Setup
Setup guide
- 11. Log into your Emailable account and navigate to the API section to generate a new API key. 2. In Switchy, open your workspace settings and click 'Connect MCP'. 3. Select Emailable from the list and paste your API key when prompted. 4. Click 'Test Connection' to confirm Switchy can reach Emailable's API and retrieve your account info. 5. Once connected, open any Space and type '@Emailable verify the email address test@example.com' to run your first check. 6. For batch jobs, upload a CSV or paste a list of emails and ask '@Emailable verify this batch' — you'll receive a job ID to track progress. 7. Check your remaining credits anytime by asking '@Emailable show my account info' to avoid mid-batch failures.
What teammates see: by default, memories from Emailable are scoped to the Space (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.

Example outputs
Illustrative - representative of the model's voice and quality, not literal recordings.
@Emailable verify the email address contact@newpartner.io and tell me if it's safe to send our onboarding sequence
Emailable verified contact@newpartner.io with a 'deliverable' status. The address passed SMTP checks, has a valid MX record, and shows no disposable or role-based flags. Risk score is low (0.12). The domain has been active for 3+ years. This address should reliably receive your onboarding emails.
This example shows single-email verification with risk scoring. Each verification consumes one credit from your account balance. The MX and SMTP checks happen in real-time, so expect 2-4 second response times. Useful before adding high-value contacts to campaigns.
@Emailable I have a CSV with 1,200 leads from last week's webinar. Start a batch verification and let me know when it's done
Batch verification initiated for 1,200 email addresses. Job ID: batch_a7k9m2. Emailable is processing these in parallel and will return deliverability status, risk flags, and suggested actions for each address. Current status: 'processing' (estimated completion in 8-12 minutes). I'll check back shortly and summarize the results once complete.
Batch verification handles up to 50,000 emails per job and runs asynchronously. You'll need to poll for status or wait for completion. This example demonstrates the two-step workflow: submit the batch, then retrieve results. Costs one credit per email verified, regardless of outcome.
@Emailable check my account credits and tell me if I have enough capacity to verify our entire CRM export of 8,000 contacts
Your Emailable account (owner: team@company.com) currently has 12,450 verification credits available. Verifying 8,000 contacts would consume 8,000 credits, leaving you with 4,450 remaining. You have sufficient capacity for this job. The batch verification can process all 8,000 in a single request.
Account info retrieval is a read-only operation that doesn't consume credits. Use this before large batch jobs to avoid mid-verification failures. The tool returns current balance but not billing cycle details—plan buffer capacity if you're near renewal dates or have ongoing campaigns.
Use-case deep-dives
When to verify emails before cold outreach campaigns
A 6-person sales team exports 200 leads weekly from their CRM for cold email sequences. Before loading them into their outbound tool, they run the batch through Emailable's Verify Batch Emails tool to flag bounces and catch-alls. This cuts their bounce rate from 8% to under 2%, which keeps their domain reputation clean and their sequences out of spam folders. The trade-off: batch verification costs credits per email, so teams sending under 50 emails a week should use the single Verify Email tool instead to avoid overpaying. If your outreach volume justifies the batch spend and you care about deliverability metrics, Emailable belongs in your pre-send workflow.
Cleaning webinar signups before reminder sequences
A 3-person marketing team runs monthly webinars and collects 400-600 registrations per event. Before scheduling reminder emails, they verify the list with Emailable to remove typos, disposable addresses, and role accounts that won't convert. The Get Batch Status tool lets them check progress without blocking other work, and the detailed risk scores help them segment: high-risk emails get dropped, medium-risk get a single reminder instead of three. The threshold: if your event draws under 100 signups, manual spot-checking is faster than setting up batch verification. For recurring events with hundreds of registrants, Emailable saves hours and protects your sender reputation across campaigns.
When email verification matters for support workflows
A 4-person support team receives 30-50 inbound tickets daily, many from first-time users. They use Emailable's Verify Email tool in their triage workflow to flag tickets from disposable or invalid addresses before assigning them to agents. This catches spam submissions and prevents wasted time on undeliverable follow-ups. The Get Account Info tool runs at shift start to confirm they have enough credits for the day's volume. The limit: if your ticket volume spikes above 200 per day, the single-verification approach gets slow and you should switch to batching overnight. For small support teams handling moderate inbound, Emailable keeps the queue clean without adding friction to urgent cases.
Frequently asked
What does the Emailable MCP do in Switchy?
It checks whether email addresses are deliverable before you send. The MCP verifies single addresses or batches up to 50,000 at once, returning risk scores and detailed results. You can check account credits, submit batch jobs, and poll for completion—all without leaving your Switchy workspace.
Do I need an Emailable API key to connect this MCP?
Yes. The MCP uses API_KEY authentication, so you'll need an active Emailable account and a valid API key. Paste the key into Switchy's connection flow. The MCP also exposes an OAuth tool if you want to automate token refresh, but the primary auth method is a static API key.
Can the Emailable MCP send emails or manage campaigns?
No. It only verifies deliverability—it doesn't send mail. If you need to act on the verification results, pipe them into another MCP (like SendGrid or Postmark) or export the batch data. Emailable's job is to tell you which addresses will bounce; sending is someone else's job.
Why use this MCP instead of Emailable's dashboard or API directly?
The MCP lets you verify emails inside the same workspace where you're drafting campaigns, cleaning CRM lists, or building lead-gen workflows. You skip context-switching and can chain verification into multi-step automations. If you only verify once a quarter, the dashboard is fine; if it's part of your daily workflow, the MCP saves time.
Does running email verifications count against my Switchy plan limits?
No. Verifications consume credits in your Emailable account, not Switchy tokens or seats. The MCP is just a bridge—Emailable bills you separately for each verification. Check your Emailable credit balance with the Get Account Info tool before submitting large batches.
