Reteno

@Reteno list all contacts whose email domain is @acme.com and show me their subscription status

Found 47 contacts with @acme.com email addresses in your Reteno workspace. The list includes contact IDs, names, email addresses, phone numbers, and current subscription status (subscribed, unsubscribed, or bounced). Of these, 39 are actively subscribed to marketing emails, 6 have unsubscribed, and 2 are marked as bounced. Each contact record also shows the date they were added to Reteno and their last activity timestamp. Note that this is a paginated result; if you have more than 100 matching contacts, you'll need to request subsequent pages.

This example uses List Contacts with email filtering. Reteno's API returns paginated results (typically 100 records per page), so large contact lists require multiple calls. The MCP needs a valid API key with read access to contacts. Filtering by domain requires partial-match support; check the MCP's implementation to confirm substring search works as expected.

@Reteno create a new contact for jane.doe@example.com with phone +1-555-0199, then add her to the 'Product Updates' address book

Contact created successfully. Reteno assigned internal contact ID `ret_c_8x7k2m` to jane.doe@example.com. The contact record now includes the phone number +1-555-0199 and default subscription status (subscribed). I've added this contact to the 'Product Updates' address book (book ID `ab_9f3j1`). The import operation is processing asynchronously; Reteno typically completes address book assignments within 30 seconds. You can check the import status with Get Contact Import Status if you need confirmation before sending a campaign.

This example chains Upsert Contacts with address book assignment. Reteno processes contact imports asynchronously, so the contact may not appear in campaigns immediately. The MCP requires API key permissions for both contact creation and address book management. Be aware that creating duplicate contacts (same email or phone) will update the existing record rather than create a new one.

@Reteno pull the last 30 days of email message history for contact ID ret_c_8x7k2m and summarize which campaigns had the highest open rates

Contact ret_c_8x7k2m received 12 email messages in the past 30 days. The message history shows campaign names, send timestamps, delivery status, open events, and click events. Three campaigns stand out: 'Weekly Digest #47' had a 68% open rate with 4 link clicks, 'Flash Sale Alert' achieved 55% open rate with 2 clicks, and 'Product Launch Announcement' reached 51% open rate with 6 clicks. The remaining 9 messages averaged 22% open rate. Two messages bounced due to a temporary mailbox-full error on days 12 and 13, but subsequent sends delivered successfully.

This example combines List Contact Messages with AI summarization to surface engagement patterns. Reteno's message history API requires a date range (maximum 90 days) and returns one channel at a time (email, SMS, push, etc.). The MCP must have read access to message logs. Open and click tracking depends on the contact's email client settings; some privacy features block tracking pixels.

When support needs full message history in one call

A six-person support team handling 200 tickets a day needs to see what emails and SMS a customer received before they opened the ticket. Reteno's List Contact Messages tool pulls the full timeline for a date range without switching tabs or logging into a separate dashboard. The Get Contact tool adds profile fields like subscription tier or last purchase date. This works when your support volume is low enough that agents can afford the extra 2-3 seconds to fetch history on demand. If you're triaging 50 concurrent chats, pre-caching message history in your helpdesk is faster. For teams under 10 agents who want context without a custom integration, Reteno's MCP gives you the lookup speed you need.

Why this MCP matters for pre-send list checks

A three-person marketing team at a SaaS company is about to send a product launch email to 12,000 contacts. Before hitting send, they want to confirm the address book actually excludes churned accounts and includes the new trial signups from last week. The List Address Books and List Contacts tools let them spot-check segment membership and field values in Switchy without exporting CSVs or opening the Reteno UI. The Get Contact Import Status tool confirms the morning's trial upload finished. This scenario breaks down if your contact list exceeds 50,000 rows—pagination makes manual verification slow. For small teams sending fewer than five campaigns a week, Reteno's MCP turns pre-flight checks into a 90-second Switchy conversation instead of a 10-minute UI drill.

When finance needs real-time spend visibility

A startup's finance lead wants to track Reteno spend weekly without waiting for the monthly invoice. The Get Account Balance tool returns prepaid SMS and email quotas, credit limits, and current balance in one call. The Get Account Info tool confirms which API user and organization the balance belongs to, which matters when you're managing multiple brands or subsidiaries. This is useful when your messaging volume is unpredictable—Black Friday spikes or a viral product launch can burn through prepaid credits fast. If your monthly spend is under $500 and stable, checking balance once a quarter in the Reteno dashboard is enough. For teams scaling fast or running tight budgets, Reteno's MCP gives you the weekly pulse check you need to avoid surprise overages.
