Sendgrid Automation V2

SendGrid Automation via Rube MCP

Overview

This public intake copy packages plugins/antigravity-awesome-skills/skills/sendgrid-automation from https://github.com/sickn33/antigravity-awesome-skills into the native Omni Skills editorial shape without hiding its origin.

Use it when the operator needs the upstream workflow, support files, and repository context to stay intact while the public validator and private enhancer continue their normal downstream flow.

This intake keeps the copied upstream files intact and uses the external_source block in metadata.json plus ORIGIN.md as the provenance anchor for review.

SendGrid Automation via Rube MCP Automate SendGrid email delivery workflows including marketing campaigns (Single Sends), contact and list management, sender identity setup, and email analytics through Composio's SendGrid toolkit.

Imported source sections that did not map cleanly to the public headings are still preserved below or in the support files. Notable imported sections: Prerequisites, Common Patterns, Known Pitfalls, Limitations.

When to Use This Skill

Use this section as the trigger filter. It should make the activation boundary explicit before the operator loads files, runs commands, or opens a pull request.

• This skill is applicable to execute the workflow or actions described in the overview.
• Use when the request clearly matches the imported source intent: Automate SendGrid email delivery workflows including marketing campaigns (Single Sends), contact and list management, sender identity setup, and email analytics through Composio's SendGrid toolkit.
• Use when the operator should preserve upstream workflow detail instead of rewriting the process from scratch.
• Use when provenance needs to stay visible in the answer, PR, or review packet.
• Use when copied upstream references, examples, or scripts materially improve the answer.
• Use when the workflow should remain reviewable in the public intake repo before the private enhancer takes over.

Operating Table

Workflow

This workflow is intentionally editorial and operational at the same time. It keeps the imported source useful to the operator while still satisfying the public intake standards that feed the downstream enhancer flow.

Imported: Core Workflows

1. Create and Send Marketing Campaigns (Single Sends)

When to use: User wants to create and send a marketing email campaign to a contact list or segment.

Tool sequence:

1. SENDGRID_RETRIEVE_ALL_LISTS - List available marketing lists to target [Prerequisite]
2. SENDGRID_CREATE_A_LIST - Create a new list if needed [Optional]
3. SENDGRID_ADD_OR_UPDATE_A_CONTACT - Add contacts to the list [Optional]
4. SENDGRID_GET_ALL_SENDER_IDENTITIES - Get verified sender ID [Prerequisite]
5. SENDGRID_CREATE_SINGLE_SEND - Create the campaign with content, sender, and recipients [Required]

Key parameters for SENDGRID_CREATE_SINGLE_SEND:

• name: Campaign name (required)
• email__config__subject: Email subject line
• email__config__html__content: HTML body content
• email__config__plain__content: Plain text version
• email__config__sender__id: Verified sender identity ID
• email__config__design__id: Use instead of html_content for pre-built designs
• send__to__list__ids: Array of list UUIDs to send to
• send__to__segment__ids: Array of segment UUIDs
• send__to__all: true to send to all contacts
• email__config__suppression__group__id or email__config__custom__unsubscribe__url: One required for compliance

Pitfalls:

• Setting send_at on CREATE does NOT schedule the send; it only prepopulates the UI date; use the Schedule endpoint separately
• send_at: "now" is only valid with the Schedule endpoint, not CREATE
• Must provide either suppression_group_id or custom_unsubscribe_url for unsubscribe compliance
• Sender must be verified before use; check with SENDGRID_GET_ALL_SENDER_IDENTITIES
• Nested params use double-underscore notation (e.g., email__config__subject)

2. Manage Contacts and Lists

When to use: User wants to create contact lists, add/update contacts, search for contacts, or remove contacts from lists.

Tool sequence:

1. SENDGRID_RETRIEVE_ALL_LISTS - List all marketing lists [Required]
2. SENDGRID_CREATE_A_LIST - Create a new contact list [Optional]
3. SENDGRID_GET_A_LIST_BY_ID - Get list details and sample contacts [Optional]
4. SENDGRID_ADD_OR_UPDATE_A_CONTACT - Upsert contacts with list association [Required]
5. SENDGRID_GET_CONTACTS_BY_EMAILS - Look up contacts by email [Optional]
6. SENDGRID_GET_CONTACTS_BY_IDENTIFIERS - Look up contacts by email, phone, or external ID [Optional]
7. SENDGRID_GET_LIST_CONTACT_COUNT - Verify contact count after operations [Optional]
8. SENDGRID_REMOVE_CONTACTS_FROM_A_LIST - Remove contacts from a list without deleting [Optional]
9. SENDGRID_REMOVE_LIST_AND_OPTIONAL_CONTACTS - Delete an entire list [Optional]
10. SENDGRID_IMPORT_CONTACTS - Bulk import from CSV [Optional]

Key parameters for SENDGRID_ADD_OR_UPDATE_A_CONTACT:

• contacts: Array of contact objects (max 30,000 or 6MB), each with at least one identifier: email, phone_number_id, external_id, or anonymous_id (required)
• list_ids: Array of list UUID strings to associate contacts with

Pitfalls:

• SENDGRID_ADD_OR_UPDATE_A_CONTACT is asynchronous; returns 202 with job_id; contacts may take 10-30 seconds to appear
• List IDs are UUIDs (e.g., "ca7a3796-e8a8-4029-9ccb-df8937940562"), not integers
• List names must be unique; duplicate names cause 400 errors
• SENDGRID_ADD_A_SINGLE_RECIPIENT_TO_A_LIST uses the legacy API; prefer SENDGRID_ADD_OR_UPDATE_A_CONTACT with list_ids
• SENDGRID_REMOVE_LIST_AND_OPTIONAL_CONTACTS is irreversible; require explicit user confirmation
• Email addresses are automatically lowercased by SendGrid

3. Manage Sender Identities

When to use: User wants to set up or view sender identities (From addresses) for sending emails.

Tool sequence:

1. SENDGRID_GET_ALL_SENDER_IDENTITIES - List all existing sender identities [Required]
2. SENDGRID_CREATE_A_SENDER_IDENTITY - Create a new sender identity [Optional]
3. SENDGRID_VIEW_A_SENDER_IDENTITY - View details for a specific sender [Optional]
4. SENDGRID_UPDATE_A_SENDER_IDENTITY - Update sender details [Optional]
5. SENDGRID_CREATE_VERIFIED_SENDER_REQUEST - Create and verify a new sender [Optional]
6. SENDGRID_AUTHENTICATE_A_DOMAIN - Set up domain authentication for auto-verification [Optional]

Key parameters for SENDGRID_CREATE_A_SENDER_IDENTITY:

• from__email: From email address (required)
• from__name: Display name (required)
• reply__to__email: Reply-to address (required)
• nickname: Internal identifier (required)
• address, city, country: Physical address for CAN-SPAM compliance (required)

Pitfalls:

• New senders must be verified before use; if domain is not authenticated, a verification email is sent
• Up to 100 unique sender identities per account
• Avoid using domains with strict DMARC policies (gmail.com, yahoo.com) as from addresses
• SENDGRID_CREATE_VERIFIED_SENDER_REQUEST sends a verification email; sender is unusable until verified

4. View Email Statistics and Activity

When to use: User wants to review email delivery stats, bounce rates, open/click metrics, or message activity.

Tool sequence:

1. SENDGRID_RETRIEVE_GLOBAL_EMAIL_STATISTICS - Get account-wide delivery metrics [Required]
2. SENDGRID_GET_ALL_CATEGORIES - Discover available categories for filtering [Optional]

Key parameters for SENDGRID_FILTER_ALL_MESSAGES:

• query: SQL-like query string, e.g., status="delivered", to_email="user@example.com", date ranges with BETWEEN TIMESTAMP
• limit: 1-1000 (default 10)

Pitfalls:

• SENDGRID_FILTER_ALL_MESSAGES requires the "30 Days Additional Email Activity History" paid add-on; returns 403 without it
• Global statistics are nested under details[].stats[0].metrics, not a flat structure
• Category statistics are only available for the previous 13 months
• Maximum 10 categories per request in SENDGRID_RETRIEVE_EMAIL_STATISTICS_FOR_CATEGORIES
• CSV export is limited to one request per 12 hours; link expires after 3 days

5. Manage Suppressions

When to use: User wants to check or manage unsubscribe groups for email compliance.

Tool sequence:

1. SENDGRID_GET_SUPPRESSION_GROUPS - List all suppression groups [Required]
2. SENDGRID_RETRIEVE_ALL_SUPPRESSION_GROUPS_FOR_AN_EMAIL_ADDRESS - Check suppression status for a specific email [Optional]

Pitfalls:

• Suppressed addresses remain undeliverable even if present on marketing lists
• Campaign send counts may be lower than list counts due to suppressions

Imported: Prerequisites

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

Examples

Example 1: Ask for the upstream workflow directly

Use @sendgrid-automation-v2 to handle <task>. Start from the copied upstream workflow, load only the files that change the outcome, and keep provenance visible in the answer.

Explanation: This is the safest starting point when the operator needs the imported workflow, but not the entire repository.

Example 2: Ask for a provenance-grounded review

Review @sendgrid-automation-v2 against metadata.json and ORIGIN.md, then explain which copied upstream files you would load first and why.

Explanation: Use this before review or troubleshooting when you need a precise, auditable explanation of origin and file selection.

Example 3: Narrow the copied support files before execution

Use @sendgrid-automation-v2 for <task>. Load only the copied references, examples, or scripts that change the outcome, and name the files explicitly before proceeding.

Explanation: This keeps the skill aligned with progressive disclosure instead of loading the whole copied package by default.

Example 4: Build a reviewer packet

Review @sendgrid-automation-v2 using the copied upstream files plus provenance, then summarize any gaps before merge.

Explanation: This is useful when the PR is waiting for human review and you want a repeatable audit packet.

Best Practices

Treat the generated public skill as a reviewable packaging layer around the upstream repository. The goal is to keep provenance explicit and load only the copied source material that materially improves execution.

• Keep the imported skill grounded in the upstream repository; do not invent steps that the source material cannot support.
• Prefer the smallest useful set of support files so the workflow stays auditable and fast to review.
• Keep provenance, source commit, and imported file paths visible in notes and PR descriptions.
• Point directly at the copied upstream files that justify the workflow instead of relying on generic review boilerplate.
• Treat generated examples as scaffolding; adapt them to the concrete task before execution.
• Route to a stronger native skill when architecture, debugging, design, or security concerns become dominant.

Troubleshooting

Problem: The operator skipped the imported context and answered too generically

Symptoms: The result ignores the upstream workflow in plugins/antigravity-awesome-skills/skills/sendgrid-automation, fails to mention provenance, or does not use any copied source files at all. Solution: Re-open metadata.json, ORIGIN.md, and the most relevant copied upstream files. Check the external_source block first, then restate the provenance before continuing.

Problem: The imported workflow feels incomplete during review

Symptoms: Reviewers can see the generated SKILL.md, but they cannot quickly tell which references, examples, or scripts matter for the current task. Solution: Point at the exact copied references, examples, scripts, or assets that justify the path you took. If the gap is still real, record it in the PR instead of hiding it.

Problem: The task drifted into a different specialization

Symptoms: The imported skill starts in the right place, but the work turns into debugging, architecture, design, security, or release orchestration that a native skill handles better. Solution: Use the related skills section to hand off deliberately. Keep the imported provenance visible so the next skill inherits the right context instead of starting blind.

Imported Reference Notes

Imported: Quick Reference

Imported: Common Patterns

ID Resolution

Always resolve names to IDs before operations:

• List name -> list_id: SENDGRID_RETRIEVE_ALL_LISTS and match by name
• Sender name -> sender_id: SENDGRID_GET_ALL_SENDER_IDENTITIES and match
• Contact email -> contact_id: SENDGRID_GET_CONTACTS_BY_EMAILS with email array
• Template name -> template_id: Use the SendGrid UI or template endpoints

Pagination

• SENDGRID_RETRIEVE_ALL_LISTS: Token-based with page_token and page_size (max 1000)
• SENDGRID_RETRIEVE_GLOBAL_EMAIL_STATISTICS: Offset-based with limit (max 500) and offset
• Always paginate list retrieval to avoid missing existing lists

Async Operations

Contact operations (ADD_OR_UPDATE_A_CONTACT, IMPORT_CONTACTS) are asynchronous:

• Returns 202 with a job_id
• Wait 10-30 seconds before verifying with GET_CONTACTS_BY_EMAILS
• Use GET_LIST_CONTACT_COUNT to confirm list growth

Imported: Known Pitfalls

ID Formats

• Marketing list IDs are UUIDs (e.g., "ca7a3796-e8a8-4029-9ccb-df8937940562")
• Legacy list IDs are integers; do not mix with Marketing API endpoints
• Sender identity IDs are integers
• Template IDs: Dynamic templates start with "d-", legacy templates are UUIDs
• Contact IDs are UUIDs

Rate Limits

• SendGrid may return HTTP 429; respect Retry-After headers
• CSV export limited to one request per 12 hours
• Bulk contact upsert max: 30,000 contacts or 6MB per request

Parameter Quirks

• Nested params use double-underscore: email__config__subject, from__email
• send_at on CREATE_SINGLE_SEND only sets a UI default, does NOT schedule
• SENDGRID_ADD_A_SINGLE_RECIPIENT_TO_A_LIST uses legacy API; recipient_id is Base64-encoded lowercase email
• SENDGRID_RETRIEVE_ALL_LISTS and SENDGRID_GET_ALL_LISTS both exist; prefer RETRIEVE_ALL_LISTS for Marketing API
• Contact adds are async (202); always verify after a delay

Legacy vs Marketing API

• Some tools use the legacy Contact Database API (/v3/contactdb/) which may return 403 on newer accounts
• Prefer Marketing API tools: SENDGRID_ADD_OR_UPDATE_A_CONTACT, SENDGRID_RETRIEVE_ALL_LISTS, SENDGRID_CREATE_SINGLE_SEND

Imported: Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
