Question : Which events can Mailpro send me by webhook?

An event webhook (direction A) can subscribe to one or more of the following events (50 per webhook at most). The technical name is what you will receive in the type field of the JSON message.

Contacts, lists and tags

• contact.created, contact.updated, contact.deleted
• list.contact_added, list.contact_removed
• tag.applied, tag.removed, segment.matched

Emails

• email.processed — accepted for sending
• email.delivered — handed over to the recipient's server (single sends via API, SMTP and automation)
• email.opened, email.clicked
• email.bounced — bounce; email.dropped — dropped before sending
• email.unsubscribed, email.spam_report

Campaigns, SMS, imports

• campaign.started, campaign.finished
• sms.queued, sms.sent, sms.delivered, sms.failed
• import.started, import.progress, import.completed, import.failed

Account

• credits.email.low, credits.sms.low — low balance
• api.limit.low, api.limit.reached — API call quota

What you receive

Every event is a JSON POST with a common envelope:

{
"id": "evt_5f2c…",
"type": "email.delivered",
"created": 1758000000,
"apiVersion": "v3",
"account": { "id": 12345, "name": "My company" },
"data": { … details specific to the event … }
}

The content of the data field for each type is described in the Webhooks section of the developer portal.
