Data Overview
| Metric | Value |
|---|---|
| Skills in this guide | 53 |
| Workflow stages covered | 6 |
| Top by installs | imap-smtp-email ( installs) |
| Top by downloads | imap-smtp-email ( downloads) |
1. Read & Send — IMAP/SMTP Basics
The foundation of email automation: connecting to any mailbox via IMAP/SMTP to read, send, search, and manage messages. These Skills work across all major providers — Gmail, Outlook, ProtonMail Bridge, QQ Mail, Fastmail, and custom self-hosted servers.
imap-smtp-email is by far the most installed email Skill on the platform, with installs and over 24,000 downloads. Most other IMAP/SMTP skills are derivatives or variants with slightly different defaults.
2. Gmail & Outlook — Platform-Specific Tools
Platform-specific Skills that use OAuth or official APIs rather than raw IMAP/SMTP — more reliable for Gmail and Outlook/Microsoft 365 users, and able to access platform-native features (labels, calendar, Teams integration).
gmail ( installs) and outlook ( installs) are the canonical official-API entries. email-daily-summary stands out with installs — it reads across Gmail, Outlook, and QQ Mail simultaneously.
3. Inbox Triage & Cleanup
Skills for managing inbox overload: bulk-deleting newsletters, categorizing threads, generating summaries, and drafting replies. These are particularly useful when given to an AI agent running periodic inbox maintenance.
gmail-cleaner and its variants focus on bulk operations — identifying and removing low-value emails at scale. expanso-email-triage adds calendar-aware prioritization.
4. Email Marketing & Bulk Sending
Transactional and marketing email via API services — Mailchimp, Mailgun, Resend, and similar. These Skills are typically used in agentic pipelines where an AI needs to send templated emails, drip sequences, or bulk newsletters without a human in the loop.
mailchimp leads on downloads (14,272) despite having only installs — a sign that developers are pulling it for one-off integrations rather than daily agent use.
5. AI Agent Email — Dedicated Inboxes
A newer category: Skills that provision dedicated email addresses for AI agents, rather than accessing a human's inbox. The agent gets its own mailbox, can receive replies, track threads, and act on incoming messages — all programmatically.
AgentMail is the main provider here, with multiple Skills wrapping its API. agentmail-integration is the most complete implementation ( installs).
6. Email Parsing & Extraction
Skills that treat email content as structured data — extracting calendar events from confirmation emails, finding contact addresses for a domain, or defending against prompt injection attacks embedded in email content.
afrexai-email-to-calendar is the standout here: it parses emails to extract deadlines, events, and action items, then syncs them to a calendar. email-security addresses a real concern in agentic workflows — malicious emails can attempt to hijack an agent's behavior.
7. Chinese Email Services
A cluster of Skills targeting Chinese email providers — 163.com, QQ Mail, 139 Mail — which require specific SMTP/IMAP configurations and auth flows that differ from Western providers. email-163-com leads with installs.
Workflow Recommendations
| My situation | Recommended Skills |
|---|---|
| Need a general IMAP/SMTP email client for any provider | imap-smtp-email |
| Using Gmail specifically, want OAuth (not IMAP) | gmail |
| Using Outlook / Microsoft 365 | outlook or outlook-api |
| Want a daily email digest across multiple accounts | email-daily-summary |
| Inbox overrun with newsletters, need bulk cleanup | gmail-cleaner + inbox-cleanup |
| Need to send marketing emails / transactional email | mailgun or mailchimp |
| Building an AI agent that needs its own email address | agentmail-integration |
| Extracting calendar events from confirmation emails | afrexai-email-to-calendar |
| Working with Chinese email providers (163/QQ/139) | imap-smtp-email-chinese or email-163-com |
Final Observations
A few patterns worth noting from the data:
IMAP/SMTP fragmentation is real. There are at least 8 distinct imap-smtp-email variants on the platform (plus, disabled, chinese, welderjustin, etc.). All do roughly the same thing with minor configuration differences. imap-smtp-email is the reference implementation — start there and only switch if you have a specific provider need.
The AI agent inbox category is early but growing fast. AgentMail-based Skills appeared in the last 30 days and already have meaningful download counts. As more workflows require agents to receive and act on replies, expect this category to expand significantly.
Email marketing Skills have high download, low install. Mailchimp downloads (14,272) vs. installs (3) is a dramatic gap — developers try it in a script and don't commit to daily agent use. This suggests most email marketing automation is still run as one-off tasks rather than persistent agent behaviors.
Email security is underused. email-security has 0 installs despite being one of the few Skills that explicitly addresses prompt injection via email. For any production agentic email workflow, it deserves a look.
