Managing direct mail is currently a nightmare of spreadsheets and half-used labels.
Today, running a simple campaign means exporting a list to Excel. You manually cross-reference names with address databases, check if the recipient is in the right segment, then either pay for a dedicated mailing service API or spend hours updating individual records in your CRM just to send one card.
With MailboxPower, you stop clicking and start talking. Your agent handles the entire data flow. You simply tell it who needs what, and it executes `send_shipment` using accurate contact details retrieved via `get_contact`. The whole process runs from a single chat window.
MailboxPower MCP Server: Send physical items with the `send_shipment` tool
Before, sending even three personalized gifts required multiple logins: one for CRM data, one for inventory lookup, and a third for shipping confirmation. Errors were guaranteed.
Now, you specify the gift, the recipient, and the message to your agent. The agent runs `send_shipment` and completes the transaction—calculating costs, confirming delivery estimates, and logging it all back into your workflow. It’s that simple.
What your AI can actually do with this
You connect MailboxPower straight into your AI agent. You handle physical direct mail marketing—like sending thank-you cards or promotional gifts—right from your chat interface. This server lets you run entire campaigns without ever leaving your conversation.
Managing Your Contacts:
When you need to know who you're talking to, you can use list_contacts to pull a full list of every contact the system manages. Got details on one person? You invoke get_contact to retrieve all known info, like their address and name. If you find someone new, just run create_contact to build a brand-new record with all the necessary details.
Organizing Mailing Lists:
Targeting is key when you're sending physical items. You can use create_group to define and set up an entirely new mailing group for your campaign. Once that group exists, you add existing contacts using add_contact_to_group, putting them right where they need to be for the send. To check what groups you've built or which people are in 'em, run list_groups.
Executing Campaigns:
Sending physical items is simple. You call send_shipment and tell it exactly what to mail—a card, a gift, or some merch—and where to send it. The system handles the rest of the mailing process for that specific address.
Building Automated Workflows:
MailboxPower doesn't just send stuff; it automates your outreach. You can use add_contact_to_automation to trigger a complex workflow sequence for a specific person as soon as they meet certain criteria. To see what kind of automated sequences you've got running, or what triggers are active, you run list_automations.
This helps you track the status and flow of your ongoing mail campaigns across every recipient.

Here's how it actually works
The bottom line is you talk naturally to your AI client, and it handles the entire physical mailing process using MailboxPower's tools.
First, subscribe to the server and enter your MailboxPower API Key into your AI client.
Next, tell your agent exactly what you want. For example: 'Send a gift box to John Doe' or 'Create a group for all Q2 clients.'
The agent uses the underlying tools (like send_shipment or create_group) to run the action and returns confirmation details, like delivery estimates and costs.
Who is this actually for?
This is for Sales Operations professionals who hate having to switch between their CRM and a separate email marketing platform just to send a thank-you gift. It’s also built for Marketing Managers who need to run complex, physical campaigns (like client appreciation) but don't want the technical overhead of manual API calls.
Sending personalized gifts or cards to prospects after a pitch. They tell their agent: 'Send a premium basket gift to Jane Smith.'
Building and managing complex mailing campaigns, like creating an entire group of 'Top Tier Clients' before scheduling the bulk send using create_group.
Handling retention efforts by sending thank-you cards or branded items to clients who haven't logged in recently.
What Changes When You Connect
Send items instantly. Use send_shipment to send a gift box or thank-you card. You just describe the item and recipient, and it handles the fulfillment details.
Stay organized with groups. Instead of mailing one by one, use create_group and list_groups to define entire segments (e.g., 'Q2 Platinum Clients') for bulk sending.
Verify addresses fast. Before launching a campaign, run get_contact to check if the recipient's address is current. This prevents failed deliveries.
Build repeatable workflows. Use add_contact_to_automation when you want an action (like a 3-month follow-up gift) to happen automatically after a key milestone.
Know your audience. Run list_contacts or list_groups any time you need a master list of who's in the system before building a campaign.
See it in action
The 'Thank You' follow-up after a pitch
A sales rep needs to send a personalized thank-you card and small gift box immediately. They tell their agent: 'Send a Thank You card and a coffee mug gift to Alex Jones.' The agent uses send_shipment, pulling the address from the contact record, ensuring the physical item goes out right away.
Launching an annual client appreciation campaign
Marketing needs to target 50 top clients. Instead of manually listing them, they run list_contacts and then use the agent to build a group: 'Add all contacts from the spreadsheet into the Platinum Group.' They then schedule the bulk mailing via send_shipment.
Handling new leads that need nurturing
A lead comes in and needs immediate follow-up. The agent first runs create_contact with the new details, then uses add_contact_to_automation to put them into a 90-day nurture flow so gifts start sending automatically.
Checking delivery status for large campaigns
The team runs a multi-state campaign. To check the progress, they ask the agent to 'Show me the active shipments.' The system uses internal tracking data and provides an immediate report on which items are delivered or in transit.
The honest tradeoffs
Manual address entry
A team member manually types out a client's address into a spreadsheet for mailing, only to realize the ZIP code is wrong and the campaign fails.
Always use get_contact first. This pulls verified details directly from the CRM record, ensuring accuracy before running send_shipment. The agent handles the validation.
Sending items to the wrong segment
A manager wants to send a gift only to 'Executive Tier' clients but accidentally sends it to everyone in the main contact list.
Never rely on individual contacts. Use create_group or add_contact_to_group first to isolate the exact segment, then run send_shipment only against that specific group.
Forgetting follow-up triggers
The team sends a gift, but nothing happens until 6 months later. They miss the window for timely follow-ups.
Use add_contact_to_automation immediately after sending the item. This locks in a future date and ensures your agent handles the next touchpoint without manual reminders.
When It Fits, When It Doesn't
Use this server if physical, tactile follow-up is central to your sales or marketing process. If your goal requires a physical gift, card, or piece of swag, this is what you need. Don't use it if all you need is digital communication (like sending an email or updating a record). For pure data management tasks—like simply listing contacts without the intent to mail anything—the basic CRM tools might suffice. But once you involve shipping, send_shipment makes this necessary. If your process involves complex, multi-step nurturing over months, rely on the combination of create_group, and add_contact_to_automation. Never try to manage physical inventory or mailing lists without first checking the status using list_groups.
Questions you might have
How do I start a gift campaign using send_shipment? +
You specify the product and the recipient's details in one prompt. The agent uses send_shipment to execute the order, providing cost estimates and estimated delivery dates immediately.
Can I group contacts before sending mail with MailboxPower? +
Absolutely. Use list_contacts first to see everyone, then use create_group or add_contact_to_group to build your target list. You run the shipment against that group.
What if I need to update an address before sending a card? Should I use get_contact? +
Yes, always use get_contact. This pulls the most current, verified data for that person. It ensures send_shipment doesn't fail because of outdated information.
Is there a way to automate follow-up gifts? +
Yes. After sending an item, use add_contact_to_automation. This sets up the next touchpoint—like a gift 90 days later—so you don't have to remember it.
Does MailboxPower handle product catalog browsing? +
Yes, you can browse the available inventory (products, cards, promo items) directly through the conversation. This lets you figure out what gifts fit a budget before running send_shipment.
What credentials do I need to use the `list_groups` tool? +
You must provide a valid MailboxPower API key in your server configuration. The agent uses this key to authenticate your connection and confirm you have the necessary permissions to view group data.
When using the `send_shipment` tool, how does it handle contacts with incomplete or invalid addresses? +
The tool validates recipient details before attempting shipment. If an address fails validation (e.g., missing zip code), it flags the record and skips sending that specific item, returning a detailed error log.
Is there a limit when running the `list_contacts` tool on a large dataset of records? +
The tool supports pagination. When querying more than 100 contacts, your agent must iterate through subsequent pages using the provided cursor token to pull all available data.
Can I send personalized gifts and cards? +
Yes. Browse the product catalog, personalize gifts and cards with custom messages, and send to any US address with delivery tracking.
Can I run direct mail campaigns? +
Yes. Create campaigns with recipient lists, schedule mailings, and track delivery status for each piece.
What API does MailboxPower use? +
Bearer authentication against api.mailboxpower.com/v1.
