Setup guide

You'll be prompted to enter your Sendloop API key — find this in your Sendloop account under Settings > API Access. 4. Copy the key and paste it into Switchy, then click Authorize. 5. Switchy confirms the connection by fetching your account information in the background. 6. Open any Space and type '@Sendloop what campaigns did we send this month?' to test. 7. If the MCP returns a list of campaigns, you're connected. 8. If you see an authentication error, double-check the API key hasn't expired and that your Sendloop plan includes API access.

Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@sendloop show me all my subscriber lists and how many active subscribers are in each one
Here's what I found in your Sendloop account: • **Newsletter Subscribers** – 2,847 active subscribers • **Product Updates** – 1,203 active subscribers • **Weekly Digest** – 894 active subscribers • **Beta Testers** – 156 active subscribers This is an illustrative example. Your actual list names, counts, and structure will vary based on your Sendloop account configuration.
This example demonstrates the read capability for retrieving all mailing lists. Requires a valid API key with list-read permissions. The MCP returns list metadata including subscriber counts, which helps teams understand their audience segmentation at a glance without logging into the Sendloop dashboard.
@sendloop pull the campaign performance report for our last newsletter send — I need open rates and click rates
Here's the performance summary for your most recent campaign: **Campaign:** Weekly Newsletter #47 **Sent:** 2,847 recipients **Opens:** 891 (31.3%) **Clicks:** 203 (7.1%) **Bounces:** 12 (0.4%) **Unsubscribes:** 3 (0.1%) This is an illustrative example showing typical email metrics. Actual report data depends on your campaign history and requires the campaign to have been sent.
This showcases the reporting tool that retrieves post-send analytics. Use this after campaigns have been delivered to assess engagement. The MCP fetches summary metrics but not granular click-maps or individual recipient behavior. Useful for quick performance checks during team standups or retrospectives.
@sendloop compare our last three campaign open rates and tell me if we're trending up or down
I retrieved your last three campaigns and here's the trend: 1. **Weekly Newsletter #47** – 31.3% open rate 2. **Weekly Newsletter #46** – 28.7% open rate 3. **Weekly Newsletter #45** – 26.9% open rate **Analysis:** Your open rates are trending upward over the last three sends, improving by roughly 4.4 percentage points. This suggests your subject lines or send timing may be resonating better with your audience recently. This is an illustrative example combining list and report data with AI reasoning.
This example pairs the MCP's campaign listing and reporting tools with the AI's ability to synthesize trends. The MCP provides raw metrics; the AI interprets direction and context. Requires API access to campaign history. Helpful for spotting performance shifts without manual spreadsheet work.
Use-case deep-dives
When Sendloop MCP speeds up weekly campaign retrospectives
A 3-person marketing team at a SaaS startup sends two email campaigns per week and reviews performance every Friday. The Sendloop MCP is the right call here because it pulls list reports and campaign metrics directly into Switchy, letting the team compare open rates and subscriber growth without switching tabs. The AI can answer "which campaign had better engagement this week" or "how many new subscribers joined after the webinar promo" in seconds. The threshold: if your team runs A/B tests across dozens of variants or needs granular click-map data, you'll still need Sendloop's dashboard for the visual breakdowns. For straightforward metric checks and list health monitoring, this MCP eliminates the context-switching tax and keeps your retrospective under 15 minutes.
Using Sendloop MCP to audit subscriber status at scale
A 2-person support team at an e-commerce brand maintains four segmented lists (VIP customers, cart abandoners, newsletter subscribers, and unengaged). Once a month, they audit list health to catch bounces and unsubscribes before the next promo. The Sendloop MCP handles this well because it can list subscribers by status and paginate through large lists without manual CSV exports. The AI can answer "how many unsubscribes did we get on the VIP list this month" or "show me bounced emails from the cart-abandoner segment" in one query. The trade-off: if you need to cross-reference subscriber data with Shopify order history or Stripe payment status, you'll need a second MCP or manual reconciliation. For pure list hygiene and status checks, this MCP saves 30 minutes of spreadsheet wrangling per audit.
When Sendloop MCP works for solo email strategists
A freelance email marketing consultant manages campaigns for three clients, each with 2-4 active lists. Before planning a new campaign, she checks account limits, reviews recent campaign performance, and confirms list sizes to avoid send-cap surprises. The Sendloop MCP is a clean fit because it surfaces account info and list counts in Switchy without logging into three separate Sendloop accounts. The AI can answer "what's my remaining send quota for Client A" or "which lists have grown since last month" while she's drafting the campaign brief. The limitation: if she needs to clone a campaign template or edit segment rules, those actions still require the Sendloop UI. For pre-flight checks and quick metric pulls across multiple accounts, this MCP cuts 10 minutes off every campaign kickoff.
Frequently asked
What does the Sendloop MCP do in Switchy?
It connects your Sendloop email marketing account so AI can read campaign performance, list subscribers, and pull account details. You can ask questions like 'how many people opened last week's campaign' or 'show me unsubscribed contacts from the product list' without logging into Sendloop's dashboard. It doesn't send emails or create campaigns — just reads data.
Do I need admin access to connect Sendloop?
You need an API key from your Sendloop account, which typically requires admin or account-owner permissions to generate. The key gives read access to campaigns, lists, and subscriber data. If you're not the account owner, ask whoever manages your Sendloop billing to create the key and share it with you.
Can the Sendloop MCP send emails or edit campaigns?
No. It only reads data — campaign stats, subscriber lists, account info. If you need to send a campaign or update a list, you still log into Sendloop directly or use their API separately. This MCP is for reporting and analysis, not execution.
Why use this instead of Sendloop's dashboard?
The dashboard requires manual clicks and exports to compare campaigns or cross-reference subscriber data. With the MCP in Switchy, you ask natural-language questions and get answers instantly — 'which list has the highest unsubscribe rate this month' or 'pull all bounced emails from the trial list'. Faster for ad-hoc analysis across multiple campaigns.
Who on the team should connect Sendloop to Switchy?
Whoever runs your email campaigns or needs to report on them. Usually a marketing lead or growth person. Since the MCP only reads data, there's no risk of accidental sends. Just make sure they have API key access from your Sendloop account owner.
