Setup
Setup guide
- 11. In Switchy, open your workspace settings and navigate to the Integrations tab. 2. Search for Stannp and click Connect. 3. You'll be prompted to paste your Stannp API key, which you generate by logging into your Stannp account, going to Settings > API, and clicking Create New Key. 4. Copy the key and paste it into Switchy, then click Authorize. 5. Once connected, open any Space and type '@Stannp list templates' to confirm the integration works — you should see your account's available templates. 6. To invoke a tool during a conversation, @mention Stannp followed by your request, like '@Stannp create a recipient group called Q1 Launch' or '@Stannp import recipients from this CSV into the Launch group'. The AI will parse your intent and call the appropriate tool.
What teammates see: by default, memories from Stannp are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

@stannp list all my direct mail templates and show me which ones have been used in the last 30 days
Based on your Stannp account, you have 8 templates available. Here's a summary: 'Holiday Promo 2024' (postcard, last used 12 days ago), 'Product Launch Announcement' (letter, last used 3 days ago), 'Customer Thank You' (postcard, unused in 30 days), 'Spring Sale Flyer' (A5 flyer, last used 18 days ago), and 4 others that haven't been used recently. The Product Launch template appears to be your most active campaign format this month.
This example shows Stannp's template retrieval capability. The MCP returns template metadata; usage tracking may require cross-referencing with campaign data. Requires valid API key with read access to templates. Response time depends on account size but is typically under 2 seconds.
@stannp create a new recipient group called 'Q1 2024 Prospects' and add the contact with ID 847392 to it
I've created the recipient group 'Q1 2024 Prospects' in your Stannp account (Group ID: RG-5829). Contact 847392 (Sarah Chen, sarah.chen@example.com) has been successfully added to this group. The group is now ready for campaign targeting. You can add more recipients individually or import a bulk list whenever you're ready to expand this segment.
This demonstrates Stannp's contact organization workflow—creating groups and adding members. Both operations modify your account state. The MCP performs these as separate API calls in sequence. If the contact ID doesn't exist, the add operation will fail after the group is created, leaving an empty group.
@stannp pull all contacts from my 'VIP Customers' group and draft a personalized postcard message thanking our top 5 spenders this quarter
I retrieved 47 contacts from your 'VIP Customers' group. Based on the contact data fields available, your top 5 by lifetime value appear to be: James Wilson ($12,400), Maria Garcia ($11,850), Robert Taylor ($10,920), Linda Chen ($9,780), and David Park ($9,340). Here's a draft postcard message: 'Dear [First Name], Your loyalty means everything to us. As one of our most valued customers this quarter, we wanted to say thank you with an exclusive 20% discount on your next order. Use code VIP20Q1 by March 31st. With gratitude, [Your Company]'
This example combines Stannp's contact retrieval with AI reasoning to analyze and personalize messaging. The MCP provides raw contact data; the AI interprets spending patterns if that field exists in your Stannp records. Actual field availability varies by account setup—you may need to enrich contact data separately.
Use-case deep-dives
When Stannp wins for physical event invitations at scale
A 6-person nonprofit running a donor gala needs to send 400 printed invitations with personalized salutations and table assignments. Stannp's recipient groups and CSV import tools let the team upload their donor list once, map custom fields to template variables, and trigger the print job without touching Canva or a print vendor's portal. The MCP shines when your event list is already in a spreadsheet and you need merge fields beyond name and address—think donation tier, plus-one status, or assigned table number. If you're sending under 50 invites or your design changes per recipient, the setup overhead outweighs the benefit. For recurring events with stable templates and lists over 200, Stannp cuts the manual work by half.
When this MCP fits quarterly customer appreciation sends
A 12-person SaaS company wants to mail thank-you postcards to their top 80 customers each quarter, pulling names and addresses from their CRM export. Stannp's import tool accepts the CSV directly, and the team can reuse the same postcard template across quarters by swapping the recipient group. The MCP works when your mailing list is stable enough to batch but small enough that you're not automating via Zapier or a full marketing platform. If you're sending to the same 80 people every time, just update the group and re-trigger. If your list changes by more than 30% each send or you need A/B testing, you'll hit the limits of Stannp's recipient management and want a dedicated direct mail platform instead.
When Stannp handles neighborhood-targeted property postcards
A 3-person real estate team runs open houses twice a month and mails postcards to 300-500 homes within a half-mile radius of each listing. They export the address list from their MLS tool, import it into a new Stannp recipient group per property, and send using a template with the listing photo and open house date. The MCP is the right call when you're doing repeat sends to different geographic segments and your design is consistent across listings—Stannp's template system keeps the workflow fast. If you're mailing to the same neighborhood every time, the recipient group overhead is overkill; just use a static list. If you need tracking beyond delivery confirmation or want to coordinate digital retargeting, Stannp's tooling stops short and you'll want a platform with attribution hooks.
Frequently asked
What does the Stannp MCP do in Switchy?
It lets AI agents manage your direct mail campaigns by creating recipient groups, importing contact lists from CSV files, and retrieving template details. Your team can automate mailing list operations without logging into Stannp's dashboard. The MCP handles contact organization and list imports, not actual mail sending or design work.
Do I need admin access to connect Stannp?
You need a Stannp API key, which typically requires account owner or admin permissions to generate. The key grants full access to your recipient groups and templates, so treat it like a password. If you're not the account owner, ask them to create a dedicated API key for Switchy rather than sharing their personal credentials.
Can the Stannp MCP send physical mail or create designs?
No. It manages recipient lists and retrieves template information, but it doesn't trigger mail sends or edit designs. You'll still use Stannp's web interface or their separate sending API for campaign execution. Think of this MCP as your contact database manager, not your mail room.
Why use this instead of uploading CSVs directly in Stannp?
It's faster when you're already working with data in Switchy. If an AI agent pulls a customer list from your CRM, it can push that straight into a Stannp recipient group without you downloading a CSV, logging into Stannp, and clicking through their import wizard. Saves three manual steps per list update.
Who on my team should connect the Stannp integration?
Whoever manages your direct mail campaigns and has access to your Stannp API key. Usually that's your marketing ops person or whoever owns your mailing list hygiene. They'll need to paste the API key into Switchy once; after that, any team member with Switchy access can use the integration in their AI workflows.
