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. No deploys. No HTML in your API calls.

curl -X POST https://api.communiqueue.com/api/v1/notifications/send \
  -H "X-Api-Key: cq_live_..." \
  -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 use our built-in sending and skip the setup. Either way, you pay us for the workflow, not the volume.

Approximate provider cost at 100,000 emails per month

Amazon SES (your key) $0.10 per 1,000 emails, no base fee	~$10
Mailgun Scale retail plan at 100K emails/month	$90
Postmark Pro base + overage at 100K emails/month	~$133.50

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.

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 $29/month, workspace allowance included

10,000 email deliveries included on Basic - up to 150,000 on Business
