Transactional email

Ship email like you ship code.

CommuniQueue is the template workflow layer for transactional email. Draft, test-send, publish, and roll back templates - then send by template id through your own provider. Changing copy never touches a deploy, and your API calls carry an id instead of HTML.

curl -X POST https://api.communiqueue.com/api/v1/notifications/send \
  -H "X-Api-Key: cqk_..." \
  -d '{
    "templateId": "welcome-email",
    "tags": [{ "key": "firstName", "value": "Ada" }]
  }'

The same request before and after every publish - the live version resolves at send time. Pin versionNumber only when you mean it.

Workflow

Templates with a real lifecycle

Draft without fear

Every template has one autosaving draft, edited visually or in HTML with Handlebars variables. The live version keeps sending until you publish.

Test on the real pipeline

Test sends go through the same rendering and delivery path as production - flagged so they never pollute your reports or usage.

Publish and roll back

Publishing goes live instantly. Retained history up to your plan limit stays restorable as a new draft; lock versions you must keep. Recover from a bad copy change in seconds, not a deploy cycle.

Organize everything as workspaces → projects → folders → templates. Folders inherit recipient lists down the tree, so a project-wide address change is one edit.

Economics

Bring your own provider. Keep wholesale rates.

Connect your own SendGrid, Postmark, Mailgun, or Amazon SES account and CommuniQueue sends through it - your reputation, your rates. Or add managed sending at $1 per 1,000 deliveries and skip the setup.

Approximate provider cost at 100,000 emails per month
Sending 100K emails/month	Provider cost
Amazon SES (your key) $0.10 per 1,000 emails, no base fee	~$10
Mailgun Scale 100,000 emails/month included	$90
Postmark Pro their 125K plan, the smallest that covers 100K	$126.50

Visibility

Know what happened to every send

Delivery reports

Per-job, per-template, and per-recipient reporting: delivered, opened, clicked, bounced - with CSV export.

Suppression management

Bounces and complaints suppress automatically; review, add, and remove suppressions across every project in one place.

Soft-bounce thresholds

Set a per-workspace threshold and repeated soft bounces suppress a recipient before they hurt your sender reputation.

Recipients

Named lists, not addresses pasted into every call

Distribution lists

Build a list once - an ops team, a billing group, a small newsletter - save it as a recipient in the app, or send to it by name through the API. Every plan includes lists, and higher tiers include more of them.

Per-recipient personalization

A Marketing send renders once per recipient, so {{recipient.name}} and any custom field on the list member fill in per person - no separate call per address.

Managed from the app or the API

Add one address, paste many, or import a CSV in the app. Manage the same lists programmatically with a Manage lists API key, kept separate from a send-only key.

Workspaces

Every product gets its own workspace

Each workspace has its own templates, team, sending limits, and provider configuration. Basic includes 1 workspace, Pro includes 2, and Business includes 5 in the advertised base plan price.

Plans from $12/month, workspace allowance included

50,000 email deliveries a month on Basic - up to 750,000 on Business
