Send the announcement from the same API.
Product updates, launch notes, and policy changes go to a list of contacts from your own domain, now or on a schedule. Same templates, same events, same bill as your transactional email.
Announcements usually mean a second tool: another domain to set up, another template system, another contact list that drifts from your app, another bill priced per contact.
Create, send, and watch.
Create the campaign.
A published template or an inline email, sent to an audience picked by tags or contact ids.
Run it now or schedule it.
Pause, resume, or cancel a run while it sends.
Watch each recipient.
See who was sent, failed, or skipped, and why. Unsubscribed, suppressed, or blocked contacts are skipped for you.
Sending a newsletter? See the newsletter API page.
What comes with a campaign.
Unsubscribe handled
One-click unsubscribe on every campaign, plus your brand footer and unsubscribe link.
Paced on new domains
A domain with a warm-up plan paces campaign runs until it is ready.
From anywhere
The dashboard, SDK, REST, the CLI with a dry run, or MCP.
Billed as sends
Each recipient is one email on your plan.
Common questions.
Is this an email marketing platform?
No. A campaign sends one email to a list of contacts. There are no sequences, journeys, or automations.
Can I use my existing templates?
Yes. Send a published template or write the email inline. Either way it goes out from your domain.
Who gets skipped?
Contacts who unsubscribed, are suppressed, or are blocked. Each skipped recipient shows the reason.
How is it billed?
Each recipient is one email on your plan. Plans also include an active-contact allowance, listed on the pricing page.
The rest of the email API.
Send email in one typed call
Transactional email from the SDK, REST, CLI, or your agent through MCP. Retries are safe.
Replies land in your app
Receive on your domain, parsed and threaded to the email it answers, delivered as a signed webhook.
Change the email without a deploy
Versioned templates in Git. Review the diff, publish that version.
Know why an email did or didn't land
SPF and DKIM on your domain, suppression you can see, events for every send.
Send the announcement too
