Settings or Developer Tools. 4. Grant the key permission to send transactional emails (DirectIQ typically calls this 'send' scope). 5. Click Save to complete the connection. 6. Open any Project and type '@DirectIQ send an email to test@example.com with subject Test from Switchy' to verify the integration works. 7. Check the recipient inbox and your DirectIQ dashboard to confirm delivery. 8. From now on, @mention DirectIQ in any Project thread to send transactional emails on demand — the MCP will use your verified sender address and route through DirectIQ's infrastructure.
What teammates see: by default, memories from DirectIQ are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@DirectIQ draft and send a weekly digest email to team@company.com summarizing the last 7 days of project activity from our task tracker
This prompt combines AI synthesis with DirectIQ's send capability. The assistant would first retrieve recent project activity (if another MCP provides task-tracker access), generate a plain-text or HTML digest, then invoke DirectIQ to deliver it to team@company.com. DirectIQ confirms the send with a message ID. The resulting email reflects the AI's summary style and the data available at prompt time—content will vary week to week.
Showcases cross-MCP orchestration: the AI reasons over external data, composes prose, and hands off delivery to DirectIQ. This workflow requires both a data source (another MCP or manual context) and a DirectIQ API key with send permissions. Because sends are immediate and non-idempotent, consider scheduling such prompts carefully to avoid duplicate digests if a teammate re-runs the same request.
Use-case deep-dives
When DirectIQ works for single-email transactional flows
A 3-person e-commerce team needs order confirmations sent the moment a Stripe webhook fires. DirectIQ's single-tool MCP is the right call here: one recipient, one immediate send, no batching logic to manage. The API key auth means your AI can trigger sends without OAuth friction, and the non-idempotent warning matters—if your webhook retries, you'll send duplicates, so wrap the call in your own deduplication layer. This MCP isn't built for bulk campaigns or multi-recipient workflows; it's a narrow tool for transactional one-offs. If you're sending password resets, signup verifications, or payment receipts and you already use DirectIQ for marketing, this keeps your stack consolidated. For teams sending under 500 transactional emails a day with simple triggering logic, it's a clean fit.
DirectIQ for customer service email triggers at small scale
A 5-person support team wants to notify customers when a Zendesk ticket moves to 'resolved' or 'waiting on customer.' DirectIQ's MCP can fire those updates from your AI workflow without building a separate email service. The single-tool scope means you're calling one function per send—fine when ticket volume is under 100 updates a day, but the lack of batching or queuing makes this a poor choice if you're triaging 500+ tickets daily. The non-idempotent behavior is a trap: if your AI retries a failed send, the customer gets duplicate 'your ticket is resolved' emails, which erodes trust. You'll need retry logic with a send-tracking table on your side. If your support load is predictable and low-frequency, and you want transactional sends inside an AI-driven triage flow, DirectIQ works. Above 200 sends a day, look for a batching-capable MCP.
When DirectIQ fits single-attendee event notifications
A 6-person event ops team runs monthly webinars with 40-80 registrants and wants AI-generated reminder emails sent 24 hours before each session. DirectIQ's MCP handles this if you're okay with sequential sends—one API call per attendee, no bulk endpoint. At 80 sends per event, that's manageable; at 500+ registrants, the lack of batching becomes a bottleneck and you'll hit rate limits or slow execution. The API key auth is simple, but the non-idempotent design means if your scheduler misfires and retries, some attendees get double reminders. You need external deduplication or a sent-log before calling the MCP. If your events are small, infrequent, and you want transactional sends wired into an AI calendar workflow, DirectIQ works. For larger cohorts or daily event cadences, choose an MCP with batch-send tools.
Frequently asked
What does the DirectIQ MCP do in Switchy?
It sends transactional emails from your DirectIQ account — order confirmations, password resets, alerts. The MCP exposes one tool that fires a single email to one recipient immediately. It's designed for programmatic sends triggered by AI workflows, not bulk campaigns or marketing sequences.
Do I need a DirectIQ admin account to connect this MCP?
You need an API key from DirectIQ, which typically requires account-owner or admin permissions to generate. The key authenticates all send requests, so whoever connects it in Switchy controls which sender addresses and templates the team can use. Check your DirectIQ dashboard under API settings.
Can the DirectIQ MCP send bulk emails or newsletters?
No. It sends one email at a time to one recipient. If you call the tool twice with the same content, DirectIQ will send two separate emails — there's no deduplication. For bulk sends or marketing campaigns, use DirectIQ's web interface or their dedicated campaign API instead.
How is this different from using DirectIQ's dashboard or API directly?
The MCP lets AI agents send transactional email without you writing integration code. You describe the send in natural language; the agent calls the tool. The trade-off: you lose fine-grained control over retry logic, batch sends, and delivery webhooks that DirectIQ's full API provides.
Who on the team should connect the DirectIQ MCP?
Whoever owns your transactional email infrastructure — usually a developer or ops lead. They'll need the API key and should understand which sender addresses are verified in DirectIQ. Once connected, any Switchy user with workspace access can trigger sends through AI workflows.
