Email settings

Open pixels, click redirects and unsubscribe links use https://marketing.puro-systems.com (the APP_URL setting in .env).

For best deliverability, use a sub-domain of each sending domain (e.g. track.getpuro.com) with a CNAME pointing to this server. A tracking domain that matches the sender domain looks more trustworthy to spam filters.

Emails or whole domains that must never be contacted (competitors, existing customers, people who asked to stop). Applies to every campaign.

POST a JSON payload to a URL on every event, to connect n8n, Zapier, Make or your CRM. Payload: { event, data, contact }. Bot opens/clicks are not sent.
