Brevo Automation via Rube MCP

Automate Brevo (formerly Sendinblue) email marketing operations through Composio's Brevo toolkit via Rube MCP.

Prerequisites

• Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
• Active Brevo connection via RUBE_MANAGE_CONNECTIONS with toolkit brevo
• Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

1. Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
2. Call RUBE_MANAGE_CONNECTIONS with toolkit brevo
3. If connection is not ACTIVE, follow the returned auth link to complete Brevo authentication
4. Confirm connection status shows ACTIVE before running any workflows

Core Workflows

1. Manage Email Campaigns

When to use: User wants to list, review, or update email campaigns

Tool sequence:

1. BREVO_LIST_EMAIL_CAMPAIGNS - List all campaigns with filters [Required]
2. BREVO_UPDATE_EMAIL_CAMPAIGN - Update campaign content or settings [Optional]

Key parameters for listing:

• type: Campaign type ('classic' or 'trigger')
• status: Campaign status ('suspended', 'archive', 'sent', 'queued', 'draft', 'inProcess', 'inReview')
• startDate/endDate: Date range filter (YYYY-MM-DDTHH:mm:ss.SSSZ format)
• statistics: Stats type to include ('globalStats', 'linksStats', 'statsByDomain')
• limit: Results per page (max 100, default 50)
• offset: Pagination offset
• sort: Sort order ('asc' or 'desc')
• excludeHtmlContent: Set true to reduce response size

Key parameters for update:

• campaign_id: Numeric campaign ID (required)
• name: Campaign name
• subject: Email subject line
• htmlContent: HTML email body (mutually exclusive with htmlUrl)
• htmlUrl: URL to HTML content
• sender: Sender object with name, email, or id
• recipients: Object with listIds and exclusionListIds
• scheduledAt: Scheduled send time (YYYY-MM-DDTHH:mm:ss.SSSZ)

Pitfalls:

• startDate and endDate are mutually required; provide both or neither
• Date filters only work when status is not passed or set to 'sent'
• htmlContent and htmlUrl are mutually exclusive
• Campaign sender email must be a verified sender in Brevo
• A/B testing fields (subjectA, subjectB, splitRule, winnerCriteria) require abTesting: true
• scheduledAt uses full ISO 8601 format with timezone

2. Create and Manage Email Templates

When to use: User wants to create, edit, list, or delete email templates

Tool sequence:

1. BREVO_GET_ALL_EMAIL_TEMPLATES - List all templates [Required]
2. BREVO_CREATE_OR_UPDATE_EMAIL_TEMPLATE - Create a new template or update existing [Required]
3. BREVO_DELETE_EMAIL_TEMPLATE - Delete an inactive template [Optional]

Key parameters for listing:

• templateStatus: Filter active (true) or inactive (false) templates
• limit: Results per page (max 1000, default 50)
• offset: Pagination offset
• sort: Sort order ('asc' or 'desc')

Key parameters for create/update:

• templateId: Include to update; omit to create new
• templateName: Template display name (required for creation)
• subject: Email subject line (required for creation)
• htmlContent: HTML template body (min 10 characters; use this or htmlUrl)
• sender: Sender object with name and email, or id (required for creation)
• replyTo: Reply-to email address
• isActive: Activate or deactivate the template
• tag: Category tag for the template

Pitfalls:

• When templateId is provided, the tool updates; when omitted, it creates
• For creation, templateName, subject, and sender are required
• htmlContent must be at least 10 characters
• Template personalization uses {{contact.ATTRIBUTE}} syntax
• Only inactive templates can be deleted
• htmlContent and htmlUrl are mutually exclusive

3. Manage Senders

When to use: User wants to view authorized sender identities

Tool sequence:

1. BREVO_GET_ALL_SENDERS - List all verified senders [Required]

Key parameters: (none required)

Pitfalls:

• Senders must be verified before they can be used in campaigns or templates
• Sender verification is done through the Brevo web interface, not via API
• Sender IDs can be used in sender.id fields for campaigns and templates

4. Configure A/B Testing Campaigns

When to use: User wants to set up or modify A/B test settings on a campaign

Tool sequence:

1. BREVO_LIST_EMAIL_CAMPAIGNS - Find the target campaign [Prerequisite]
2. BREVO_UPDATE_EMAIL_CAMPAIGN - Configure A/B test settings [Required]

Key parameters:

• campaign_id: Campaign to configure
• abTesting: Set to true to enable A/B testing
• subjectA: Subject line for variant A
• subjectB: Subject line for variant B
• splitRule: Percentage split for the test (1-99)
• winnerCriteria: 'open' or 'click' for determining the winner
• winnerDelay: Hours to wait before selecting winner (1-168)

Pitfalls:

• A/B testing must be enabled (abTesting: true) before setting variant fields
• splitRule is the percentage of contacts that receive variant A
• winnerDelay defines how long to test before sending the winner to remaining contacts
• Only works with 'classic' campaign type

Common Patterns

Campaign Lifecycle

1. Create campaign (status: draft)
2. Set recipients (listIds)
3. Configure content (htmlContent or htmlUrl)
4. Optionally schedule (scheduledAt)
5. Send or schedule via Brevo UI (API update can set scheduledAt)

Pagination

• Use limit (page size) and offset (starting index)
• Default limit is 50; max varies by endpoint (100 for campaigns, 1000 for templates)
• Increment offset by limit each page
• Check count in response to determine total available

Template Personalization

- First name: {{contact.FIRSTNAME}}
- Last name: {{contact.LASTNAME}}
- Custom attribute: {{contact.CUSTOM_ATTRIBUTE}}
- Mirror link: {{mirror}}
- Unsubscribe link: {{unsubscribe}}

Known Pitfalls

Date Formats:

• All dates use ISO 8601 with milliseconds: YYYY-MM-DDTHH:mm:ss.SSSZ
• Pass timezone in the date-time format for accurate results
• startDate and endDate must be used together

Sender Verification:

• All sender emails must be verified in Brevo before use
• Unverified senders cause campaign creation/update failures
• Use GET_ALL_SENDERS to check available verified senders

Rate Limits:

• Brevo API has rate limits per account plan
• Implement backoff on 429 responses
• Template operations have lower limits than read operations

Response Parsing:

• Response data may be nested under data or data.data
• Parse defensively with fallback patterns
• Campaign and template IDs are numeric integers
