Send newsletters and announcements to a segment of contacts with Delivrie broadcasts: personalisation, topics, unsubscribe links, test sends and scheduling, from the dashboard or the API.
A broadcast sends one email to every subscribed contact in a segment: newsletters, product announcements, policy updates. Each recipient gets their own copy with their name filled in and their own unsubscribe link.
{{first_name}} or any contact property.# 1. Create a draft
curl -X POST https://delivrie.io/api/broadcasts \
-H "Authorization: Bearer $DELIVRIE_API_KEY" -H "Content-Type: application/json" \
-d '{
"name": "November newsletter",
"from": "Acme <news@mail.acme.com>",
"subject": "What we shipped in November",
"segment_id": "SEGMENT_ID",
"preview_text": "Three new features and a discount",
"html": "<p>Hi {{first_name|there}},</p><p>...</p><p><a href=\"{{{unsubscribe_url}}}\">Unsubscribe</a></p>"
}'
# 2. Send it now, or schedule it with an ISO 8601 time
curl -X POST https://delivrie.io/api/broadcasts/BROADCAST_ID/send \
-H "Authorization: Bearer $DELIVRIE_API_KEY" -H "Content-Type: application/json" \
-d '{ "scheduled_at": "2026-11-20T08:00:00Z" }'
The send response includes recipients, the number of contacts it will go to. Cancel a scheduled broadcast with POST /broadcasts/:id/cancel (it goes back to draft), and check how many contacts it will reach with GET /broadcasts/:id/recipients.
Every contact in the segment, except contacts who:
| Variable | Inserts |
|---|---|
{{first_name}}, {{last_name}}, {{email}} | The contact's details (escaped). first_name falls back to "there" when empty |
{{plan}}, {{city}}, ... | Any contact property, with the fallback you set for that property |
{{first_name|friend}} | A fallback just for this email |
{{{unsubscribe_url}}} | The recipient's unsubscribe page |
Every broadcast email gets List-Unsubscribe and one-click unsubscribe headers, so Gmail and Apple Mail show their own Unsubscribe button. Include a visible link too, with {{{unsubscribe_url}}}. The page it opens lets people unsubscribe from everything or from one topic, and you can brand it in Settings.
Use broadcasts for the same message to many people. For one-to-one messages triggered by something a user did (receipts, password resets, alerts), use [POST /emails](/docs/send-email) or an automation.
