Mailgun integration

Mailgun transactional email and validation

Mailgun is the developer-focused transactional email service — competing with SendGrid, Postmark, and Resend on the same fundamentals (HTTP API + SMTP, deliverability tooling, event tracking) with a long-standing reputation in the developer community. Tiny Command exposes three actions, no triggers (Mailgun emits delivery, open, click, bounce events via per-domain webhooks configured in admin Webhooks; point at a Tiny Command webhook trigger URL): Send Email (HTML/text body, attachments, per-recipient variables for batched personalised sends), Validate Email (Mailgun's email-validation service — checks deliverability without sending), Get Events (paginated event log query — useful for "what happened to this email I sent" forensics). The connection uses a Mailgun API key plus the sending domain (the verified domain at your Mailgun account). The EU region uses a different API base URL (api.eu.mailgun.net) — set this at connection time for EU-residency accounts.

Actions

Do anything Mailgun can do, from a workflow.

Every action accepts dynamic inputs from upstream nodes, whether that's an AI output, a form field, or a search result.

Action	What it does	Inputs	Open action
Get Mailgun Events	Paginated event log (delivered, opened, clicked, bounced, failed, complained) with filters by date, message-id, recipient. For "did this email actually deliver?" forensics or bulk-export to warehouse.	2 inputs	View
Mailgun Send Email	Sends transactional or bulk email with HTML/text body, attachments, per-recipient variables for batched personalised sends. The standard hook for "external event → transactional email" patterns.	9 inputs	View
Mailgun Validate Email	SMTP-handshake + DNS + Mailgun-heuristic validation. Returns deliverable/undeliverable/risky/unknown. Useful for in-flow validation before adding to sequences.	1 input	View

Before you build

Three things worth knowing.

Filter at the trigger

Each workflow step uses 1 credit. Put a filter right after the trigger: events that don't match stop there and only use credits for the steps that already ran.

Authorize once, reuse anywhere

Connect Mailgun once and every workflow on your account can use its triggers and actions. You don't have to re-auth per workflow.

No JSON to read

Every Mailgun field shows up in the visual picker for downstream nodes. The raw payload is there for power users, optional for everyone else.

FAQ

Questions about the Mailgun integration.

If we missed yours, ping support. We usually reply within an hour.

How do I connect Mailgun to TinyCommand?

Open the TinyCommand workflow builder, drop in a Mailgun node, and click Connect. Authorize Mailgun once and any workflow on your account can use its triggers and actions. Most teams finish the connection in under two minutes.

What Mailgun triggers does TinyCommand support?

TinyCommand focuses on outbound actions for Mailgun today. Use TinyCommand's universal Webhook or Schedule trigger to start Mailgun workflows, then run any Mailgun action you need.

What Mailgun actions can I run from a workflow?

3 Mailgun actions are available out of the box, covering email operations like "Get Mailgun Events". Every action accepts dynamic inputs from upstream nodes, whether that's a search result, an AI output, or a form field.

Is the Mailgun integration real-time?

Mailgun actions execute synchronously inside your workflow. TinyCommand waits for Mailgun's API to confirm before continuing to the next step, so downstream nodes can rely on the result.

Do I need to write code to use Mailgun with TinyCommand?

No. Every Mailgun trigger and action is fully configurable from the visual workflow builder. For edge cases that aren't covered, drop in a custom HTTP node and call any Mailgun API endpoint directly.

How much does the Mailgun integration cost?

The Free plan includes 1,000 credits a month and every integration, with no credit card. Each workflow step uses 1 credit, and paid plans include more credits and team seats. The Mailgun integration itself has no per-app surcharge.
