Integrations

Send transactional email, manage domains, list contacts, and rotate API keys directly from your terminal. Perfect for shell scripts and CI pipelines.

npm install -g @poststack.dev/cli

A complete Zapier app: REST-hook triggers on email.delivered, email.bounced, and contact.created, plus send-email, create-contact, and add-to-segment actions. It is built, but not yet promoted to the public Zapier directory — searching Zapier for PostStack will not find it. Ask us and we will get you connected.

The same three triggers as the Zapier app, plus send-email and create-contact modules for the drag-and-drop scenario editor. Not yet submitted to Make's public app directory, so it is not searchable there. Ask us and we will get you connected.

Pipe inbound mail, bounces, complaints, and deliverability alerts straight into a Slack channel via an incoming webhook. PostStack formats every event as a readable message — no Zap or middleware required.

Post email events to any Discord channel with a channel webhook. Subscribe an ops channel to webhook.disabled and deliverability.degraded and the whole team sees problems the moment they happen.

Get pinged on your phone via a Telegram bot when mail lands or a send bounces. Scope channels team-wide, per-domain, or per-mailbox, with webhook-grade retries and auto-disable.

Install the plugin and paste your API key. Every WordPress notification, from password resets to WooCommerce order confirmations and contact form submissions, routes through PostStack.

wp plugin install poststack

Manage sending domains, API keys, and webhook subscriptions via the official Terraform provider. Pin domains and rotate keys from your existing IaC pipeline.

terraform { required_providers { poststack = { source = "getpoststack/poststack" } } }

Add PostStack to a Vercel project with a single click. Environment variables are wired in automatically and billing rolls into your Vercel invoice.
